complex extrude cut help
(OP)
I will try to explain this as simple as possible. I am currently modeling a part from a 2-D legacy drawing. now my problem is that I have to create a cut into a flat face that is coincident to the front datum plane, with a perpendicular thickness of 5mm now the tricky part is that the back side of this block is at a 45 degree angle. Now I was thinking of doing a shell of the part but the problem is that the left and right ends of the cut are not constant... is there a way to create a variable thickness "shell" so that the sides of the shell can be a different thickness than the continual thickness of the shell.... hopefully I didn't butcher my question
thanks for the help
thanks for the help





RE: complex extrude cut help
Try this:
1) Select the back surface of the part
2) Offset this surface using Edit--> Offset so that the offset surface is "inside" the part.
3) Extrude your sketch, but under the depth option, choose "To Selected" or "To Surface" and pick the offset surface (one of the two should work)
Hope it works
RE: complex extrude cut help
You can define a non-default thickness to specific surfaces in a shell feature under the "References" tab in the Shell dashboard.. I forgot to add that to the last post.
But the Extrude to Surface method works when the side walls of the sketch are not parallel to the side of the part.

The Extrude will keep removing material until it hits the offset quilt.
RE: complex extrude cut help
Create the individual surfaces of each side, then merge the surfaces, then use quilt to cut the solid.
