I inherited a messy cad dwg plan file exported from vectorworks which, when imported to rhino, imports everything on one layer and all the hatching is exploded. It’s a messy top view architectural plan of a house with backyard. It has many 2d bushes with thousands of leaves as tiny oblong closed curves and broken line hatching all over the drawing representing the various floor finishes inside and out. It’s nearly impossible to select these things without selecting the important elements like doors/walls/windows.
Since much of the hatching that I want to get rid of is either rounded closed curves (not square/straight curves) or diagonal hatching, is it possible to select and isolate just those elements?
