Sketcher constraints not maintained when using relation to drive a sketch

[tbraxton]

Creo 7 (yes, I know it is unsupported).  This issue has had me waste a couple of hours already and I am stumped. Model enclosed for review.

I have a trivial sketch that is not correctly constrained when using a relation to control a sketch which is a parent of said constrained sketch.

First sketch serves as parent of sketch 2

Sketch 2 

Video showing that when driving sketch 1 using a relation to drive dimension d10 in sketch 1 the constraints in sketch 2 are not maintained correctly.

Anyone have any insight into why?

Hi,

I cannot reproduce the problem in Creo 7.0.11.0. Please watch uploaded video.

@MartinHanak & @kdirth Thx for testing this. I am using 7.0.12.0 so unless it is build date specific, I am still at a loss to explain it. I will try to reproduce this error again in Creo 7. I did test it in Creo 9 and the problem did not present itself.

I also have not been able to reproduce the issue with 7.0.11.0 or Creo+ 12.3.0.1-001.

I just opened a saved version of the model I posted for this thread in 7.0.12.0 and the erratic behavior does not present itself. It is likely something unique to the session I had open, and I have no idea how to reproduce it. One can clearly see in the posted video that the constraints were not maintained but it will likely remain a mystery.
