Hi!

I have done numerous sheet metal models, however sometimes I run into things I haven't done before.  I have a co-worker that uses AutoCAD Inventor and he has an elbow gore in dxf that he would like to roll to a 21" Radius. 

Is there any way for me to take the attached dxf file and roll it using SW, or do I need to model a gore segment and then trim to match the dxf file.

Thank you in advance,

John
