You have 2 roof planes where you only need one. With manual roofs, it's up to you to fix funky details. Videos on the HD site, the Chief YouTube channel, and my YouTube channel.

Open your stripped down plan. Select a wall tool -- any will work. Hold Shift, and marquee (group) select all the walls. Start a new plan. Paste/Hold Position to put the walls into the new plan. Save the plan and check its size. Also check if the roof is still a problem. If the plan is still too large, try zipping it.

Like most, maybe all applications, you need to identify (select) the text you want to change.

Open Default Settings. Take another look. It's there.

Did you look in default settings?

Like the picture? Yes, those are parapeted gables. The program will do the gable but you will need to do the parapet and other details manually.

This wall seems to be missing from the attached plan. It looks like it is forward of the wall to the right. I assume this is the "front section".

Probably time to learn the manual roof tools.

Select the object and not an edge. How are you moving them?

Review the Materials List.

Make them from a slab, or soffit, or shape from the library, not a wall.

The typical way of creating a gable is via a directive in a wall. Have you tried this? Sounds like video watching might be beneficial. Good getting started ones on YouTube plenty of more focused ones on the HD website.

I've not looked at the plan. Why are you using the Gable/Roof Line tool? I believe the tool is exactly the same in Architectural and Pro.

You can create a new Text Style -- I just used an already defined one to make the text larger. You will also change everything on the roof labels layer.

I'll encourage you to find another plan. Lots of problems just looking as an outsider. If you want a review, you might post on Houzz. https://www.houzz.com/discussions/building-a-home

I know using North/South makes sense, but we have now way of knowing which is North. Use Edit Area (All Floors). Trace one of the roof planes with a Rectangular Polyline. Select the Polyline. Invoke Edit Area -- it will use the polyline as your selection. Use Transform/Replicate to move the selection.

The answer is there. Have you searched Help? The answer is also there.

Search the Home Designer website for insulation. Always a good place to start when you have a question.

Check the library and bonus catalogs. Think about building something up from components -- a cabinet with a valance for the square part, a hood from the library for the top. Google 3D Warehouse for SketchUp symbols that may be imported.
