Hello everyone! I'm a noob, but who wants to learn!
I made a small simple assembly that generates a low-poly house. Everything is going well, but at the stage when I wanted to place the windows, I encountered a difficulty. The thing is that my points, by which I want to place the windows, do not have normals. The "Normal" node does not help, since the attribute is created, but there is no display. Therefore, my "windows" (because for now it is a box) do not rotate along the walls of my house. How can I set the correct rotation of the window object by my points?
(In general, you need to randomly select windows from the collection, but apparently this will be a "for each" cycle ...) And why do my points not want to connect into a polygon? Once again, I apologize, this is my first week in Houdini.

By the way, I was able to implement a similar task in geo-nodes in Blender, if this will clarify my task better, I can also attach a .blend file. I just don't have enough understanding of some processes in Houdini yet...

UPD.

Well, as I said, I'm just a Noob. At the moment I solved the problem, maybe incorrectly, but it was solved). So, the fixes that I needed - Assign Normals after the subdivide node. Then use the promote attribute to transfer the normal information from the vertices to the points, and Wow! Everything worked, and did not even require additional movements. Well, I solved this issue on my own, but I think there are a lot of questions ahead)
