How to move a cube on a plane I'm using blender 2.8 and my simple scenario is: a plane and a cube mesh.

I want to move the cube on the plane without using the G command on the Z axis of the cube mesh, because doing freehand it's not perfect.

What's the best practice using blender tools?

Thanks
Helpful tricks to use when moving/scaling/rotating an object: to move on two axes while scaling/moving/rotating press S/G/R then SHFT+(axis you don't want to transform on). This will allow you to move on, say both X+Y axes, but not the Z axis if you press G-SHFT+Z, or only scale on X and Z- S-SHFT+Y.
