# Chamfer ##

Chamfer The ChamferSrf command creates a ruled surface as a bevel between two input surface edges.

### **Steps** 1. Select the first surface. Click the surface at the side you want to keep after chamfering.
2. Select the second surface. Click the surface at the side you want to keep after chamfering. ### Command-line options **Distances**: The distance from the intersection of the surfaces to the edge of the chamfer. **Extend**: When one input surface is longer than the other, the chamfer surface is extended on the longer edge.

**Trim** * **Yes**: Trims the original surfaces to the intersections with the resulting surface. * **No**: Does not trim. Uses the output surface to trim the input surfaces when possible. History is supported when the Trim=No. * **Split**: Splits the original surfaces at the resulting surface edges.
