Assembly constraining - Move part to bottom of tree

[RH_10122575]

When editing or creating an assembly it is annoying that when you edit the definition you have to have it below everything that you may want to constrain it with. Is there a way to disable it or when you select edit definition it automatically moves it to the end of the tree. No

It is possible to move some features to the footer in an assembly. I do not think it is feasible to automatically place an assembly component in the footer by default when editing references as this would cause parent/child reference conflicts in some cases.

Creo is a history based so it follows that you can only reference items that exist prior to a component in an assembly constraint context.

To add to what @tbraxton said:

Basically, no. If you are editing the mating definition of a component, and need to reference items lower in the model tree, you will need to move the component to be below the items.

This is just how Creo works. It solves the model by going down the structure in order. Creo is very rigid in this, but the benefit is more stability in the models.
