When trying to remove AutoCAD drawing objects using the Erase command, the surface does not reflect the change.
To delete drawing objects from a surface definition
- In the Prospector tab, right-click the surface to be modified. Click Properties.
- In the Definition tab, under Operation Type, clear the Drawing Objects check box, or you can right-click Drawing Objects and click Remove From Definition.
- When prompted to rebuild the surface, click Yes.
The drawing objects are removed from the surface definition, and the surface is automatically updated.
