And you can always just go to the 2nd floor and draw in the missing walls.

Most don't know this exists.

Attach the plan and I'll take a quick look.

Just to be sure, drag the roof edge well past the wall manually.

You need a stairwell. You can draw 4 walls (usually railings) on the 2nd floor above the stair forming a room, then make the room type Open Below, or select the stairs and click the auto stairwell icon in the edit toolbar. There are some good hour long getting started webinars on the YouTube channel linked above, and the Home Designer website has the Knowledge Base and videos too.

See them from where? Can you post a screen capture that shows where the stairs are missing? What is the problem doing the windows?

Don't understand what you are asking. What do you mean by "incorporate"? Your picture seems to show windows, not a glass wall.

Search the forum and https://www.homedesignersoftware.com/ for parapet.

X11 and X10 refer to Chief Architect, not Home Designer (this forum). In any case, if there is a problem, you should send something directly to Chief as they don't seem to monitor this forum.

What's the problem? Your image shows the front of the house, not the roof, so it's difficult for someone to know what it's supposed to look like.

Suggestions in order of best to worst. Look at using a Pony Wall with the different material on the top or bottom section (not sure which will work). A Wall Covering might also work. A Custom Backsplash (or soffit, or slab) could also work. A slab you can draw in plan, making it thin and wrapping around the building. -- Have you figured out the parapet? Start a new thread on it if help is needed.

Are you kidding? Via the help menu, or the ? icon, or F1

A link on the desktop is pretty quick and does not seem clunky to me The Qt stuff is the built in help system -- essentially the reference manual in a different format.

I was thinking something like this.

What problem are you having?

That's not normally shown on an electrical plan, but you may be able to use the CAD tools to do it.

Any reason to not use multiple cabinets?

Review defining/changing a wall type. Build>Wall>Define Wall Types ...

@Donco15 What are you raving about -- the blue and yellow walls? That's the way all Chief Architect/Home Designer products looked using the defaults prior to the 2019 versions. For some reason, they changed to gray wall fills for the recent versions.

Pro has plan files and layout files, and both use templates. Are you asking about a layout template? (some refer to a plan as a layout, but in Pro they mean different things) I'm not understanding "download-able sets for framing, hvac, room elevations, etc.". Taking framing as an example, what would you expect to find in a template? How would you make use of a framing template?

What are you wanting? People mostly create a new, or change the default template to be what they want.

One other suggestion. Add your 2nd floor rooms now. When working on the roof it's important to have the structure below in place.

Manual roofs just take practice. Good videos on the Chief Architect YouTube channel. David Potter YouTube also. These are 12, others except the back porch are 7. Goal was to align the ridges when looking from the front, and make the gables in the front match.

Your plan, specifically the angled garage makes a clean roof difficult. I'm not a fan of a hip roof with a few gables added for "looks", so here is an idea for a all gable roof. Done manually starting with an auto build, quickly and needs work. You might start with something like this, then add the hips back in.
