Rotating the multiple elements against one point

Hi everyone, I have just started with Dynamo. I got stuck with trying to rotate multiple elements (group of generic model families) against one point in plan, let’s say Project Base Point. It seems to be very simple operation then doing it manually in Revit. Just wondering if anyone could give some clue or direction. Many thanks in advance.

Hi @Kulkul,
Now it works for me. I really need to get used contextual help when you pointing on nodes. Thanks a lot for your help. Much appreciated.

Please mark the post as solved. You’re welcome!

@Kulkul What if i want the elements to rotate at their individual coordinate?
