Hey Thomas, A while ago, you and Jelle were talking about creating an API for pythonOCC that would simplify and hide the ugly guts of OCC. I haven't seen too much on this front in a while, but a few days ago I was talking with Christian Siefkes, Ben Lipkowitz, and a few others about a potential look and feel for python that would hide away OCC, or even BRLCAD or anything else that we opt to throw under the hood.
I was wondering if I could get some thoughts on how this feels: http://designfiles.org/~bryan/csg.py sphere = Sphere(position=(0, 0, 0), radius="5 mm") base = Circle(diameter="20 mm", position=(0,0,0)) cylinder = base.extrude(length="10 mm", direction=Vector(0, 0, 1)) sphere.position = (0, 0, 10) lamp_post = cylinder.fuse(sphere) #if you're in an X11 opengl session thingy: display.add(lamp_post) #or if you want to export it: iges_data = lamp_post.to_iges() file_handler = open("lamp_post.iges", "w") file_handler.write(iges_data) file_handler.close() And maybe some parametric PAF stuff? base = Circle("base of base plate", diameter="20 mm") base_plate = Extrusion(base, "10mm", Vector(0,0,1)) #OR: base_plate = base.extrude("10 mm", Vector(0, 0, 1)) #OR: base_plate = extrude(base, "10 mm", Vector(0, 0, 1)) base_plate.name = "cylinder 1" assert base_plate == Cylinder("cylinder 1", diameter="20 mm", height="10 mm"), "Cylinder and base plate should be exactly the same" base_plate.diameter = "25 mm" assert base.diameter == "25 mm", "base diameter should have been updated" base.diameter = "32 mm" assert base_plate.diameter == "32 mm", "base plate diameter should have been updated" I am not entirely sure how to do this sort of feature tree. Any hints or advice from interested bystanders would be hawt. Also, I am sending this over to OpenSCAD because they have a similar thing going on, with their own parser, but nevertheless would probably be interested in python hooks and somehow influencing how those hooks feel & work.
