Snapping wall settings?

Hi all hope you can help me.

I made a Pillar wall mod, and im trying to get the walls to snap on top of eachother. but every ting i try it snap to the middle of the wall and not top.
Were or how can i set that?

If you made the model yourself be aware that its location in the scene is reflected when you import it.

You can either change it in the scene in your 3d modelling application and re-import or you can adjust it in the blueprint here:

If you wall isn’t the same height as a normal wall, you will need to change the snap point height here:
