Issue with Creo and features failing.

I had a model built years ago, and went to modify it in Creo.....and the trajectory completely failed, for no reason.  Segments were just missing.  Really weird.  It was a trajectory created by the intersection of 2 surfaces.  I changed the model to absolute accuracy and cranked that up, but nada.  Then, I simply recreated the curve in Creo and it worked.

 

Be aware then that certain models may have built in timebombs like this in them.  Thankfully this was actually a simple model, not one with hundreds or thousands of features (like I've dealt with before).  I'm going to do a test later to see if the same model works just fine in WF4.  I'm sure it will, but I'm goint to try just to rule that out.  If it does work fine, and I have no reason to believe it won't, it'll be yet another reason for me to stay on WF4.

 

I probably posted this once before, but I've read several places that your start models should be completely created from scratch every major revision (i.e. to WF, and now to Creo), otherwise these timebombs can exist in all your models built from an old start part used in a new release.

    Pretty interesting observation. I use WF5 start parts, assemblies and formats in Creo 1.0 and it behaves unexpectably sometimes.

     

    I know 3 sure ways to crash Creo 1.0 M020 at the moment.

        I have problem with importing CAD models from other CADs or universal formats to my templates.

         

        And also with most of the operations I perform on imported models like Remove feature. It sometimes fails for no reason and when I check whats wrong with the feature theres nothing wrong and after I confirm again it regens.

         

        So much fun when I got about hundred Remove features in a model.

         

        Btw 2000i sounds like a dinosaur jk jk

            I don't like WF5 interface and hate Creo 1.0 interface as well.

             

            I've read somewhere that on v17 or v18 or some sort of version like that (that old). When you were creating an edge radii you had to make sure about the right order of picking the  faces between which you were gonna create the radii surface. If you took the wrong order then the regeneration of that feature was like WAAAAY longer than when picking the opposite order.

             

            Had to be a pain to model anything parametric ways back then.

             

            I think it still is pain if you use WF5 or older version of Pro/E. Without FMX.
