I put this in the parts section but it should probably behere instead... can someone help add these bend lines and fold thepart up..

Can someone help add these two bend lines, I cannot do it for somereason... it keeps telling me that i'm bending over other bendlines.

Additionally can someone tell how to take an initial drawing suchas a dxf make the internal bend lines for construction only inorder to create a base flange and then after the flange is createdto change those lines from construction lines to sketched bendlines.. thanks...SolidworksSheet Metal
