- Menu
This takes a selection of faces and solidifies them by extruding them uniformly to give volume to a non-manifold surface. This is also available as a Modifier. After using the tool, you can set the offset distance in the 调整上一步操作 panel.
- Thickness
- Amount to offset the newly created surface. Positive values offset the surface inward relative to the normals direction. Negative values offset outward.
