I have solid works 2017 and receive IGS files from a customer. I can not convert the parts to sheet metal, because there are too many faulty faces and gaps. the bend radii in the corners often overlap, even though the sides are separated by a gap. at Import diagnostics, I get "the indicated face pierces through the solid" error on 20 faces in this model. I am new to Solidworks - what is the best way to fix these corners? is there a fast way to fix them all at once? can I add a bend relief hole to a solid part?
