I work with assemblies as much as I do individual parts so eventually, sometimes inevitably, I end up with rectangular or circular patterns of components. It would be great if the patterned instances of the parts were constrained to some geometry (ideally the source component) and have the pattern be editable to update those constraints.
The issue is when I place the first component and apply the appropriate joints, that doesn't carry through the pattern so all additional instances can be accidentally moved out of position. I can see some situations that may be preferred if you plan to rotate or apply new joints to the copies so maybe this could be added as an option to the dialog box. Personally I would like to have it remember my selection from the last pattern or be a global setting that I can select as a default preference and change only when necessary.
