No. For your flat roofs, look for Shapes, then Closed in the library. They are on the Geometric Shapes layer (or something like that).

What did you try? You can go into the toolbar folder and delete the toolbars there. HD will rebuild them from a copy on the next run.

Try Preferences -> Reset Options -> Reset Toolbars This will reset to defaults so you may loose any changes you have made. Right click on a toolbar, then Toolbars Is the missing toolbar checked to display?

And this is why I always try to suggest people start a new thread and reference the older one. People rarely look at what's above when someone adds on to an existing thread. Thanks for the update.

How about uploading a plan, or a couple of images showing how this fixes the problem.

What you see is the way the program works. Normally you draw with Angle Snaps on -- at least that's how the people that developed the program think. When you turn Angle Snaps off, the cursor changes to remind you. I always leave Angle Snaps on, and never have a problem. Search Help for "pointer icons" (with the quotes) for more info.

How do you spline them? You can Change Line to Arc on the straight ones, but that's not splines -- or maybe it is?

I've never understood the Spline Sidewalk in Home Designer. In Chief when you create a Spline Sidewalk, you can select Advanced Splines and get additional control much like you are wanting, but this does not seem to be the case in Pro. I'd contact support and ask. The documentation is really poor in describing this feature.

Does this happen with all plans, or at least other plans?

There is an awning over awning. I was thinking about Opening Indicators, but it seems Architectural does not have these.

Open your window, review the available types and settings. You don't have the option for a fixed over operable unit.

The title bars in layout are just CAD lines. Turn on the Drawing Sheet (not necessary, just serves to help with positioning), draw what you need, import your PDF or images, print.

The Home Designer website is full of articles and videos. Starting your search there will find content from the website and forum. Suggest searching for bow window.

Suggest reading the docs and experimenting. Here is a link to some discussion on ChiefTalk https://chieftalk.chiefarchitect.com/search/?&q=global symbol mapping&page=1&search_and_or=and&sortby=relevancy

Global Symbol Mapping is poorly explained and poorly understood. In any case, you need to create a new material set at the proper angle for each angle.

Tools menu. Display Options If something does not display as you expect, check Display Options in the view where it's missing.

Is the terrain set to display (Display Options) in your 3D view?

Someone will need the plan file to investigate further, but it sounds like you have tried what I would try. Do you have another PDF print driver loaded? Bullzip and CutePDF are two that are often recommended. I'd try printing using one of them as a test.

It looks like Line Weights were on when you sent to layout.

Taking another look at the rendering and noticed this. You may be able to do this is Architectural. In Pro it's simple using the manual roof tools.
