Here is a file with auto roof it may help you 1467467882_existing-dormer-fix(1)Mark.plan

Watch this you tube video

Have look at this plan i rebuilt the roof with some other changes noted in the plan, its like you have found a condition that is tricking chief 1467467882_existing-dormer-fix(1)Mark.plan

If understand set ceilings to 9’ and lower your roof planes to 60” and that should cut your walls down

if you give me a plan with your model i will put the terrain in it if you want i also had no end of trouble with the cad file i think it has something to do with the contour line being blocked not sure

upload your home designer file and i will have a go at it

I wonder if you use the room structure to set deck framing leave a airgap where roof components would be add a framing layer floor joist then manually draw roof plane in airgap and framing then convert framing and roof plane to a symbol as that will stop the roof plane messing with the structure

I was try to fix this while Eric was making his very helpful video here is my file if it helps Plan 1556 with porch (A).zip

I think you have unknowingly inserted a second floor delete that with your floor tools and thing should start working also you have lots of unconnected walls witch wont form rooms you need all rooms wall connected to form rooms hopefully this will work in your software as i am guessing you using home designer brand not chief architect as this forum is for

i think you have been using the eyedropper paint tool try changing the materials back the there defaults also remove the room wall coverings things should look better after that

use a terrain hole

Not sure but make sure your video card drivers are up to date

With that interior office that has a gap i dragged the lower wall to the ridge the the gap was gone give that a try

Have a look at the attached plan your exterior walls need to be setup like in real world also the interior layer is the main layer i reset the main layer so it has altered your exterior size so perhaps use your model and reset so you can see what is going on the gap on that interior wall not sure these guys here will know i am sure 1527905163_Testhouse mark change.plan

The bonus room walls are marked as no room definition turn that off

Try the terrain hole tool

plan attached should be fixed 951192931_RAILINGISSUE.plan

check second floor defaults ceiling heights the have negative height

to start with the deck has negative ceiling height check that try that but there is still some other problem

Double click the select tool

If you put the terrain on the floor below u should be able to have deck wall on top of terrain retaking wall I think

See if that is what you want you had your retaining wall on the floor below all terrain controlling data needs to be on same level as terrain perimeter but i shifted your deck wall a bit Plan mark adjust.zip

See if that is what u want 1194947785_428734283_Gableroofsforaddition(1).plan

Out of interest looking at the DTM layer are the intersections the points where the elevations where taken during the survey? yes i put those lines on chiefs elevation data layer and made them blue gave them a thick line weight so you would see them plus i broke them so they would not overlap elevation regions Its is really good to have them standout when trouble shooting crazy terrain results

I had a very rough go at it to get you started, its rough around the edges but they will get better with terrain breaks and retaining walls, have a look at the file it should point you in the right direction Draft v0.1terrain.zip
