Delete 3D Surface

The individual surface of an object can be temporarily removed from any 3D view by selecting 3D> Delete Surface and then clicking on a surface.

Surfaces removed in one view are removed in all 3D views, but are not permanently removed from the model. Continue clicking surfaces to remove them, then select another tool when you are finished.

Hold the Alt key while clicking to delete one triangular face at a time rather than all adjacent surfaces. See "Render Panel".

Select 3D> Delete Surface or click the toolbar button to restore the most recently deleted surface. All surfaces can be restored by selecting Build> Floor> Rebuild Walls/Floors/Ceilings or by exiting the 3D view and reopening it.
