Hey Adrian, thanks a lot for your quick reply! What you’re describing is exactly what I initially wanted to add to my question. This was what I thought to be the most meaningful approach, however, I don’t get this to work either. It does do increments, but they are not on the grid exactly, even with ‘absolute grid snap’ on. Looks like even with ‘snap with active’, Blender is using the average location of vertices?
You might not see this if your cube has the standard size, could you please re-check with an arbitrarily sized cube?
