I am having a problem with the contour roll feature. I am adding 3/8" ti a length of straight duct to make an egde. it works ok except that when I split the thing to length ( joins into a y connector). It will no longer unfold. also looking for the setting to get the flat patterns to match true length (see the unsuppress to unfold, while suppressing the first two features for the true length). On the contour roll suppressing the split will allow it to unfold. unfortunately that is useless to us.
I was able to add the two intersect and mine will also now unfold so thanks, any idea why this works, seems a bit like it should have worked without them. It's neat that you figured that out, no idea how, it is a bit mysterious.
