ChiefArchDavid Posted January 28, 2021 Share Posted January 28, 2021 (edited) Can you change a wall type from exterior to interior? I added a covered porch to my model with a safe room beneath, and grass is now growing in my safe room in the basement. It looks like the terrain builder thinks the safe room is external, and the program tries to put grass in there. The walls are all connected. I'm trying not to have to redraw the walls.

solver Posted January 28, 2021 Share Posted January 28, 2021 Make sure your safe room walls are all NOT marked No Room Definition. If that does not fix it, attach the plan. Link to comment Share on other sites More sharing options...
ChiefArchDavid Posted January 28, 2021 Author Share Posted January 28, 2021 I did a temporary solution by putting elevation points on the intruding landscape 6” below the basement floor. When I try to use an elevation region the intruding landscape just moves around the region, even if the region goes from wall to wall. I confirmed that “no room definition” was not checked. There is a railing on one side of the porch above with an arch beside it. I’m thinking that the railing is letting the terrain through. Link to comment Share on other sites More sharing options...

Rookie65 Posted January 28, 2021 Share Posted January 28, 2021 One of the things that happened in Pro 21 is that the terrain will not build under items that overhang the ground. Such as bump out fireplaces, bay windows, etc. What you do in those cases is go to Terrain>Terrain hole and draw a hole around the 1st floor area that you don't want grass in. Just draw it to the foundation line, not the framing. Then uncheck" hide terrain intersected by building" and that will get the grade to hit your foundation. It may not be the fix for this situation, yet probably something to keep in mind as you do more plans. Link to comment Share on other sites More sharing options...
