I don't believe you can automatically do what you want. Tell us what is wrong with how the program is working now. For windows and doors, it seems like rough opening is the important measurement.

Select them as you would select any other item by clicking on them. Do it from a camera view or in plan. One at a time, or both. Right click will bring up the context menu.

Chief Premier, but not in the Home Designer titles.

Your roof is being built over the 1st floor, so a Dollhouse view of the 2nd floor will show the roof. While on the first floor, select both roof planes, right click and "Display on Floor Above".

If you are in fact using Chief Architect Premier, or Interiors, and not one of the Home Designer titles, then the correct forum is ChiefTalk. https://chieftalk.chiefarchitect.com/

Don't use a Break, do the roof manually, or use the Gable/Roof Line tool.

I'm going to give a David Potter response. Read up on Terrain in the documentation. Watch Terrain videos etc.

Sounds like it. This should stay checked, unless you do something that causes the program to turn it off, and then, the program will ask. Forgot to say also, check for wall marked Foundation Wall. None of your walls need this. You can easily select all walls and uncheck for all. Click the Wall tool, then while holding shift, marquee around the plan. Do you have the Lintel panel in Wall and Door dialogs? You might be able to use it instead of manually placing something over each to simulate a beam.

I often do this outside the plan, then once the assembly is correct, group select and Point to Point move into position. 1) Draw a CAD box (square) and size it 48x48. Notice I don't drag, I enter dimensions. This is a placeholder for your stair landing. 2) Draw in two stair sections. Open each and size them as needed. I normally have the program build stairs and do a Make Best Fit to get the settings. 3) Select each section and using the Point to Point tool, move the corner of each section to the corner of the CAD box (landing). 4) Click the Stair tool -- it does not need to be the Landing tool, and click between the sections to create the landing. 5) Delete the CAD box as it's no longer needed. http://screencast-o-matic.com/watch/cbehrD6uXi

I'll do a video. Check back in an hour.

The only limitation is the inability to save. You might check that your system meets the minimum requirements.

It gives you a total length, not a count. Total Length / Your Stud Length = Number Needed

You would typically have a post with a footing, not a wall with a footing. Consider using a Room Divider to define the porch area, and the Post With Footing tool for your posts. I use a custom Room Divider. 1 (main) layer with the material set to Opening No Material, and a thickness of 1/512. The program will display the thickness as 0, which is OK. Use a Slab, or one of the terrain features to give you something to paint your pavers on for the 3D views. Also, turn on Auto Rebuild Foundation. You will see some additional problems. That's the way the program works. And How I might do the porch roof.

I'm familiar with their product, although I have never used them. The disadvantage, and why I would not choose them for a project of mine, is the problem of thermal bridging. They are essentially a prebuilt wall with high quality cavity insulation. I'd want an additional layer of foam on the outside, and they still need sheathing. I'd want to look closely at the total cost of their package, vs a conventional SIP and standard, well insulated construction. How about a slab?

The first floor, floor structure does not matter much, unless you have a basement, and even then, the basement floor just moves up or down a bit. The program references from the first floor, floor (subfloor or finished floor). The second floor, floor structure is more important, mostly because of the stairs, which will obviously change. You will also need an idea of how the roof will be built, how much insulation etc.

You might try uninstalling then installing the program.

What happened when you Install Core Content Update Library

You need to be more specific. What "Plumbing Fixture Catalog" are you looking for? Have you looked Here?

After correctly setting floor 1 defaults, you could also use Edit>Reset to Defaults. This will apply the default settings throughout.

Is it a Bonus Catalog? One you downloaded from the website manually?

I just noticed that too. Here is a different take on your front.

Is the upper floor supposed to extend over the lower? If so, an automatic return will not work, and you will need to draw it manually.
