We are trying to cut an area out of a 3D drawing.....of contours.
AutoCAD is not liking this.
Can you please tell us if there is an easy way of doing this without AutoCAD hanging.
It needs to stay in 3D.
>> ....of contours
Are the geometry "contours" 2D-polylines or 3D-polylines or LW-polylines or lines or arcs or what type of geometry are these?
>> to cut an area
How is this area defined? Is it planar to world-coordinate-system or how is "area" defined?
If the command _TRIM does not help (estamated that you have only planar objects) then upload a drawing, that's the best way for us to see what you have, then we can give suggestions of how-to-do.
