Lock the components in place and use the transform tool to slide them into position. You can then use the link tool to combine them into one model.

How do you place the walls next to each other before you combine them? They are constantly bouncing off each other and lent whenever. If you use rmb to press it to the ground then grid stops working.

Idk how reasonable this would be, but adding some of the sector mechanicus parts would be awesome.

Thanks for adding this!

Mod now updated to include Administratum tiles as well!
