Creating Cut-outs in a Roof Face

Use the Clip Surface command to add a cut-out to a roof face. A cut-out, for example, can be used to add a hole for a chimney that overlaps two or more faces of the roof.

This procedure creates a cutout in a roof face created with the Roof Face command (see Creating Roof Faces).

The edges of the cut-out are mitered according to the selections made in the Create Roof dialog box during the creation of the roof face.

To add a cut-out to a roof face:

1.	Select the roof face.

2.	Create an object with the dimensions for the cut-out and place it where the cut-out will be located.

3.	Select both objects.

4.	Select Modify > Clip Surface.

This creates the cut-out in the roof face, leaving behind the object used to make the cut-out.

5.	Select the object used to make the cut-out and delete it.
