Hello guys!

Firstly, I have an IF block that is “sorting” out if my electrical elements have 1 or 3 poles. I then want to place out different family, based on the number of poles. I thought I could do it like in the picture, but I guess I thought wrong…

 ![Example_eletrical](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/d/7/d759537587af7eb37bdd01bdfae95ae9c019530c.png)

Any ideas on how to accomplish this? I have tried a different kind of “use levels” in my list structure, but that did not seem to help.

For now the category is “Detail Items”, and the element is placed on a drafting view.

It appears that FamilyInstance.ByPointInView doesn’t support lists of views, only a single view. I’m currently trying to find a way around this, but I don’t know Python well enough.
