Avoiding selected surfaces while surface milling

Avoiding selected surfaces while surface milling

Hello all,

I was wondering if anyone could give me a tip on creating milling windows
that avoid selected surfaces on large contoured nests. Currently we create
our milling windows using the sketcher. We chain all the boundary edges of
all the smaller surfaces inside the nest and then chain the outer part
boundary. This tells the tool to avoid the smaller island surfaces inside
the nest. This time consuming picking process gets worse with import
geometry. ProE overlaps lines and leaves tiny gaps between lines...etc.
Closing these loops sometimes takes hours. I've noticed when creating a
Machine Window that you can Specify Geometry Type for Mill Window with
Quilt-Collect only quilt geometry inside the window contour. Is it possible
to create a mill surface (quilt) and then create a mill window: silhouette >
and then change the Geometry Type to "quilt" so that the tool avoids the
quilt? I can't get it to work. Or is there a better way to do this?
Thanks for your help.
