@gkhalifah , check out topics like this [image] Place family instance to be perpendicular to one point Revit [capture] Hey guys, i tried to use your method, but somehow i found easier way. I found the perpendicular plane using nodes in the pic. and placed profile using…

I saw this topic, actually I want a node can I use it to rotate the family because when I used “family instance set rotation” a warning message show, I find the angle of rotation but what is the node to rotate.

@gkhalifah , can you set it there? [grafik] KR Andreas

I will check actually I thought no isn’t, but does a relation between them?

An adaptive family can be transformed in any direction by building the desired coordinatesystem. example [image]

so, I should find the coordinate system at each placement point then I can rotate the family according to angle, vector, origin? then feed it to “familyinstance.transform” yes?

Right, you get the “before” CS, build a “after” CS and then transform the family from one to the other. In my experience such rotations will often mess up the basepoint of the family, so maybe as a last step you will have to translate the family back in place. edit: oh, you can not use the familyi…

thank you so much bro, I will check it.

Step 1 is to identify how you would do this in the user interface. If you want “perpendicular to the alignment” you likely should be in the massing environment or the adaptive family environment and not a project environment. You aren’t just picking a point in space, but picking a point on a curve …
