hi, I use trim a lot in rhino by extruding a curve into a pastry cutter and using it to cut the same shape out of a block that I have made with a textured surface.
I need a wide range of shapes with the same texture so i created something in grasshopper so that my original curve could be altered in rhino and the resulting trim would be ready to bake from grasshopper…this way I can get a lot of shapes quickly just by moving the curve points.
the problem is that if I don’t cap the extruded cutter I get the message “it is only possible to trim with closed breps”…despite the fact that the same cutting shape works properly if executed in rhino.
the consequence of capping is that I no longer have a pastry cutter but a punch and this leaves a hole in my solid instead of the shape of the curve.
can anyone help please…is there something that can convert the cutter extrusion into the correct brep so that I dont have to cap ?
