I don't understand Blender... (snapping issues + more)

Hi.

Perhaps you can enlighten me as to how Blender… works… because it is not intuitive to me. I’m assuming the fault is my own. I’m trying to build a basic wooden ramp, but after four attempts I’ve about given up.

  1. How do I simplify the geometry when I have intersecting faces? I don’t want the mesh to go through itself here.

  1. Why does Blender not snap transforms to the grid when snapping is enabled? I couldn’t figure this out and while moving it did move it one grid length… it was still not actually aligned with the grid. I solved it by halfing the grid size…

  1. Why does Blender not snap my ring cut?

Uee boolean or knife tool or intersect tool. You have to do the work, no one button ‘fix’

    Set the snapping option to absolute grid snapping https://www.youtube.com/watch?v=TbjQY9-Iy1k

Thanks. But I can’t figure it out. Knife seems to delete the face and but an edge in random places.

Blue is what I’m looking for. Red is undesired edges.

Oh, and absolute grid snapping did not affect the ring cut positioning.
