Terrain Is not cutting

[Steve_Nyhof]

Anyone want to take a stab at why the foundation is not cutting out the terrain? I am able to make a terrain feature and cut it, and I just found out because of the 12" drop in the gold room that it did funny things to the foundation bottom. But I change the depth to the bottom of the main footings and it works, but I feel like I have something disconnected.

Thank you!

I can't help with your problem sorry i tried but no luck, but I had a thought when sharing file on chief talk for help I would export disconnected plan file it is way smaller

Chief is getting confused by your foundation (for some reason probably related to your walls).  If you select the terrain, and use the "make terrain holes around building" tool, you will see the hole that it is using.  This hole has holes in it which is why you can still see the terrain inside the building. 

 

 

 

So one way to solve this is to turn off "hide terrain intersected by building", select the exterior room by clicking on an exterior wall and using next, and then use the "make room polyline" tool, and then convert it into a terrain feature, and then make it a hole.  You could also just edit the polyline made by the make terrain hole tool or draw it yourself manually.  Since your building shape was complicated enough I think auto generating the polyline from the exterior room was a good shortcut.

 

 

 

Not sure what that flag pole is btw.  It looks like it might be coming from a bad wall connection which may or may not have anything to do with the terrain hole problem. You might want to see if you can figure that one out and if not someone might be able to help.

Thank guys for trying. I think it is either that "flag pole" or the golf room dropped below the basement floor

I did this and it does work, but by default the holes depth goes down to the golf room footings which something funny on the main foundation outer footings. So when I make the whole the depth of the main footings it is better, but still shows some dark spaces under the footings.

 

I got it working good enough. Thank you again

See if that works I turned off furred walls and turn room definition on I have notice furred walls giving trouble.

Here's the problem: the small room divider walls that separate the wall types at the window wells. Delete this and it works correctly. Of course, you'll need to figure out another method to control those walls.

Hi Rob. I'm not saying that there is a problem with the pony wall, but I have used these pony walls like this for years now without an issue. I think the golf room may be more of an issue, and possibly the firr walls, but they have not giving an issue either for years. Once I get back to the plan, I will put the golf room back to the normal floor and test that. I also think the window well itself so close to the side of the wall in that spot may also be "part" of the issue.

Thats it. I added a wall divider to stop the pony wall. Thank you!

Great job trouble shooting
