Upload your plan it will get you a quicker solution and it will be better for people helping you. If it is to big compress, it or share with dropbox or others

Upload your file if you can't get it to work

Try opening railing wall, wall type on exterior layer and interior layer turn off framing see if that helps, things seem ok on my end but it has some strange rebates in the slab

Upload your chief file

Would wall material region tool help with this

Could you share your plan it would be easer to ell you what is wrong

Also the footing just turn it off under wall dialog foundation tab.

Forget dynamically just build terrain then turn of auto build terrain edit the retaining wall jobs is done, editing the retaining wall is a bit strange but it works, it seems like it is crossing over it’s self but ignore it as it does not seem to matter

Is that what you want

If you are still using retaining walls make sure the default top and bottom are selected as if you have adjusted the wall top or bottom chief will no longer auto adjust there top or bottom positions to match the terrain

Upload your plan so you will get best help

If you mix glens smart idea with Make roof base polyline it works with auto roof and you can loose the invisible walls

Give this a go your model is way of zero position see if it helps Shaw garage.zip

Sorry i missed that this is the way chief handles those roof situations I don't know why this happens, but it does happen it has been talked about on this forum but I don't know there is way to get auto roofs to handle it. What i do is start with auto roof and then do a manual edit at the end rooftest.plan

I downloaded you file and something funny is going on I will investigate

Open the room dialog and adjust rough ceiling height

What this video or use automatic roofs with setting correct ceiling heights

Some times with imported terrains you can get away mostly only using major contours that makes it easier for chief to handle

Have a look at this file see if it is any good, I reduce your sub facia and made your facia larger also a larger over hang on hip walls i added 1" 361955604_GambrelRoofShed Mark edit.plan

Image showing the result, I use a program called formZ that is like sketchup only a bit better i think and it can give you mesh volume and i wonder if it would work if the 2 meshes volumes where compared but never tried it.

I would make 2 terrains one would be existing then convert to symbol then edit existing to proposed and merge with symbol sometimes I give the symbol a semi transparent material so you can see through it in 3d

It sounds like you need to change the render setting in your viewer program

If you can upload your plan file compress if it is big or after compressing it, it is over 14mb dropbox or other cloud share
