To construct the walls, you simply extrude the floor plan polyline that you just imported.

Set up the scene:

• Continue from the previous lesson.

Extrude the polyline:

1. Click the polyline object to select it.
2. Go to the Modify panel. Choose Extrude from the Modifier drop-down list.
   TipWhile the Modifier list is open, you can press E a few times to find the Extrude modifier more quickly.
   
3. On the Extrude modifier's Parameters rollout, set the Amount to 8' 0”.

   3ds Max Design extrudes the polyline to create walls that are eight feet high.

   

Save the scene:

• Choose File Save As, and name the new scene my_wt_walls.max.
