When I create a part in a flat view and extrude the part as sheet metal for bending purposes, I then bend the piece part at the bend lines once the line have been converted. SolidWorks will form the part as desired. When I flatten the part out it appears with the dashed bend lines along with the outside of the radius in solid black lines which cannot be removed. After returning to the formed view, I try to save the part in its formed view and will not save the part. In addition to that problem we run a program called ProNest so the part can be cut out in the flat pattern and can take a formed part and transfer it into a flat pattern for cutting. Because the part can not produce a flat pattern in the part itself, it will not work on the ProNest program, the program is associated to SolidWorks 2013. I believe the problem lies within the sheet metal bending portion of the program. Would it be wise to reinstall SolidWorks 2013 to see if it would correct the corrupt file or missing files. SolidWorks 2013 was installed on my computer with SolidWorks 11 & 12 already existing at the time. SolidWorks 2011 & 2012 have been uninstalled since. Any suggestions will be greatly appreciated!
