Bend Deviation PropertyManager with the loft sheet steel tools

When you create a lofted bend, you can examine the surface area and curve lengths of the bend. These items are located in the Bend Deviation PropertyManager.

To examine bend deviation:

1. In the FeatureManager design tree:

   1. Right-click Flat-Pattern1 and select Unsuppress.

   2. Click to expand Flat-Pattern1.

   3. Right-click Flatten-1, and select Bend Deviation.The graphics area callouts display the bend deviation values for each edge. The bend deviation plane for the Bend

Thanks
