Thicken a surface

Thicken cannot remove a face, so the maximum offset value is set at the distance where a face disappears.

1. In the Design workspace, Solid tab, select Create > Thicken.
2. In the Thicken dialog, deselect Chain Selection only if you want to select specific faces or surfaces.
3. Select a face or faces.
4. Use the manipulator or enter a value for the thickness (positive values thicken the exterior surface, and negative ones thicken the interior surface).
5. Select OK.
