# Extract Mesh Part ## Extract Mesh Part The ExtractMeshPart command extracts all mesh faces radiating out from the selected face to unwelded, non-manifold, or naked edges in the parent mesh object. ### Command-line options The scriptable command, -ExtractMeshPart, provides extra options. ### **BorderOnly** Creates line segments from the boundary edges of the selected mesh face group.
### **MakeCopy** Duplicates the selected mesh face group instead of extracting it. ### **ExtractWholeDisjointParts** * **Yes:** Extracts the selected part in the mesh that does not physically join to other parts.
* **No:** The ExtractToNonManifoldEdges option decides how mesh faces are extracted. * **ExtractToNonManifoldEdges** **Yes:** Extraction stops at non-manifold edges. ![](https://docs.mcneel.com/rhino/8/help/en-us/image/topic_illustrations/extractmeshpart_extracttononmanifoldedges_yes.gif) **No:** Extraction stops at unwelded edges. ![](https://docs.mcneel.com/rhino/8/help/en-us/image/topic_illustrations/extractmeshpart_extracttononmanifoldedges_no.gif) ### **JoinOutput** Joins the extracted mesh faces into a 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.
