The Separate feature separates polygon shells within a polygon mesh into their own separate meshes. You can separate all of the shells at once or specify that only some of the shells get separated by selecting some faces on those shells.

To separate shells into separate meshes

1. Do one of the following:
   • Select the mesh object and choose Mesh > Separate.

   The shells are divided into separate meshes.

   • Select some faces on the shells you want to have separated and then choose Mesh > Extract.

   Only the shells with the selected faces will be separated into their own separate mesh. Any remaining shells will not be affected.
