Reload/Re-Import updated CAD Step file

tdorner
Hi everyone,

maybe it is a simple question but I need to make sure there is a better way to work with revisions on a CAD-model instead to re-write the whole program with every revision that is coming up.

My question: I have written and run a program in PC-DMIS 2014 based on a CAD-Model (let's say Rev. A). Now our customer made a change (Rev. B) to the part, respectively to the drawing/CAD-model. The existing program is pretty long. Is there a way to import the new Revision (Rev. B) of the CAD-model without loosing the existing work? Just add or delete the sections they are revised or new.

Hope anybody is able to help.

Thanks,
Thomas
  • File> Save As... New program name (part #_rev#)

    File>Import>(CAD type)... Say yes to view the two CAD on top of each other to view differences, or say no to replace the old CAD with the new.

    Make changes as necessary.

    Viola! Slight smile
  • Hm, I imported the new revision and said merge, but the part is somewhere in the area and is not on top of the exisiting one. Do you have any idea why?

    Either the CAD in your program was translated, or the CAD location changed during the revision. I'm guessing the former.

    If you go into Edit>Graphics Display Window>CAD Assembly, you can highlight either CAD and in the top left area, it will show you what offsets were used, if any.
  • Merge does not replace the current CAD, it adds the new one to the program... Maybe that's where it went wrong?

    There is an option available (I think it's part of PC-DMIS Planner) that is called Change Manager - after you have imported (and possibly translated) the new CAD file, you use it to automatically scan the whole program and list all features that do not have corresponding CAD features/positions. Then you can (still from this dialog) update the features you want and/or remove features that no longer exist in the model. It works very well in the demonstrations I've seen and in my own experiments (with faked changes). I have not tested it on a 'real' changed CAD, so I don't know what problems can turn up...
