Unequal Mitered Flanges in Sheet Metal

bill_daniels

Mitered flanges work great.   However, I have a requirement for mitered flanges on a box lid with 1" flanges on the sides and .75" flanges on the ends. 
I can't get this to work - any ideas?

please see if you can use this approach . First build the solid shape and then convert it into sheet metal in one step.

I couldn't get that to work.  Your example uses equal width flanges at 45 degrees.  I need unequal width - i.e. 1.5" on two sides and 1" on the other two.

See below. This is the best we could figure out for this. 1.88 flange going into a .625 flange at an odd angle. Hopefully Onshape improves this and comes up with a better way.
