Think about what you want the roof to do. If it is to join at the ridge, the lower pitch roof planes need to change. What needs to change to make them build correctly?

No need to complicate things -- just learn how the program works ... All automatic.

Multiple ways to do this. You control alternate (not default) roof pitch in walls. Roofs build over rooms, so set the ceiling height to set the wall top height to control where the roof starts. I'd make the section with the loft a 2nd floor, but it's not necessary. Manual roofs -- Watch on YouTube: http://youtu.be/LsjUP9ee6jU?hd=1

Because defaults are plan specific. You might want to spend some time with the documentation to get a better understanding of how the program is used.

You need to update your Template plan. Search Tips & Techniques for info.

This trick can be tried any time walls don't connect correctly. Watch on YouTube: http://youtu.be/qZ9maGsukZ8?hd=1

I've not seen the problem you describe. For questions like this, best to attach the plan file.

Open a room, review the Structure panel. You will see where you can adjust floor and ceiling heights. Suggest you create a new plan and experiment a bit to see how the settings work. Use a Cross Section camera to see what's happening.

I've not looked at the plan. You need to make your "attic" a numbered floor. When you build the roof, use Ignore Top Floor, or reduce the ceiling height on the top floor, build the roof, then turn off auto rebuild. Where is this located? Don't understand this, and are directions indicated on the plan? Read about/watch videos about stairs.

Check out the other arch types. There is no match roof pitch setting, but this is easily done by eye or with a bit of math.

I imagine this, centered under a gable. OP wants the sloped parts to match the roof pitch.

Dimensions do not locate moldings, except on cabinets. You can place a CAD line or a Point Marker and dimension to them.

No Yes

Create new floor above.

Who is this "David"?

That's just the way HD works. Draw in your own ceiling plane. Videos on my YouTube channel (link in sig), and I imagine, on the HD website.

That works, visually, but not the correct way to fix the problem. You have used Deck railings for your pony walls. They should be just railings -- no Deck.

Have you checked the bonus catalogs?

Attaching the plan file will help someone troubleshoot.

Draw a section of the pony wall outside away from the building. Make it No Room Definition and just wide enough to fill the opening (no need to be exact). Center it on the opening, then center it on the wall.

Experiment with a ramp.

Pony wall.

What "total SF" are you looking for? The Living Area Label should be shown on each floor. Run a Plan Check if it's not. Each room can show SF as part of the label. See Help for more info.
