In an elevation, check Display Options. Is the objects layer set to display? Each camera type has its own layer settings.

Probably because all the lights are pointing down, making the ceiling one big shadow.

Not sure what you are describing, but you can reflect an object, or Architectural Block about itself.

This?

Soffit with Fir material.

That's called the Living Area Label. Running a Plan Check will usually get it back. If not a forum search should bring up more info.

You don't need to draw trusses, or even tell the program you are using trusses. You probably do not need to build any framing. Set the roof structure to give you the look you are after.

Custom Backsplash, Soffits, Slabs, Shapes (from the Library) ... Thank about how you can use the existing tools to do things like this.

I'd focus on the overall design first, then worry about things like missing bits of wall.

Auto built gable attic walls are by default marked No Room Definition. To create a room, make sure all the walls forming the room do not have this setting checked. For the best responses, it's helpful to have the plan file to review. Close Pro, Zip if needed (14 MB size limit) and attach. I'll also suggest you reconsider the design to eliminate this condition.

Pro 2022 is comparable to X13, and none of the Chief Architect/Home Designer products are able to open newer version plans.

Your architect should understand the problem. Not really. Give him a PDF of the plan and he can quickly redraw.

With Pro you could create a single cabinet like this, but for a filler, a blank fronted cabinet is the way to go.

A forum search will often find answers.

You will need to use parts, partitions or other items to assemble a cabinet.

Not with a single cabinet.

A Ceiling Plane might work, or a Custom Backsplash.

Just like it is built.

Set this to 0.

Open the cap, set its height, center it over the chimney.

Then you created a room that you can control the height of. Walls will build up to a roof automatically -- that's why you have attic walls. The simplest way is to use a solid like a slab and make it as tall as needed.

Place a thin soffit, change its material.

Please post images directly -- no need to make a PDF of an image. This makes it easier for others as an image shows in the forum.

Maybe, but I would use solids, like a soffit to represent the footing. Everything is easier as you have more tools to work with, especially with Pro.
