3D polygons

Recommended Posts

Is there a way to trim, clip or subtract points from a 3D polygon or number of 3D polygons without deleting single points one at a time? Especially interesting if you want to make a rectangular terrain model from an irregular set of elevation curves (3D polygons)

Select Polyline>edit> Polyline> goto the OIP>select the starting vertex... then... > click on the "Delete Vertex" button ...

now .. depending on how many vertices you desire to delete... > place the appropriately weighted heavy object on the "return" key ... take an ergonomic break ... or ... go to lunch ...

upon returning... 'viola' all the nasties will be gone.
