Unroll a tube
Unroll a tube
(OP)
I have a tube with several holes drilled in it. Now the factory wants to make it out of sheet metal and roll it instead of buying tube. I tried to make a pattern by going back to the first sketch and keeping just the od. I put a small gap in it and then converted it to a base flange. Everything looks ok but the part cannot be flattened. Apparently SW wants flat surface for reference and does not recognize the round surface.
Is this even possible to do? I could just make a sketch and calculate the flattened dimensions if not.

RE: Unroll a tube
How did you "convert" to a base-flange from what it was? There may be an issue with the editing process. Does it work if the part is recreated from scratch?
RE: Unroll a tube
The sketch is just a circle with a gap in it. The diameter and the gap size are specified. The base flange feature calls for a bend radius so maybe that is the source of the problem. If the diameter of the part is specified, I'm not sure what they mean by bend radius.
RE: Unroll a tube
2) The bend radius (usually 1 x material thickness, depending on the fab shop) would be used if you added an Edge flange (or similar) to the gap edges, as though the material had actually been formed on a press. It does not refer to the radius you are using to create the split tube, that can be whatever you specify.
