I have seen this in many modelling programs but I think it would also be useful in the model editor to have a "centre and rest on ground" option in the Mesh->Transform drop down.

What do you guys think?

Can't you just Center the mesh, turn on Box information and translate y till the min y is 0? Its 2 steps.

How do I turn on Box Information?

Edit: Found it B button.

Thanks, fairly quick way to achieve the same thing.

This is what alignment is for. When placing an object in World Editor, set Align to "Align Y to top". Align is located right above the "Add Param" button.

To Esenthel, is Y alignment backwards? Shouldn't using "Align Y to bottom" make the bottom of the mesh align to the position?
