Post the plan with a saved camera and I'll have a look.

When you select a wall in plan, or in a Dollhouse view, the edit handles are on the exterior side. I'm not sure about a wall selected in a Full or Floor camera that have no identifying features such as a door. You can easily reverse the wall if you guess wrong.

I could, but then you would not learn. Anyway, I don't usually save others files unless I make major changes. If you will be designing these for your husband to build, what I showed in the video should become automatic.

Yes, I've had similar problems.

Don't understand your question.

General panel of the wall dialog.

A second floor is not necessary. What are you having a problem doing?

I normally turn off the automatic cabinet (upper and lower) backsplash and use a Custom Backsplash. This gives complete control. You can also use a Custom Backsplash to patch in the part you need.

Have you tried setting the pitch in the garage door wall? Look in the Roof panel.

What does it look like with a standard render?

Could you post a screen capture? This is from Suite 2016.

Change the materials, tread thickness, overhang etc to create concrete steps.

I don't know of such. Hovering your pointer over the icon will show its name. You can find everything and more under the menus too.

Use 2 cabinets.

I'd contact support providing images of the pointer in HD and some other application.

You did not say where -- upper base etc. You have the Partition tool which may be used for a simple flat filler. For base cabinets, make a cabinet that is 3" wide, and remove the drawer and door. You can save this cabinet to your library for reuse.

I might draw in the unit next to yours making it the correct depth front to back but just 12" or so wide. Then your roof will build against the wall automatically. You could delete the walls after your place is complete if desired.

A bit on aligning walls. You can click YouTube at the lower right after the video starts to watch full size on YouTube. I forgot to show in the video that the center room has a different (not the default) ceiling height. It's 109", and everywhere else is the default of 109.125". This 1/8" changes how the roof builds. My guess is that working one-on-one with someone would be better for you.

Have you reviewed these resources? The 1 hour webinar recordings on YouTube helped me get going when I started. The basics are the easy part, it's when something is just slightly different and the software falters, especially with anything except Pro, the that real work starts.

These are some of the wall alignment issues. Grab the back wall of the master bedroom and drag it across to the back wall on the other side of the house. You will see they don't align, and I imagine they should. Consider furniture placement too. In the bedrooms, the beds will need to go against the bathroom walls -- not the best place, and where will other furniture go? Imagine yourself using the toilet in the master with the door closed. There is not enough room to stand up without opening the door. Not trying to bash your work, just suggesting that you work through everything as you go.

Another something to consider is how the roof will be built. Your interior ceilings should reflect the bottom of the roof framing. Scissor trusses are common for a vaulted ceiling, so the ceiling plane would have a different pitch than the roof.

What didn't work? Here I draw in a ceiling plane, copy and reflect it about the center, then join it at the ridge.

I took a quick look at your plan, and want to suggest you are getting ahead of yourself worrying about the roof and ceilings when there is so much that needs to be corrected first. I'm referring to walls that are not aligned, and dimensions that should be changed. Strive for 1/2" as the smallest fraction, and whole numbers are preferred. Your master closet, with hanging on 3 sides will only give you about a 10" isle, and there are other things. Not knowing anything about you, the house, or your building site, I'd be thinking about something like this. By changing the orientation of the center of the house, you get far more light, and far better views out the back

You need to draw in your own ceiling planes. They work just like roof planes.
