Surface Modeling

Surface modeling tools help with thin geometry, open forms, and workflows where you need face-level control before closing or thickening the result.

Start with Create Surfaces for surface-generation features such as Extrude, Revolve, Loft, Sweep, and Blend. Use Modify Surfaces for face-level editing such as Split, Flip Surface, Join, and Delete Face. For surface-orientation display settings, see Back-Face Color for Surfaces in Workspace Settings.
