Hello, I'm very new to Houdini and I am learning for one of my projects for college. I am up to the point where I want to add a door onto my house and I have made a slider and such but I am not really sure how to orient it to the right direction on the wall rather than it sticking out and not rotating along the wall. Another thing I want to know is how do I make it so when the door and windows are overlapping, the door will replace the window and the window disappears???
