how can you move curves?

I've imported a customer STEP model.  This model includes many curves that I need to move and re-position.

I have no issue selecting the quilt, points and datum planes but can't move the imported curves.

If I manually pick the curves I do not have the usual copy and paste dialog available.

If I filter pick I can't even select the imported curves.

Perhaps I could drop a CSYS in the end position on the customer model; export this model, and re-import the model in it's true position, but this most likely will make the geometry dirtier through the extra export and import.

Is there another way to move EVERYTHING in the customer model?
