Anytime I've had that happen in my plans it's been when I've dragged the wall around in camera views or the walls are misaligned.

Can you post a copy of the plan for us to look at? I'm not seeing enough information to know how to help. Here's a KB article on how to back up a plan to send to someone else: https://www.chiefarchitect.com/support/article/KB-00987/using-the-backup-entire-plan-layout-tool-to-send-files-to-another-user.html

Only time I see that is when the roofs don't line up at the same elevation. Maybe verify their heights in the dialogs?

Have you tried using the Wall Material region tool? That sounds like it would be a much better solution than manually drawing the tiles. https://www.chiefarchitect.com/support/article/KB-02929/using-material-regions.html

Have you told Chief to build the framing for your walls? I think in Home Designer programs, framing is set to automatically rebuild. In Chief Architect you have to tell Chief to build the framing. You can do that from the Build Framing panel

What path does Preferences show for your Data folder? Edit->Preferences->Folders Panel. The path for My Data Folder will show you where Chief has put it.

Just from looking at the pictures, it looks like you'll need to drag the top of the roof plane over the wall. Chief can't generate an attic wall to fill in the gap between the top of the wall and the bottom of the roof if the roof doesn't extend over the wall.

Spent some time with this plan and it looks like most of the problems are related to your stem wall heights being set differently between the different rooms. For example: the closet room has a Stem wall height of 109 1/2" and the room next to it as a Stem Wall height of 113 1/2". Change this on the Structure panel to match and that will fix some of the problems. Another issue I noticed is the room with the water heater and furnace in it is set to "Room Supplies Floor For Room Above" on the Structure panel for that room - uncheck that checkbox. Once you do that, set the floor height of that room to match the rest of the rooms on the foundation and adjust your stem wall top height. There is a setting set incorrectly in the Basement room type (and probly others). The Floor Structure has been set to be treated like a framing material instead of a concrete slab. To fix this, go to your Default Settings, then Floors & Rooms, then Room Types, Select Basement and click Edit. In the window that comes up, click on the Edit button next to Floor Structure. In this window, uncheck the Framing checkbox and click OK. Click OK out of the Defaults and that should give you back a floor underneath the basement room and the Wet Bar room. Hope that helps!

I don't know that I could work on a 14" screen. If I had it connected to external monitors it'd probly be fine but if I were using it as the primary monitor, it would feel too claustrophobic for me. But, obviously, let your wallet be your guide.

Hi Andy, I just switched to a 2021 16" M1 MBP and it's been great. I was using a 2018 15" MBP before and the performance on X14 since upgrading has been great. The video card in my 2018 was starting to show its age and the upgrade to the M1 mac has alleviated a lot of my slowness problems I was seeing on my older machine. I will say, the 2021 M1 MBP is a bit heavier than my 2018 one but not a ton. It's just enough to be noticeable though. Hope that helps!

Unfortunately I can't tell what's causing your issue based just on the pictures. A copy of the would be really helpful to dig into this further.

If you're wanting to just have your roof cover the existing area, you may want to look at the Minimum Alcove size setting at the bottom of the build roof dialog. I set it to 6' and turned auto rebuild roof back on I came up with something like this:

Without seeing a plan, I can only speculate but you'll probly want to use the polyline driveway tool and use some elevation lines to create the slope. Driveways by default will hug the terrain. If you're needing something where the driveway is rising up from the terrain, I would look into using terrain breaks on the side of the driveway and then some foundation walls to make the supporting retaining walls.
