How to rotate placed family instances around project base point and z vector

Revit

Hi guys,
I need to rotate some of the placed family instances around the project base point (my project base point and survey point are not at same location).

Is there any node that I can use to rotate the placed family instances around project base point by angle equal to value in “Angle to true north” parameter?

thanks in advance

the Rotate Family node in archilab can do that

Thanks for the reply.

But I have one query. Around which point it will rotate the family instances as I am not seeing the point of rotation in the node.

I tried the script as shown in the image but didn’t got any result.

I am using:
Dynamo version 1.3.4
Revit 2017
archi-lab.net 2018.0.7 package for “rotate family” node.

Can you try the FamilyInstance.SetRotation node?

Well the FamilyInstance.SetRotation node only works when you need to rotate from an angle to a specified amount of degrees, so if you need to rotate a family 90 degrees from the already present rotation the FI.SR node will just set 90 degrees from (in example) the x-axis.
