Question

Creo 12, new problem when changing the curve contour

Hello Creo 12 users,


I’ve recently been having a problem with creating curves.


When I go to Options for the curves and adjust the points, the curve jumps back to a different shape after I click OK.  It looks as though the points aren’t being saved.


I’ve attached a video.

Does anyone recognise this problem and have a solution?

Thanks and best regards,

Hello Community,
Just a quick update.

At first, we updated Creo last month from Creo 8 to Creo 12.

I’ve discovered that the problem only occurs with curves created in Creo 12.

If I open an old Creo 8 model and redefine a curve, there are no issues. However, if I create a new curve in the old Creo 8 model using Creo 12, the problem arises.


The same applies to Creo 8 models that I’ve saved under a new name. Redefining (Creo 8) curves works fine, but creating new (Creo 12) curves causes problems.

 

Best regards

I think you should file a case with ptc and report as a bug.

      We had a very similar (probably the same issue) with Creo Parametric 12. The user ended up creating the curve with some other methods. I never did open a case but should have.
