Make upper flight of stairs 5' wide.

Add detail above round window in front.

Ideas on the floor plan. The Laundry seems very big -- anything else that could go in there?

The hall past the master closets looks small, like it might be a bit congested. 

Are you working from field measurements, or just guessing at pitch and other dimensions? If guessing, I'd suggest a site visit to gather all the necessary measurements.

You have 3 different pitches, over the large space, over the connector between kitchen, and over the master. These need to be correct in the model for the roof to build correctly.

The fascia height is dependent on several things -- roof pitch, overhang and ceiling height.

The simple solution is to raise the master bedroom/bath area ceilings to force the fascia to align. 

Not sure which wall you are referring to, or what looks wrong.

I changed the pitch on the 2nd floor roof to be the same. Not really suggesting this, but I was curious about how it would look.

I should have been more clear. On a 1-1/2 story house, the LAST step is raising the 2nd floor ceiling heights.

You will want to get the roof to auto build correctly first, then raise the ceilings.

The master bath and hall bath have different ceiling heights than the master bedroom and hall. 3/8" different, but that's enough to change the roof.

David seems to be correct. You can create a representation, but it won't be very accurate.

Start by getting your room heights correct.

Adjust roof pitch as needed. The roof between the bedroom and kitchen is a lower pitch, for example. You can break a wall (with the wall break tool) then assign a new pitch to just a portion of a wall. Make sure the fascia height matches the structure.

Thinking of just the roof, You will need to think about the connector space leading to the garage. I show a roof over the hall and closet which works OK. Anything bigger does not easily work with the existing roof.

Did this one this morning.

And this one for a thread on ChiefTalk sometime last year.

Combine the 2 with a bit more work and you should be able to do what you need.

I'd create a small room with a floor raised to the bottom of the columns. You might choose Balcony as the room type.

The 3 outside walls would be a Pony Wall with the bottom part (where the columns are) as a room divider.

Fill in below the columns with a soffit.

The arch is created with a Pass-Through, placed in a camera view.

Just did this one as a demo.

Check again on your walls.

As for your question, set the 2 end walls to Full Gable.

The automatic bay tools are rather limiting. Suggest you draw your own.

Are you able to change other parts of the roof to metal?

How do I center the stem wall on the footer? I know in Premier there is an option under the Foundations tab. I can't seem to find a way in Pro

I don't think you can. Pro tends to produce "representative" instead of "actual". I note that on the plans with a link to a detail I have created manually.

It's like trusses. I draw in trusses, but they are not supposed to represent the actual truss. Rather to act as a visual cue to say trusses will be used.

Have you seen Creating a Cross Section Detail in Home Designer Pro

I don't think you can automatically do what you want. You can place the slab at the top of the stem wall.

Is the detail shown above taken direct from a plan, or is it a purpose drawn detail?

If you are drafting and producing construction documents for a living, I recommend you consider Chief Premier.

Pro is a good tool, but it's quite limited in some areas. Premier gives you the tools and flexibility do do most anything, with, as David would say, a good bit of study.

No new layers.

Is there a real need to show outlet wiring?

I would only show switched outlets.

Set your floor structure to 0 (zero).

The space (rooms) above are likely set to a slab. Change the floor structure to something more appropriate.

You should then have drywall on the ceiling.

You may also need to make the basement walls higher to compensate for the increased thickness of the floor structure above. 

There is a button on the Edit Toolbar to reverse a wall. The software often does this.

Garage floors are normally lower than the house floor for safety. You can change it in the Room Specification dialog.

.

Not David, but I believe covering the value with a different one is the only way. The program is designed to show dimensions the model produces.

Define "slant".

You can also set the wall above as No Room Def instead of deleting it, then change it back.

See image.

I see no garage.

I just tried it as I rarely do foundations. By setting all space except the area over the basement as a slab, and specifying the correct height for your basement walls in the Build Foundation dialog, you should get what you are after. 

Will the house be on a slab, except for that one area?
