Question

Creo behaving badly with feature order when patterning

In the attached file, if you try to pattern Sketch2, Sketch3 is removed, as though Creo is taking you back to just after Sketch2 was created. This is no good, as I only made Sketch3 so I could use it as a direction for the pattern of Sketch2!

This is not the way for a parametric modeler to behave, and it's inconsistent. The Extrude feature doesn't cause it to jump back in time (thankfully). Can anyone help me out with getting it to do things properly?

Thanks

I don't have access to Creo 1 so can't open your file but from what I understand of how your features are ordered this is nothing new. If you are wanting to use something as a reference it needs to come before the feature that is going to reference it. If sketch3 doesn't reference sketch2 drag it before sketch2 and then try to pattern.

But I only want to use Sketch3 as a reference in the pattern, and the pattern comes after sketch3, so.. why isn't it letting me? I'm going to install WF5 to see if it's the same.

If sketch2 is ordered before skecth3 the pattern is going to come before sketch3 even though. The problem is sketch3 will become a parent for the pattern of sketch2. A parent reference has to come before a child reference.
