All I have drawn is a U shape sheet metal part from the online tutorial, I then added a tab one side then put a line across where the tab is to be folded. This is the point where the problem occurs I dimension the height from new scribed bend line to the top of the tab also dimension the bend line (although I don't think I need to) All looks ok but then I click on sketched bend, this then gives the notice that the dwg requires a fully defined dwg. Ikeep following the online tutorial word for word and still get stuck each time at this point. Really frustrated any further advice would be greatly apreciated. (using 2003 version with the tutorial ).
