Note:
You can use this command to flatten a sheet metal part to a .PAR, .PSM, or a .DXF file. The bend lines are automatically created in a .DXF file.
The flattened part is not associative to the folded part. If you want to maintain associativity to the folded part, use the Part Copy command on the Insert menu or the Flatten command on the Simplify/Flatten toolbar.
The Save as Flat command does not automatically create bend lines. You can use the Insert Part Copy command to an insert a part copy into a sheet metal (.PSM) file if you want to display the bend lines in a drawing view.
You can use the Save as Flat DXF Options dialog box to define such things as the line type, line color, and layer display in the DXF file.
You can use the Flat Pattern Treatments page on the Solid Edge Options dialog box to specify if want to use the folded model or an existing flat pattern to define the flat pattern.
