an align tool?

i want to align my vertices and things to the ground,
i always want to put the stuff sticking to the ground, but then the centerpoint is not on the base (under), so using the gobal co-orindates wouldn’t work.
i use rigid body for it, but it doesn’t work if i’m using animation

Do you mean something like snapping to faces/vertices?

You should know by now that support questions should be posted in the support forums not in the Blender Discussion forum. Please do so in the future or I won’t make the effort to move them, I’ll take the easier option and just delete them.
