I'm a new Blender user. I have a shape which is a cube section (I made it with the boolean modifier and two planes). Then, I set its origin on the center of one face, which I want to "glue" to another plane. I tried to use the snap tool, with the settings "face" and "center", checking the "align rotation to target" option.
As you can see on my screen, the mesh does snap, but with the wrong normal. In the end, the faces are not parallel to each other. Can you please help me? I've been wandering the internet for literally more than an hour.
