Creating Solids from Enclosed Cavities

You can create a solid from a cavity by merging coincident surface or solid bodies in a part, and then removing the geometry defined by the bodies that enclose the cavity.

To create a solid from a cavity in a part with two coincident bodies that enclose the cavity:

1. With the part open, click Insert > Features > Intersect .
2. For Solids, Surfaces, or Planes, select the two coincident bodies that enclose the cavity.
3. Click Intersect.
   The three regions you can exclude from the final result appear in the graphics area and are listed in Regions to Exclude under Region List.

   This operation results in three regions when you select two coincident bodies that enclose a cavity, such as the bodies that form a mold part. The number of regions depends on the bodies you select.
4. Click Select All , and clear Region 2, the region for the cavity.
   Check the result in the graphics area to be sure that you are including only the cavity.
5. Click .
