How to stop model from hovering? bounding box problem

Whenever I group my parts together the bounding box always seems to go deeper underneath when there’s no part underneath it. Is there anyway that I can fix this?

Edit: Changed from scripting support to building support.

There is one, take a part that is parallel to the floor or so and set it to the primary part Primary part is a property on the model. That should change the moving anchor point

Doesnt seem to work

While pressing alt hover below, is there a part?

If there isnt press “Crtl+L” does the orientation of the bound change?

There was and I lowered the platform a bit but that didn’t change anything. The orientation doesnt seem to change. No there is no invisible part underneath the model while pressing alt.

Have you tried to set the bottom part as the primary part? This usually fixes things. You can access it from the model’s property under “Pivot”.

I’ve tried setting that big part you see as the primary part which is underneath data

How big is the hitbox? Is it possible that this is what is causing the issue?

@ItsKoiske
No the problem was already there before I put the big hitbox that platform you see covering the model.

Could you share the model?

It sure looks like there’s some sort of invisible part underneath it. To double check, could you turn the Collisions toggle on and try dragging it down with the Move tool?

Here’s the model, let me know when you get a copy so that I can copylock it.

The roof wedge is to blame:

The bounding box of a Model is based off of the bounding boxes of the contents, not their actual physical collision geometry, which is why you see the issue.

Here’s a copy of the roof made using CSG instead to be in the correct orientation as a workaround: FixedRoof.rbxm (10.8 KB)
