Hello to All.
I am involved in a project where I create design files in Rhino 5 and then send the files to an eyewear manufacturer in Italy. The manufacturer uses ProE (now CREO) as their manufacturing software. Sending my files to them requires that I export the files as either .stp (their preference) or .igs files.
I recently sent them a file where I had carefully rounded edges where “perpendicular” surfaces met. I rounded the edges by using the “pipe” command, splitting the surfaces using the pipes, drawing arcs perpendicular to the remaining surface edges, and creating the rounded surfaces using the curve network command (curve network allowed greater control of the surface than the sweep two rails command, IIRC).
Before I exported my files as both .stp and .igs files I carefully analyzed them for bad objects/surfaces and naked edges. The analyses indicated the models were good.
Yesterday I was told that the rounded edges (the “rounds” as they are called in ProE/CREO) were unusable when the files were opened in ProE. I was asked to rebuild the designs with square edges so the rounding could be done by the manufacturer.
Is their a “general set” of “best practices” that will ensure success when Rhino-developed files are exported as .stp/.igs files and then opened in ProE/CREO? I want to be able to send the manufacturer “good files” that they can use immediately. I am aware that this may simply be a problem encountered when exporting files as .stp/.igs file types. If there is a way to eliminate these difficulties I would like to know how to do it.
Thank you in advance for your courtesy!
