A broken-out section is part of an existing drawing view, not a separate view. A closed profile, usually a spline, defines the broken-out section. Material is removed to a specified depth to expose inner details. Specify the depth by setting a number or by selecting geometry in a drawing view.
You cannot create a broken-out section on a detail, section, or alternate position view. If you create a broken-out section on an exploded view, the view is no longer exploded.
To create a broken-out section:
Click Broken-out Section
on the Drawing toolbar, or click Insert,
Drawing View, Broken-out
Section.
The pointer changes to

than a spline, create and select a closed profile before

tool.

drawing view mode to select an obscured edge for the depth of a broken-out
section view.
Click OK
