For me, the angle of the fold is the one that corresponds to the angle (red arrow on the piece). So here, still for me, the angle is 135°. It's a matter of complementary/additional angle angle, can we set it differently?
For me, the angle of the fold is the one that the material must travel between its initial position (flat) and its folded position, hence the 45°. I don't think we can set this up any differently.
Hello, I agree with @d.roger, we're talking about the angle at which you have to make a bend of 135, not that you need a remaining angle of 45, otherwise the folders have to do the math each time, between the remaining angle and the desired angle which is complicated for them and not necessarily the fastest! Personally I find it logical, easier the job of the production!
I'm in the process of switching from Topsolid to Solidworks and in Topsolid the angle setting was as I just explained. That's why I was a little troubled ;-).
If anyone ever knows a solution, I'm all for it. otherwise I'll have to get used to it...
