Create a contour roll feature by revolving a profile consisting of lines, arcs, splines, and elliptical arcs.
A contour roll feature can be the base feature or a subsequent feature in your sheet metal part model.
To aid in the preparation of detail drawings, Contour Roll centerlines have a unique Object Type and are placed on a separate layer of the drawing.
Simple legacy rolls
In releases prior to Autodesk Inventor 2015, you can create simple cylindrical or conical rolls. When migrated to the current release, these types of rolls are not converted to Contour Roll features. They retain the attributes and behavior of previous releases.
