As changes are made immediately and automatically, it saves the time and effort in coordinating them in all other associated views which for most projects is an inevitable part of the design process. Autodesk Revit Architecture also provides a variety of in-built parametric element libraries that can be selected and used to create a building model. It also provides you with the flexibility of modifying properties of these elements or create your own parametric elements based on the project requirement.
Before using Autodesk Revit Architecture, it is important to understand the basic terms used for creating a building model. Various terms in Autodesk Revit Architecture such as project, level, category, family, type, and instance are described next. A project in Autodesk Revit Architecture is similar to an actual architectural or interior project. In an actual project, the entire documentation such as drawings, 3D views, specifications, schedules, cost estimates, and so on are inherently linked and read together.
Similarly, in Autodesk Revit Architecture, a project not only includes the digital 3D building model but also its parametrically associated documentation. Thus, all the components such as the building model, its standard views, architectural drawings, and schedules combine together to form a complete project. A project file contains all the project information such as building elements used in a project, drawing sheets, schedules, cost estimates, 3D views, renderings, walkthroughs, and so on.
A project file also stores various settings such as environment, lighting, and so on. As data is stored in the same file, it becomes easier for Autodesk Revit Architecture to coordinate the entire database. In Autodesk Revit Architecture, a building model is divided into different levels. These levels may be understood as infinite horizontal planes that act as hosts for different elements such as roof, floor, ceiling, and so on. The defined levels in a building model can in most cases relate to different floor levels, or stories of the building project.
Each element that you create belongs to a particular level. Apart from building elements, an Autodesk Revit Architecture project also contains other associated elements such as annotations, imported files, links, and so on. These elements have been divided into following categories:. Model Category : Consists of various building elements used in creating a building. Annotation Category : Consists of annotations such as dimensions, text notes, tags, symbols,.
Datum Category : Consists of datums such as levels, grids, reference planes, and so on. View Category : Consists of interactive project views such as floor plans, ceiling plans, elevations, sections, 3D views, renderings, and walkthroughs. In addition to these four categories, other categories such as Imported , Workset , Filter , and Revit Categories can also exist if the project has imported files, enabled worksets, or linked Autodesk Revit Architecture projects, respectively.
Another powerful concept in Autodesk Revit Architecture is family. A family is described as a set of elements of the same category that can be grouped together based on certain common parameters or characteristics. Elements of the same family may have different properties, but they all have common characteristics. For example, Double Hung is a single window family, but it contains different sizes of double hung windows.
Family files have a. You can load additional building component families from the libraries provided in Autodesk Revit Architecture package. Families are further divided into certain types. Type or family type, as it is called, is a specific size or style of a family. For example, Double Hung : 36 x 48 is a window type. All uses of the same family type in a project have same properties. Family and family types can also be used to create new families using the Family Editor. Instances are the actual usage of model elements in a building model or annotations in a drawing sheet.
A family type created in a new location is identified as an instance of the family type. All instances of the same family type have same properties. Therefore, when you modify the properties of a family type, the properties of all its instances also get modified. The family categorization of Revit elements is given below:. The hierarchy of building elements in Autodesk Revit Architecture plays an important role in providing the flexibility and ease of managing a change in the building model.
Figure shows the hierarchy of categories and families in a typical Autodesk Revit Architecture project. The following is another example of the terms described in this section. Another classification of categories of elements followed in Autodesk Revit Architecture is based on their usage.
Autodesk Revit Architecture uses five classes of elements: host, component, annotation, view, and datum. Hosts are the element categories that form the basic structure of a building model and include model elements such as walls, floor, roof, and ceiling. Components are the elements that are added to host elements or act as stand-alone elements such as doors, windows, and furniture.
Annotations are the 2D, view-specific elements that add content to the project documentation such as dimensions, tags, text notes, and so on. Views represent various orientations of a building model such as plans, elevations, sections, 3D views, and so on.
Datum refers to the reference elements that assist you in creating a building model, which include grids, levels, reference planes, and so on. There is no specific methodology available for creating a building model in Autodesk Revit Architecture. It provides you with the flexibility of generating building geometry based on the project requirement, design complexity, and other factors. However, the following steps describe a general procedure that may be followed for creating an architectural building model using the in-built parametric elements provided in Autodesk Revit Architecture.
The first step is to create the exterior walls of a building at the predefined lowest level level 1. Next, create interior walls at that level and add components to the building model. Then, define the upper levels based on the story height of the building. You can also link the control height of the walls to the levels and extend the exterior walls to their full height.
Next, create floors and roof using the defined levels. Add the site topography to the building model and then add site components to complete the building project. You can then create drawing sheets with the desired views for its presentation. Autodesk Revit Architecture also provides tools to create rendered 3D views and walkthroughs.
Figure shows an example of a building section with various building elements and annotations. Autodesk Revit Architecture enables you to control the display and graphic representation of a single element or the element category of various elements in project views by using the visibility and graphics overrides tools.
You can select a model category and modify its linetype and detail level. This can also be done for various annotation category elements and imported files. These settings can be done for each project view based on its desired representation.
You can also hide an element or an element category in a view using the Hide in View and Isolate tools. The scale is another important concept in an Autodesk Revit Architecture project.
As you set a scale, Autodesk Revit Architecture automatically sets the detail level appropriate for it. You can also set the detail level manually for each project view. Each detail level has an associated linetype and the detail lines associated with it. The details of annotations such as dimensions, tags, and so on are also defined by the selected scale. A single integrated building information is used to create and represent a building project.
You can extract project information from a building model and create area schemes, schedule, and cost estimates, and then add them to the project presentation. Autodesk Revit Architecture also enables you to export the extracted database to the industry standard Open Database Connectivity ODBC compliant relational database tables.
The use of the building information model to extract database information eliminates the error-prone method of measuring building spaces individually. After creating the building model, you can easily arrange the project views by plotting them on drawing sheets. Drawing sheets can also be organized in a project file based on the established CAD standards followed by the firm. In this manner, the project documentation can easily be transformed from the conceptual design stage to the design development stage and finally to the construction document stage.
The project view on a drawing sheet is only a graphical representation of the building information model and therefore, any modification in it is immediately made in all the associated project views, keeping the drawings set always updated. Autodesk Revit Architecture also helps you conceptualize a building project in terms of its volume, shape, and proportions before working with the actual building elements. This is possible by using the Massing tool, which enables you to create quick 3D models of buildings and conduct volumetric and proportion study on overall masses.
It also enables you to visualize and create an unusual building geometry. The same massing model can then be converted into a building model with individual parametric building elements. It provides continuity in the generation of building model right from sketch design to its development. Autodesk Revit Architecture provides a large number of in-built family types of various model elements and annotations.
Each parametric element has the associated properties that can be modified based on the project requirement. Autodesk Revit Architecture also enables you to create the elements that are designed specifically for a particular location. The in-built family editor enables you to create new elements using family templates. This provides you with the flexibility of using in-built elements for creating your own elements.
For example, using the furniture template, you can create a reception desk that is suitable for a particular location in the design. An extensive in-built library of structural elements has been provided in Autodesk Revit Architecture. You can add structural columns, beams, walls, braces, and so on to the project. Thus, structural consultants can also incorporate their elements in the basic architectural building model and check for inconsistency, if any.
In Autodesk Revit Architecture, you can work on large projects by linking different building projects together. For a large project that consists of a number of buildings, you can create individual buildings as separate projects and then link all of them into a single base file. The database recognizes the linked projects and includes them in the project representation of the base file. For example, while working on a large campus of an educational institution, you can create separate project files for academic building, administration area, gymnasium, cafeteria, computer centre, and so on, and then link them into the base site plan file.
In this manner, large projects can be subdivided and worked upon simultaneously. Worksets in Autodesk Revit Architecture enable the division of the building model into small editable set of elements. The worksets can be assigned to different teams working on the same project and then their work can easily be coordinated in the central file location.
The effort required to coordinate, collaborate, and communicate the changes between various worksets is taken care of by computer. Various consultants working on a project can be assigned a workset with a set of editable elements.
They can then incorporate their services and modify the associated elements. For example, a high rise commercial building project can be divided into different worksets with independent teams working on exterior skin, interior walls, building core, toilet details, finishes, and so on.
The structural consultants can be assigned the exterior skin and the core workset in which they can incorporate structural elements. Similarly, the rest of the teams can work independently on different worksets. When you turn on your computer, the operating system is automatically loaded. You can start Autodesk Revit Architecture by double-clicking on the Revit Architecture icon on the desktop.
Figure Starting Autodesk Revit Architecture using the taskbar. The path for starting Autodesk Revit Architecture depends on the operating system being used. The interface screen has three sections: Projects , Families , and Resources.
The options in the Projects section are used to open an existing project, a new project, and an existing template. The options in the Families section are used to open a new or an existing family.

Autodesk Revit Architecture has ribbon interface. The ribbon which contains task-based tabs and panels, streamlines the architectural workflow and optimizes the project delivery time. In Autodesk Revit Architecture, when you select an element in the drawing area, the ribbon displays a contextual tab that comprises of tools corresponding to the selected element.
The interface of Autodesk Revit Architecture is similar to the interfaces of many other Microsoft Windows based programs. Figure The Autodesk Revit Architecture user interface screen. To perform an operation, you can invoke the required tools by using any one of the following two options:.
Shortcut Keys : Some tools can also be invoked by using the keys on the keyboard. Project 1- Floor Plan: Level 1 is the default project and view. The ribbon, as shown in Figure , is an interface that is used to invoke tools. When you open a file, the ribbon is displayed at the top in the screen. It comprises of task-based tabs and panels, refer to Figure , which provide all the tools necessary for creating a project.
The tabs and panels in the ribbon can be customized according to the need of the user. This can be done by moving the panels and changing the view states of the ribbon changing the ribbon view state is discussed later in this chapter. The ribbon has three types of buttons are available in: general button, drop-down button, and split button. These buttons can be invoked from the panels. In the ribbon, you can move a panel and place it anywhere on the screen. To do so, press and hold the left mouse button on the panel label in the ribbon, drag it to some desired place on the screen.
Next, use the tools of the moved panel and place the panel back to the ribbon. To do so, place the cursor on the moved panel and choose the Return Panels to Ribbon button from the upper right corner of this panel, as shown in Figure ; the panel will return to the ribbon. The ribbon can be displayed in three view states by selecting any of the following four options: Minimize to Tabs , Minimize to Panel Titles , Minimize to Panel Buttons , and Cycle through All.
To use these options, move the cursor and place it over the second arrow on the right of the Modify tab, refer to Figure in the ribbon; the arrow will be highlighted.
Now, click on the down arrow; a flyout will be displayed, as shown in Figure In this flyout, you can choose the Minimize to Tabs option to display only the tabs in the ribbon. If you choose the Minimize to Panel Titles option, the ribbon will display the titles of the panels along with the tabs.

If the view state of the ribbon is changed, place the cursor over the first arrow at the right of the Modify tab, the Show Full Ribbon tooltip will be displayed. Click on the arrow; full ribbon will be displayed.
These tabs are displayed when you choose certain tools or select elements. These tabs contain a set of tools or buttons that relate only to a particular tool or element.
For example, when you invoke the Window tool, the Modify Place Window contextual tab is displayed. The Select panel contains the Modify tool. The Properties panel contains the Properties button and the Type Properties tool. The Mode panel has some necessary tools that are used to load model families or to create the model of a window in a drawing.
The other panels, apart from those discussed above, contain the tools that are contextual and are used to edit elements when they are placed in a drawing or selected from a drawing for modification.
The application frame helps you manage projects in Autodesk Revit Architecture. These are discussed next. The Application button is displayed at the top-left corner of the Revit interface.
This button is used to display as well as close the Application Menu. The Application Menu contains the tools that provide access to many common file actions such as Open , Close , and Save.
Click the down arrow on the Application button to display the Application Menu , as shown in Figure The Quick Access Toolbar , as shown in Figure , contains the options to undo and redo changes, open and save a file, create a new file, and so on. You can customize the display of the Quick Access Toolbar by adding more tools and removing the unwanted tools. To add a tool or a button from the panel of the ribbon to the Quick Access Toolbar , place the cursor over the button; the button will be highlighted.
Next, right-click; a flyout will be displayed. The Quick Access Toolbar can be customized to re-order the tools displayed in it. To do so, choose the down arrow next to the Switch Windows drop-down, refer to Figure ; a flyout will be displayed. Use various options in this dialog box and choose the OK button; the Customize Quick Access Toolbar dialog box will close and the tools in the Quick Access Toolbar will be re-ordered.

The model visibility has now changed to mainly show the floor slab and stairs. All the walls, doors, etc. It is expected that you will refer back to the previous steps if you need a review on the process. Create the following Structural Plans: a. Level 2 i. Name: Level 2 — Structural Framing Plan ii. View Template to apply: Structural Framing Plan b. Roof i. Name: Roof — Structural Framing Plan ii. View Template to apply: Structural Framing Plan Loading Content: Now that the structural views are set up and ready to go, you will look at how structural content is loaded into the project.
This section will just show you how to load a few elements. As you work through the rest of this chapter, you will have to load additional content; reference this information if needed. This content should have been installed with the Revit Structure application.
If not, it can be downloaded from Autodesk. Type the Family name into the Seek search box on the Insert tab.
Double-click on the Structural folders to explore them and then go back to the US Imperial folder. First, you will load a steel column.
Double-click the Structural Columns folder to open it. Notice the Structural Columns folder is also broken down further into types of material; see list to right. Double-click the Steel folder to open it. Even though there are only eleven Families listed here, they represent hundreds of column sizes.
Each column has several Types defined for the various standard sizes available in the USA. F YI : A Type is a group of parameters with specific values entered for a parametric family. See Chapter 16 for more on Families and Types. Most Families load all the Types associated with them. For example, a table might have three sizes, each defined as a type. When the table is loaded into a project, all three types are loaded and are available for use by the designer. With steel shapes, however, there are way too many Types to have them all loaded into the project.
If they were, the file would be bogged down with excess data and it would make finding the sizes you need more difficult. Revit uses Type Catalogs to deal with Families that have a large set of Types.
A Type Catalog is simply a list that is provided just below loading the family, from which you can choose one or more Types to be loaded from the family.
Other Types can be added later at any time. Click OK to load it. You will use the same technique to load two beams and two bar joists. Use the techniques just described load the following content: a. Click Overwrite the existing version. Save your law office project. First, you will start with the grid layout; structural engineers do this with several rules-of-thumb in mind and experience. Once the grid is laid out with total spans and maximum depths of structural elements in mind, the columns can be placed.
Finally, in this exercise, you will place the beams which span between the columns. This is handy when the structural designer or technician wants to visualize and validate the structural model without the other building elements obscuring the view. Location of Grids, Columns and Beams in Exterior Walls: Placing a grid is simple and has been covered in one of the introductory chapters see Exercise 2, Lesson You will not align and lock these grids to the exterior wall as was done in that chapter because the grid line does not fall directly on any of the lines within the wall.
The image below shows the typical location of the grid line relative to the exterior wall. See the next page for a few comments regarding the image below. You have not drawn this yet; however the column will be bearing on the foundation wall or a concrete pier, not the concrete slab on grade.
This provides a thermal break which keeps the steel column from getting cold, or warm, depending on the climate, and causing condensation to occur. Adding gypsum board and metal furring costs more, as well as the floor and ceiling needing to be notched around these bumps in the walls.
Notice in Figure Use caution when dimensioning to this wall, ensuring you do not pick this line rather than the main exterior face. This element within the wall is called a Sweep. Unfortunately they cannot be hidden from the floor plan view, so you have to work around them.
Looking at Figure Therefore the columns are also positioned to maintain the sheathing as it passes by the studs on the exterior side of the studs. As you can see, the beam just fits behind the sheathing. If the column were any closer to the exterior, the beams would poke out into the cold, or warm, air space.
Pre-cast sill identified in F YI : In this tutorial you are using a prebuilt wall i. Figure However, it would be a good idea to provide rigid insulation on the exterior side of the studs for a more uniform insulation barrier at the floor edges and structural locations. Open your law office using Revit Structure. Switch to the Architectural Level 1 floor plan view. Use the Grid tool.
See page , if needed, for more information. The Grid tool is identical in functionality across the Revit platform. Layout the grid as shown in Figure T IP : Draw a grid using the Align tool to position it along the exterior face of the exterior wall. Do not lock the alignment. Do not add the dimensions at this time. When locked, they will all move together when just one grid bubble or end point is moved. Use this as an opportunity to double-check the overall dimensions of your building.
Additionally, Figure Grids are usually laid out with numbers across the top and letters along one side. A few goals a structural engineer strives for is simplicity, repetition and consistency.
If the spans are the same and the loads are the same, the structural members can usually be the same, thus making it more straight-forward to design and build. This is not necessarily a bad thing, as steel can come in pretty much any length one needs. Also, on the second floor there is a law library which significantly increases the loads in that area, thus requiring deeper beams and joists.
F YI : In the image below Figure First off, this is an abbreviation which should only be used if it has been defined in an abbreviation list somewhere in the set of documents. When the box is checked, a grid bubble shows up at that end. It is possible to have a grid bubble at both ends of the grid line; it is also possible to have the bubble turned off at each end.
The padlock shows that you properly aligned this end of the grid with the adjacent grids while sketching it, per the previous steps. Thus, when one grid end is repositioned, they will all move together. If one needed to move it apart from the others, you simply click on the Padlock to unlock it. The 3D symbol means, if you reposition the grid, the 3D plane this grid represents will move and possibly affect other views. If you click the 3D symbol, it becomes a 2D symbol and only the current view is adjusted.
This only relates to changing the overall length of the grid in a view s. If the grid is ever moved in the other direction , the grid will always instantly update in all views; it is not possible for the same grid to be in two contradicting locations.
The small circle grip at the end of the grid line is what you click and drag on to reposition the end of the grid, the length. This can be hard to select if you are not zoomed in far enough. This is helpful when two grids are close to each other and would otherwise overlap. This option is often accidentally selected when trying to reposition the grid when zoomed out too far.
If this happens, click Undo, zoom in and try again. This will be covered more later, but for now you will simply explore the results. Switch to the Level 2 Architectural Floor Plan view. Notice the grids appear Figure Later, when you study elevations and sections, you will see grids automatically show up in those views as well.
When modeling in Revit, you often need to model things the way they would be built. So, if the column size changed, you would need to stop and start a new column where the size change occurred. Another consideration is column heights; they can only be so long before they do not fit on a truck; column splits are usually a few feet above the floor level. Switch to the Level 2 — Structural Framing Plan.
Zoom in to the intersection of Grids 2 and C. This is the Structural Column tool rather than Architectural Column. Click, using Snaps, at the intersection of Grids 2 and C. You have now added a structural column to the model! This column will show up in all views of the project. Next you will look at a few properties related to the column you just placed, before placing the remaining columns. This is why you were instructed to switch to Level2, rather than Level 1.
Notice, back in Figure Select the new column in the Level 2 Structural Plan view. Note the information listed in the Properties Palette.
Notice, in Figure Also, Revit is keeping track of the grid lines when the column falls directly on them. Next you will change the Top Level to Roof so the column fully extends from Level 1 up to the Roof level. Be sure to add the minus sign. Change the Top Level to Roof. Click Apply or simply move your cursor back into the drawing window. This new column will now show up on the Level 2 architectural plan as well as the Roof structural plan. You will now add the remaining columns to the Level 2 — Structural Framing Plan view.
Place twenty additional columns. See Figure A temporary circle has been added at each column location to help highlight them. Do not add this circle. Do not change the column height; this will be done later using the Filter tool. Notice not all grid intersections have a column.
With all 21 columns placed, drag a selection window around the entire drawing which will select everything in the view. Immediately to the left of that is the Filter icon. The Filter tool allows you to narrow down your selection to a specific group of elements i.
You will explore this next. Click the Filter icon at the lower right corner of the window; see Figure Click the Check None button; see Figure Check the Structural Columns Filter icon and number category; see Figure Notice a total count break down is listed to the right of each category.
Only categories that have selected elements are listed; as you can see Doors is not listed, but would be if any were selected. Click OK to close the Filter dialog and change what is currently selected.
Now that you have filtered elements down to just the Structural Columns, you can easily change the top and base settings. Per steps , do the following to the selected columns: a. Set the Top Level to Roof. A bay here is an area enclosed by four grids. This tutorial started with the architectural walls on the correct location, so you will not have to move any walls to account for the newly added structural elements. Controlling Visibility: In this case, just before placing your first beam, you decide you want to turn off the curtain wall i.
These were not turned off by the View Template you had previously applied to this view. Set Filter list to Show all. For now you will place them directly below the floor. However, later the vertical position of the beam will be adjusted downward when a bar joist is bearing on it more on all this later.
The first thing you will do is load a tag which will display the beam size for each member. The tag is added automatically as you model the structural framing members. Zoom in on Grid line D, between Grids 1 and 2. Select W24x55 from the Type Selector; see Figure Make sure Tag on Placement is selected on the Ribbon. Any sizes needed, but not listed in the Type Selector, must be loaded per the instructions in the previous exercise. It is best to limit the number of steel shapes and sizes to those actually needed in the project.
This should help reduce errors when selecting sizes and make finding what you want easier and faster. Notice the Options Bar in the image below; the placement plane is where the top of the beam will be placed.
The default is based on the current view. Because there is not an Offset option on the Options Bar, you will adjust the vertical position of the beam after it is placed. The beam will be created and appear as shown below in Figure Notice a tag was placed above the beam which indicates its size.
Press the Esc key twice or click Modify to deactivate the Beam tool. The floors drawn by the architects, or you in Chapter 7, will be refined in the next chapter. This anticipated thickness will be used to reposition the beam vertically.
Currently the top of the beam aligns with the top of the floor. Additionally, some beams support bar joists, which in turn support the floor. The beams which support bar joists need to be lowered to accommodate the thickness of the bar joist at the bearing location. The beams which do not support bar joists, perhaps for frame rigidity, shear and edge of slab conditions, need to be directly below the slab.
The two typical beam conditions can be seen in the sections shown in Figures Also, a snapshot of the completed structural framing plan shows the direction the joists are spanning Figure Note the direction of the bar joists which support the floor. Select the Beam and view its properties via the Properties Palette Figure Change… a.
Click Apply to commit the change. With the beam still selected, see the image and comment on the next page. When the beam is selected you see the elevation of the beam listed at each end. This text is blue, which means you can select it and edit it without needing to open the properties dialog. This is particularly handy for sloped beams.
However, the Properties Palette may be the better way to go once the bar joists have been placed. When changed via properties, Revit does not make any changes to the model until you click Apply.
When you change the on-screen text at one end, it makes the change to that end immediately. Revit may pause as it calculates repositioning all the bar joists along a sloped beam. Then you wait again when the other end is modified.
This is great when the beam does slope! Finally, the triangular grips at each end allow you to manually adjust the one-line beam end location. At each end, the beam stops short of the column or wall to make the drawing more readable.
This conforms to industry standard structural drafting techniques. Next you will place the remaining beams for this elevation on Level 2. Place all the beams shown in Figure All beams shown are at Select the correct beam size via the Type Selector.
Load additional beams sizes as needed per steps previously covered. T IP : Place all beams and then select them using the Filter tool and change the vertical positions all at once. Sometimes things such as notes or dimensions are in the way and the tag is not legible. It is possible to select the tag and move it via the Move tool or by dragging it. The image above has a few such modifications: at both of the stairs and the floor opening in the Northeast corner of the building.
Next, you will add framing for the floor opening. In the next steps you will place a few beams that are supported by other beams. Revit will automatically notify the user of this problem; see image to the right. Place the W24x55 beam approximately as shown in Figure Snap to each of the previously placed beams.
Revit may give you a prompt like the one shown above; simply click OK to ignore the warning. Once lowered, drag the end grip back, and then drag it to the adjacent beam again. This will cause Revit to properly connect to the adjacent beam and clean up the connection graphically. Remember, you can drag the grips to reposition the temporary dimensions so it goes from the beam to Grid 4. Draw the three remaining beams to support the floor opening: a.
Set the elevation i. Set the Structural Usage to Girder. Once the elevation is set properly, drag the beam endpoint to its support so it snaps to it. The Structural Usage determines the line weight of the line in Coarse mode. This setting also relates to structural analysis via the external programs that can import a Revit Structure model.
Notice, in this case, an angle is set to be a girder because it is holding up part of the floor, albeit a small portion with minimal load. F YI : It is possible to add a permanent dimension from the floor opening to the beam and then load the dimension. This would cause the beam to automatically move with the floor opening.
The curved beam is too long, so a column is required at the midpoint. Rather than trying to locate the grids and column first, you will place the beam first.
Then you can place the column centered on the beam, and place the grids based on the column location. Finally, you will split the beam at the new column location. This shows that things can typically be modeled in any order. There is not always one correct way to complete tasks.
Place the curved beam; see Figure Select the Beam tool. On the Ribbon, select the Arc icon identified.
