Thickness Detection
When you convert a part to sheet metal, you are now prompted to select a base face. This pick allows Inventor to measure the material thickness for you. After you select a face, the Sheet Metal Defaults dialog box appears. The measured thickness is displayed in the Thickness value box. Click OK to accept the measured thickness value.

Export DWG and DXF
Some shop tools were unable to use an exported DWG or DXF flat pattern file if a bend centerline crossed a hole in the bend. A new option is added to the Geometry tab in the Flat Pattern DXF or DWG Export Options dialog box. Check the new Trim Centerlines at Contour option in the Geometry tab to trim bend centerlines to the edge of the cut.
