maybe someone can help me out with this problem...
I created a shapefile with circles (variing in diameter since they represent tree stems). For my hydronumerical simulations I want to "punch" them out from an existing mesh. I use triangular shapes for the mesh. That is why I need to change the circle shape to octagon so that triangels can be generated around the "hole". Is there a function in ArcMap or even AutoCad to change the shape automatically?
Thanks for any suggestions!
