Conical Roll Bending Inputs
You can manually assign 3- or 4-roll bending to conical geometry within the following guidelines:
The cone must be a portion of a cone or a full cone with a slit.
aPriori does not support 360 degree cones or cones without a small slit due to blank /sheet recognition  
aPriori does not definitively recognize a “Conical GCD”. Instead, the GCD is a Form with “Ruled” = true. The following screenshot shows an example of the Geometric Cost Driver panel for a conical part.
Various cone properties are estimated based on form dimensions, with PSOs provided to override defaults.
