Can't orient Symbol to Family Instance

[luiza.longo]

Hello, I 'm new to the forum and I’m stuck with an issue on Dynamo.
I have been developing a dynamo definition to place symbols on top of family instances. I have been able to place them on the desired location, but I need them to align to where the instance is facing. The FamilyInstance.FacingOrientation Node doesn’t seem to be doing the trick.
When I run my definition, I get the result in the picture.

I need the symbol to be aligned to the speaker… I can’t seem to figure out how to do so. I have tried retrieving their reference planes and calculating the angle between their respective surface normals, and that was the closest I got to aligning both, but sometimes the symbols are flipped.
I would attach more files, but as a new member, I am still not allowed to do so.
Any help is welcome!
Thank you

You may can try comparing the vectors from the element’s transform to the view’s up direction and use the view direction as the rotation axis. Here is a snip from a script that I created that utilizes that for view rotation matching.

I was able to rotate all items properly using the up direction reference instead the way you suggested.
Thank you very much!
