Rotate Family instance in X or Y direction

[vipinkr]

Dear Sir,

Please help !

I am trying to place inline pump on the floor through dynamo.
I did the following, but unable to do. I know, there is something that I am missing because this may be very common in use.

1. I used FamilyInstance.ByPoint Node and then try to rotate it, but it is rotating only about the Z-Axis.
2. I used FamilyInstance.Byface by making foundation (cuboid) as face and surface normal as a reference direction, but Error (family placement type is not work placed based ) is showing.

Thanking you,

@vipinkr Show your complete graph with all the previews on.

@vipinkr use FamilyInstance.SetRotation node after Family.InstanceByPoint node to rotate.

[vipinkr]

I Think that is rotating about Z-Axis not about the X or Y axis

[vipinkr]

Have a look on the attached file, it is rotating about the Z-Axis, But not about the X or Y-Axis.

Hi every one ! Please help me.@kulkul

replace the “Vector.YAxis” with “Vector.XAxis” or “Vector.ZAxis” if you want to rotate it on a different axis

Hi vipinkr
you cant attain proper rotation of family element until you set the centro-id as location point.Hence try changing the location point as centro-id and then use rotate family node from Archilab package.
have a good day

Hi! I’m trying to do the same thing but having issues with the Rotate Family node giving me null. Even when I’m trying a script exactly like yours it’s still not working. Is this still working for you (if you’re still using this workprocess) or has the node broken in a Revit version? I’m using 2021.
