I did not say that. You can do quite a bit with Suite, if you understand the program and how to work with its limitations. I cannot imagine designing a house with innovative wall layers, interfaces, and advanced framing using Suite or Architectural. Pro is very capable and probably all you would need to do construction documents. Chief Premier has many additional features that make the work easier/faster etc, but the core is essentially what you have with Pro. One thing you might consider is buying Premier, then selling it at the end of the project.

Architectural and Suite have about the same roof tools. Pro would make it simple. You could rent Pro for a month to finish the design and do your construction documents.

Can you explain "remove them". Do you want to delete them?

What $60 a month are you referring to? Your question might be best addressed to Chief directly. Many catalogs can be downloaded free of charge, some are available for optional purchase, and some are only available to Chief Architect Premier users with active Support and Software Assurance (SSA).

Could you point us to that phrase in the documentation?

Why not use a framing member like I show?

A picture of what you want, or a verbal description always helps. I'll make a guess. What would happen if you select a framing member, lets say a 2x4 from a wall, open it and change it into a 4x2. Does that make sense?

What happens when you try?

I did not look at your plan, but search my YouTube channel for backsplash for an idea for the braces.

Open a wall and review the structure panel. Settings are there. Check Help for specifics.

Something like this?

You can do things like this easily with Architectural and Pro.

You would get better help if we could see what you are trying to model. A head on picture taken from the street does not provide enough detail. You must do this with walls and use a doorway or window etc to create the arch. You don't need to use only walls. You can use soffits too. Walls and soffits can share the same space, or soffits can be positioned on the wall to give you something to place a molding on. Try to think of the tools you have available and what they are capable of, then use them as needed to build the model. With Suite, you have limited options, so you need to make up for the shortcomings of the software.

Try setting the floor and ceiling defaults in the terrain plan, then copy the house to it using Edit Area.

Read in Help about Reference Display.

Could you show a screen capture so we see what you see?

I opened the plan you attached in Pro 2021 and was able to make all sorts of changes.

And just a FYI. The plan did not need to be updated to X12, it just needed to be opened and that Allow For Editing flag set. Any version from X6 on could have done it.

How do you know it was checked? I've never seen this not work. Could you attach the plan file and I'll take a look.

Select the terrain and click this (look in the Edit Toolbar). Reshape the hole created if/as needed.

I did this in 2 minutes. Try working each problem by itself, and do so in a new, simple plan. Once you are successful, start working in the real plan.

Except for the roof, that looks like standard construction -- walls with windows. For the roof, change the structure to be thin like the glass and materials to Opening No Material and glass.Use roof framing for the battens. Build the roof thicker, build framing, then build the roof thinner so the framing protrudes.
