I drew a second structure in your plan and had the same problem as you. I copied your walls into a new plan, and the trusses built correctly. Guessing there is an incorrect setting somewhere. Try a new plan. Don't build any framing, just the roof planes. Place a truss.

No. You do need to build/rebuild the roof before drawing the truss. The 12" raise may need to be adjusted, depending on your overhang. You can do the math, or just raise / lower a bit and then rebuild.

Did you rebuild the roof?

I just started my 2015 version of Pro and it has the option. Your 2014 version may have it in a different place. Have you searched Help for Roof Height?

This has nothing to do with rafter tails. Look at the first panel in the Build Roof dialog.

All the webinars focus on Home Designer Pro, or Chief Architect. NKBA is only in Chief Architect. It depends on what type of countertop you want to build. Pro has a Custom Countertop tool, and other tools to make almost any type of counter you could imagine, Suite is limited to using the Soffit tool.

I'm trying to understand, so let me attempt to summarize. Your question is not about how windows are dimensioned in plan, but how you enter the dimension. You would like to enter an inside dimension and have the software add whatever additional you have specified (frame/jamb) etc. Did you know that you can do math within the entry field? You could enter 24+1.5, for example.

Maybe you could comment on these 2?

With Pro, you could define a new thick wall that acts like 2 parallel walls. Your main layer would be 2x4, air gap, 2x4. This is the best way to do this if the wall will have doors or windows. For the ceilings, where you have cathedral ceilings, consider drawing in your own ceiling plane. In the master bedroom, you are looking at the underside of the roof plane, so there is a odd angle above the door.

The defaults you see are what you have. Don't you still need the actual window dimension? Are you saying the program is wrongly dimensioning a window? If I want a 3040 window, I enter those dimensions as 36" high and 48" wide. If I measure an existing window and only get a partial (inaccurate) measurement, then I also need determine how much to add or subtract to produce a valid dimension, which I would then enter into the program.

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.

Raise the Terrain

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.
