Creating a Site: Adding a Building Pad

Creating a Site: Adding a Building Pad

1/7/10 4:00-4:30pm

In this exercise, you create a building pad. A building pad is a toposurface-hosted element and can only be added to a topographic surface. When you add a building pad, either the pad will cut into the toposurface or the toposurface will be built up, as required by the placement of the pad object.

Training File - In the left pane of the Open dialog, click Training Files, and open Imperial\RAC_CS_04_Building_Pad_i.rvt.

Add a building pad to the project

1. In the Project Browser, under Floor Plans, double-click Site.
2. Zoom in to the building footprint.
3. Click Massing & Site tabModel Site panelBuilding Pad. Note: By default, the Pick Walls command is active. If you have an existing building model, you can pick the exterior walls to define the building pad.
4. Click Create Pad Boundary tabDraw panel (Pick Lines). You use the DWG information to establish the boundary of the pad object.
5. Select all of the lines representing the extents of the building. (These are the dark blue lines including the small square representing the pavilion.) Optionally, position the cursor over a line, press Tab until the Status Bar indicates that a chain of lines is highlighted, and click to select it. The lines change color when you select them.
6. Click Create Pad Boundary tabSelection panelModify.
7. Click Create Pad Boundary tabEdit panelSplit. Note: You use the Split and Trim tools to modify the lines to get a closed loop boundary. When drawing in Revit Architecture, it is important that boundaries are established as closed loops with no intersecting lines.
8. Click the right vertical line of the building where it attaches to the pavilion, as shown. (The exact location of the split is not important, as long as it is between the lines of the pavilion edge.) The split command is similar to the break command in autocad.
9. Click Create Pad Boundary tabEdit panelTrim.
10. Select the lines (as shown in the tutorial graphic) to trim the boundary: (make sure you click the part of the element that you want to retain.)
    • Vertical building line above the split.
    • Top horizontal line of the pavilion
    • Vertical building line below the split
    • Bottom horizontal line of the pavilion
11. Click Create Pad Boundary tabBuilding Pad panelFinish Building Pad.
12. Click View tabCreate panel3D View drop-downDefault 3D.
13. Finished, close file and go on to next tutorial. Don't save in case you would like to revisit this tutorial in the future.
