solver has some good videos on dormers

See if this is what you want its done with auto roof planjune9.plan

I opened your file in x14 rtrt and x13pbr and don't see wall color problem

Post your plan if you can not figure it out

I built your terrain see if you can make use of it , it is my best guess as to what your are trying to achieve Step 30-Plex V1.zip

I had a look at the file Your short cut of not building the terrain correctly is haunting you the negative value in terrain feature does not work build the terrain correctly and your problem should be fixed

To trouble shoot I change the color and line weight of the elevation data so it stands out then look to see if you have overlapping elevation data or even turn all layers off and just show elevation data and study it my guess is you will have elevation data set wrong to cause the problem

You have posted a dwg file they need your .plan file

solid railing type

Watch some training videos on roofs railings and rooms

Have a look at this file it should get you moving in the right direction As-Built.plan

Terrain imported you just need to move it across to your house as you gave me no info as to placement and set the height as described in above post remember to rebuild terrain 21-144 Floor Plan Final Design.zip

The merged cad if you are going to try 13159-BNDRY & topo.dwg

The terrain does not copy it converts to cad, so either you can watch the video and i can share the merged cad, or you can or share your plan file and i can re import the terrain

i had a go it might get what you want , I had to merge the to files then did the terrain import as shown in this video also to raise and lower the terrain to suit building height adjust subfloor height above terrain in terrain specification dialog Import a Surveyor DWG file for a Site Plan or Terrain Perimeter (chiefarchitect.com) Terrain import.plan

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
