If you did it correctly, you can now place walls without an error message or need of cfe.ĥ. Lower it only to the inner walls of the foundation so that the terrain on the outside is not affected.
Start at the lowered tile and draw the tool towards the foundation walls. Remove the stairs and use the terrain flatten tool to lower the ground in all of your basement. I usually do it in 3 sets of 4 steps as I cannot count to 12 :P (A regular wall is 16 steps high, a foundation is 4 steps high per default, so you need to lower the terrain 12 steps).Ĥ. Hold shift to control the number of stair steps. On the ground, use the stair tool to lower the terrain. Now make the foundation hollow where you want your basement to be leaving just the outer tile of it.Ģ) Make sure to switch off auto-roof and to remove all auto roofs.ģ. 1) First build a foundation with the foundation tool (NOT the basement tool!).
