Creating a Site: Creating a Topographic Subregion

Creating a Site: Creating a Topographic Subregion

1/7/10 2:45-3:30pm

In this exercise, you create a subregion (see subregion post) to define the layout of the access roads and parking area. Creating a subregion does not result in separate surfaces; it defines an area of the surface where you can apply a different set of properties, such as material.

Training File

• Click Open.
• In the left pane of the Open dialog, click Training Files, and open Imperial\RAC_CS_03_Subregion_i.rvt.

See the titled tutorial in Revit tutorials (under help menu) for illustrations.

Pick DWG geometry for the road and parking

1. Zoom in to the area of the roadway and parking, as shown.
2. Click Massing & Site tabModify Site panelSubregion.
4. Click Create Subregion Boundary tabDraw panel (Pick Lines).
5. In the drawing area, position the cursor over a magenta line. (The magenta lines depict the roadway and parking areas.)
   • Press Tab until the Status Bar indicates that a Chain of walls or lines is highlighted.
   • Click to select the chain of lines.
   Note: A chain is a series of lines or arc segments connected by their respective endpoints. You can use this technique to quickly select each of the chains of magenta lines.

   
   

   5. Using the same method, select all of the magenta lines.

   Draw lines to complete the boundary

   6. Click Create Subregion Boundary tabDraw panel (Line).
   7. On the Options Bar, clear Chain. The boundary must be a closed loop. Use the draw option to close the subregion at the 2 roadways.
      
      

      Note: Clear the Chain option to draw individual line segments. Select the Chain option to draw a series of lines or arcs connected at their endpoints.
   8. Draw a line to close the boundary where the left roadway intersects the site boundary. Click the intersection of the road and site line on the left. Move the cursor horizontally, and click the intersection of the line on the right, as shown.
   9. Using the same method, draw a line across the roadway on the right to close the boundary.
   10. Press Esc.

Change the material of the subregion

11. Click Create Subregion Boundary tabElement panelSubregion Properties.
12. In the Properties dialog, under Materials and Finishes, for Material, click .
13. In the Materials dialog, scroll and select Site - Asphalt.
14. Click OK twice.
15. Click Create Subregion Boundary tabSubregion panelFinish Subregion.
16. On the Quick Access toolbar, click (Default 3D). Close the file with or without saving it.
