Hi, how can i find the lines that are not in a closed loop for sections? I have used pro desktop where you could 'fill' the sketch allowing you to see when the loop was broken. I could also choose supress when an error occured which highlighted the line that was causing the problem. I would like to have something in pro/e which means i don;t have to zoom in on every single join for every single line i want in teh section. Thx.
