Would advise anyone looking to nest parts with BOBCAD to look elsewhere. It is incapable of bridging parts together or common line cutting. There are better packages out there for the same price range which do this. Let my mistake be your gain. Look as NestCam and Cutleader ( I have both now after the BOBCAD debacle). They will overpromise what their software does and refuse to refund your purchase. An awful company and a stunted featureless nesting program. STAY AWAY.
