FiGuRE 16.11 The exterior walls drawn with polysolids
Adding the interior Walls
The interior cabin walls are thinner than the exterior walls and will probably
have a different material assigned to them. You will make a new layer for these
walls and change the polysolid parameters.
1. Create a new layer called A-WALL-INTR-3DOB, assign it color 44, and
make it the current layer.
2. Click the upper corner of the ViewCube to change your view to a North
East orientation (see Figure 16.12), and zoom into the lower-left corner
of the cabin so that you can see the bathroom walls.
