I feel like we're always asking simple questions here, but we're stumped. We've done this process before so I'm not seeing where the issue is coming from, but we're getting errors when trying to make a closed corner between a mitred flange and an edge flange (we also tried it using both as edge flanges but got the same errors).
Is there something we've missed or done funny that's causing this? It says to try using the trim side bend option on the one of the flanges, which I'm assuming is the checkbox when creating an edge flange that asks to trim side bends? If so, when we try to select that then the edge flange says it's unable to create the edge flange.
Thanks in advance for any help, we really appreciate it!
