# By Area ## Extract Mesh Faces By Area The ExtractMeshFacesByArea command separates mesh faces that are within a specified range of area from the parent mesh object.\ ![](https://docs.mcneel.com/rhino/8/help/en-us/image/topic_illustrations/stlrepair_083.png) ### Extract mesh faces by area options **Select faces larger than:** Selects mesh faces with an area larger than the specified setting. **Select smallest face:** Select a mesh face to set the area of the smallest face. **Select faces smaller than:** Selects mesh faces with an area smaller than the specified setting. * **Select largest face:** Select a mesh face to set the area of the largest face. **Increment:** Sets the amount the value is changed with each arrow click. **Select range from face:** Select an example mesh face to set the size range. A range of ±10% of the area of the selected face is used. **Border only:** Makes polylines out of the edges of the selected mesh faces instead of extracting them from the parent mesh object. **Extract a copy:** Makes a copy of the selected mesh faces rather than extracting them from 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.
