You can do this with auto roof build...BUT...You said that you wanted a higher ceiling (1st floor) and a 2nd floor in the addition???? Also, what are the pitches?

On floor 2: The north horizontal wall of the garage seems to be causing the problem. Move the wall to the south, until it is just beyond the green-dashed lines of the roof overhang.

Build/Floor/Delete foundation Build/Floor/Build Foundation Select 'walls with footings'. NEXT, on floor level 1: Open each and EVERY room (including closets) and designate the room as a 'slab'. Open the structure tab of each room and reset the floor finish (K) to 7/8. This should give you a 4" thick slab floor on top of stem walls with footings, and a finished wood floor (on level 1). P.S. You need to insert a pass-thru window in the wall that is blocking your sight into the fireplace hearth.

So which is it, an awning or a porch roof? They are not the same. Look in your library for an awning. Look in your user guide or the Home Designer Knowledge Base (website) for how to add a roof.

Zooming from exterior to interior (using the mouse scroll wheel) seems to be a new feature of HD2017. As David said, you can do the same thing using the arrow keys (HD 2016 and prior). However, you must use a FULL CAMERA view of the exterior, in order for it to work, as described.

I think this is what KevBel is wanting to do, although it is not feasible (in the real world). Water will flow downhill into the stairwell wall.

OR.. you could just change your ceiling finish (j) in the steam 'room' to 24" or whatever you need for it to be.

Re-post your plan with the new ceiling heights.

LawB10 I agree. I also would like to understand what causes that, because I have encountered it many times.

But...there is a work-around. On level 2, draw a new wall outside the offending east wall. Open this wall and set it to your 'high shed' gable. Extend the north wall over to the new wall, thereby creating a new room (a long narrow room). Open the the new room and check 'use soffit surface for ceiling'. Open the roof dialog and uncheck 'auto rebuild roof'. You can now delete the new wall and move the extended north wall back into place. If any osb is showing in the soffit area, try opening and reclosing the east wall. That usually gets rid of the osb and makes the whole soffit white.

What did you change the finished ceiling height to? It will affect the solution to your roof problem.

Look in your library for cabinet trim. In my library version it is found under: Interiors / Accessories / Kitchen Items / Cabinet Trim

Is this what you are trying to do? Make the 'C' wall invisible. Add one inverted wedge. Size it to match the lower roof pitch and cover up to the ceiling. Then copy/paste and rotate the 2nd wedge. Ctrl/drag the 2nd wedge into the 1st wedge (merge). This makes the interior wall. Ctrl select both wedges (together) and copy/paste. Move these together to the outside of the building and give them the siding material. You also need to expand the stairwell over the 1st floor set of stairs, or you are going to bonk your head.

You have made your attic walls invisible, therefore they are not showing as reaching the roof underside. If a lower cathedral ceiling below the trusses is what you want, you can model a slanted ceiling plane in sketch-up and import it into your model. OR...you can upgrade to HD Architectural and use a sloped soffit to represent that ceiling plane.

As David said, you need to explain things better. I was guessing at what you wanted. As solver said...you have to separate that jutted out area from the powder rm & bathroom with an invisible wall. It's the only way to set the ceiling in those 2 areas lower (2280mm will work). Reset the main powder rm & bath to 2420mm. Also, your right side front wall & the right side back wall of the house are not aligned with each other. When I open your plan, there is no roof showing over the porch. Once again....the right side railing is NOT straight. Reset the roof overhangs to about 550mm.

Is this the look you want? Do what solver said, PLUS---reset the bath ceilings to match the rest of the house. THEN, set both bump-out ceilings slightly lower. Also, notice that the gutter is covering the exterior wall, but the fascia is NOT. Look at the dashed green lines of the roof overhang on the 2D plan. The overhang needs to be bigger, to cover the bump-out wall. The invisible right porch railing wall is not straight.

Begin with your user guide. Look for helpful tips in the knowledge base articles. Set defaults, and draw exterior walls. If the garage is attached, draw the interior wall that separates it from the house, and designate it as the garage. Get the roof structure correct. Build the foundation. Build the terrain. The terrain elevation is set according to the house, NOT the reverse (floor 1 should always be set as '0'). Learn how to manipulate the terrain to expose all or part of the daylight basement that needs to show. These rules and sequences need to be followed, or you will be frustrated somewhere further down the road! Newbies are all too anxious to draw interior walls and start decorating. BIG mistake!

According to the knowledge base article, only Pro allows this feature. Save yourself all the hassle, and just add the microwave to a 2nd base cabinet (toe kick deleted) placed above the oven cabinet.

Open each and every room dbx on floor 1, and put a check in the default box for floor structure(L). Some of the rooms are already checked, and those are the rooms already showing the framing. The next step (of course) is to open the build framing dialog, and put a check in the 'build floor framing' box.

OR... You could draw in an independent room, using the railing wall (make it an 'unspecified' room type), to represent the landing. Set to the right height, this room will automatically show the door swing.

You really should have a landing there. But despite that, there is no option to 'move to the front of group' for doors. It would just be easier to draw in the door swing with cad lines, to represent the door.

Not showing up in the downloaded plan. But I think that if you slightly pull back the edge of the 1st floor roof plane, the problem will go away.

Here's another try at this. Open the room spec box for the entry/hall room. Uncheck 'monolithic slab foundation'. This makes some of the concrete to the left of the step (in the living room) disappear. The concrete showing above the step is appearing because the wall is invisible. Make the wall solid and the concrete is gone. Now is the time to put a doorway there. Next: Open the entry/hall dbx again and look at the floor structure(L). Now open the room dbx for the right front bedroom, and compare the floor structure (L) there. This is why the front door looks to be at a higher elevation than the front room.

Why oh why would you delete your foundation slab? The house has to have a foundation. Rebuild the foundation. Look in the living room and you will see a large slab has appeared. Go back to level 0, and turn on the reference display (so that you can see which part of the slab is showing in the LR). I don't know if this is the correct way to do this, but....select that small slab portion and delete it. Check the living room to see if the concrete is gone. Of course the foundation is going to show outside the front door. What did you expect? Create the terrain perimeter and the put in a porch slab or step in front of the door. Like DCortes said, use a doorway instead of an invisible wall, at the entry to the LR.
