I don't know shite about:

Stop falling through the floor in Blender

Move elements in blender only on the X and Y axis

Today I learned a simple but powerful trick to keep your restrict movement in blender. Imagine you want to move an object on a plane surface but blender keeps shoving your object "below the surface".

Ahhhrrgghh! Don't you hate that? 💩

You could move the object one by one on it's X and Y axis but that would be a bit tedious.

This is where restricted movement comes into play.

If you hold SHIFT while grabbing the blue Z axis, blender will only move your item on the remaining axis.🥳

Now it is impossible to move your object through the floor. ✅
