Hi there Deniz!
I have finally figured it out! Your solution is perfect! The only thing thats missing is a rotation around the project origin, equal to the project rotation.
But is there a way/ node to rotate the inserted elements around the origin of the model, that can be at the end of the graph?
Instead of entering 0, can you enter the angle between true north?
Hi there again Deniz
Where do you want to enter “0”?
I havent defined the rotation anywhere?, only X,Y and Z for the point 
I’m also struggling with this. I can’t seem to figure out how to get it to work when the Angle to True North is not Zero.
Did you ever figure this out? The CoordinateSystem.Rotate node doesn’t seem to do anything for me.
Hi there @dfoth
Unfortunately not, I just ended up selecting all components, after Dynamo inserted them. Then rotated them around the project base point maually.
Then everything fitted 
I did the same thing as a temporary solution. Then after a lot of digging and testing I figured it out. I’ll post a solution soon. I don’t know exactly why its working, but it is! lol
Here’s the solution. You could refine it further to allow the user to specify what family they want to place.
Please mark as a solution if this works better. It worked for me.
