Hi everyone, I’m trying to set the orientation of my families on walls, but I can’t find any node that allows me to set them to be parallel or perpendicular. I want the families to always be parallel to the wall they’re placed on, regardless of the wall’s orientation. Is there a node that can achieve this? ---

isn’t it the default behavior of some wall-based families? ---

Yes, but my problem is that I want to simulate wall openings with my families. Once I run my Dynamo scripts, my instances are placed and scaled correctly, but orientation is not right. On two walls, everything is perfect, but on other two walls, instances are wrongly rotated. All of my placed families are looking in the same direction, regardless of the wall they are on. ---

Hi @lovro.sibenik could you show your graph ? and share that family, is it workplane based or face based, or host based [door etc] ---

[LS\_dynamo1.7z](https://forum.dynamobim.com/uploads/short-url/8dszZmc3hFJyp9lx0UyST8SiWuf.7z) (2.9 MB) This are the family instances that I use + my Dynamo block diagram. ---

here is a fast example you could play around with ![FK5zS5GYcs](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/b/9/b9436d35fce2a10c15c38d472a5866a73901a23e.gif) ---

I mean this is good for placing one instance at a time, but my goal is to place all instances at once. When I start the program, it should find the places where instances should be and rotate it correctly. ---

you will just need find out which wall the family belong to, can be done with does it intersect node so try play with that ![Revit_WdKkNdH1e9](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/2/d/2d2f6987634e06bc8ed933f8cd0424add392c5ac.gif)
