Hi everyone, I know this is an older thread, but I'm new to sheet metal... I just spent most of an afternoon trying to figure out the convert to sheet metal tool using an octagon to square lofted part. Out of about 10 designs, I finally created one successful example after reading your posts. Now I am trying to replicate it and I can't get it to work again. No idea why, I thought I figured it out with your posts and examples and now I feel like I am back to square one. It wont even allow me to select a surface as a tab other than the sketch faces. What should I be looking for? Thanks.
