To Specify Vertex Settings for a Roof Line or Floor Line

Use this procedure to perform the following tasks:

• Add, move, or remove vertices in the roof line or the floor line of a curtain wall.
• Add gables or steps to a roof line or steps to a floor line that was previously edited by adding vertices that define these conditions.

1. Select the curtain wall, and click Curtain Wall tab Modify panel Roof/Floor Line drop-down Roof/Floor Line Settings.
2. Select Edit Roof Line or Edit Floor Line.

   The active vertex in the illustration changes when you select a different line to edit. Any changes you make to the wall are reflected in the illustration.

3. Specify vertex settings:

   If you want to …	Then …
   add a vertex	click Insert Vertex. In the Wall Roof/Floor Line Vertex dialog box, specify the horizontal offset and vertical offset for the new vertex, specify a distance, and click OK.
   move a vertex	select a vertex from the list, and then click Edit Vertex.
   delete a vertex	select a vertex from the list, and then click Delete Vertex. The selected vertex is deleted, and the line automatically connects the two adjacent vertices.

4. Specify the horizontal offset.

   The horizontal offset specifies the existing vertex from which to measure the placement of the next vertex and how far away from the existing vertex to place the new one. Distance is measured in the direction the curtain wall is drawn. You can enter a negative number to offset the vertex in the reverse direction.

5. Specify the vertical offset.

   The vertical offset specifies the location from which to measure the height of the next vertex and how far away from the existing location to place the new vertex. You can enter a negative number to offset the vertex toward the ground.

6. Click OK twice.
