# Extract Mesh Faces ## Extract Mesh Faces The ExtractMeshFaces command separates selected mesh faces from the parent mesh object. This command works best in shaded mode, because you can pick the shaded mesh faces as well as the face edges. ![](https://docs.mcneel.com/rhino/8/help/en-us/image/topic_illustrations/stlrepair_082.png) ### Command-line options MakeCopy * **Yes:** Makes a copy of the selected mesh faces rather than extracting them from the parent mesh object. * **No:** Extracts the mesh faces leaving a hole in the parent mesh object. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
