The 'Why is it floating?!' Problem in Blender — I Made a Free Add-on for That

Have you ever run into any of these situations in Blender?

You placed an object at Z = 0, but it's floating in the air (or half-buried in the floor)
An imported model has its origin at the mesh center instead of the bottom
You tried to move the origin to the bottom, and it took way more steps than it should

If the origin is at the bottom center, you can just snap it to Z = 0 and it sits perfectly on the floor.
But getting there requires a few annoying steps:

Switch to Edit Mode, select the bottom face/vertices, and snap the 3D Cursor there
Switch back to Object Mode and set the origin to the 3D Cursor

When you're building an interior scene with a bunch of furniture, doing this over and over gets old fast.

So I made an add-on that handles it with a right-click.

Origin to Bottom Center

A simple Blender add-on that automatically moves an object's origin to the center of its lowest point (bottom face).

Select multiple objects and it updates each one individually — no need to do them one by one.

When it comes in handy

Placing furniture and props
With the origin at the bottom, dropping something at Z = 0 places it perfectly on the floor. No manual height adjustment needed.
