A sheetmetal expert can perhaps understand immediately what's happening just by looking at the image.
Is it possible to attach the sheetmetal part to troubleshoot the problem ?
I need to change the bend radius but I can't, software not allowed to change the bend radius but I can change the bend radius by recreating the flange alone
If you click on the Bend Options on the Command Bar, what do your settings look like.
first of all I would recomment and ask to use the username syntax together with the "@" sign, since this notifications inform the mentioned used about a direct concern, which makes it easier to answer as soon as possible.
OK, but the next irritates me, the bend radius in YOur example file already is 0.38"
sorry for not looking exactly.
And Yes this part seems to be destroyed somehow.
What I have done, was, to copy one chained face set from Your original, deleted the body and saved this surface as parasolid.
Just opend that parasolid again as new PSM, did a Thicken Body with 0.038" and convert it to sheet metal.
This now seems to be OK again and You can change anything You like (hope so)
The reason for that defect PSM body?
Don't ask me, but You should send it to GTAC for further analysis.
Hope it helps!
