edit family: align to the persian center.

[ossosso]

Hello.
attached I have inserted a .rfa file of revit, for the "persiane.rfa" that for other you can download from the site of the autodesk under the "italyext" extensions.

the Persian in question has its pivot (center) moved on the left side, so when I go to increase its width, the left side remains firm and right extends.

I would need the pivot from the left to be moved to the center of the Persian, so that when increasing the width extends in the same way to right and left.

How do you do that?
My notions of editing and creating families are a little limited and I can't.

Thank you very much.

that placed is a family whose origin is blocked on the center of the main floors (centre: front/back - center: left/right). the outer plan manages the stretching.
to have the family as you ask, they need two external floors (compared to the central ones) bound with a parameter of fairness (from the center), which determine the extremes of the frame.
I don't know if "rectifying" the family on the subject, everything works. test
