TeaTime

This is the way. The issue you'll likely start screaming about though is the "auto merge collinear walls" setting that kicks on the second you look at your railings wrong. It's in General Wall Defaults. I generally leave it on but sometimes there's a plan that I really need it to stop "helping".

Nope. But auto fillers only happen to Cabinets, so in your case you can stop the behavior by making it an Architectural Block.

you'll have to draw it manually if you don't want to do a full roof rebuild https://www.chiefarchitect.com/videos/watch/25/drawing-roofs-manually.html?playlist=95

It looks like those walls are set to be solid railing walls? That will happen when doors are placed in railings. If that's the case, try unchecking Railing on those walls, let the room's Ceiling height set the wall heights.

Huh, guess I'd never noticed it did that. It makes sense that the Bay Window is making it's own room, if you Explode the bay that's exactly what you'll have. Weird that Select Similar is able to select it when we can't, though. Seems the Select All option isn't ideal then if there are Bay, Box, or Bow windows present, would need to just do the normal Marquee Select and be careful to avoid those.

For what it's worth, Doug's fix worked because defining it as a specific room type forces Roof Over This Room to be checked. Our fixes were essentially the same. It's worth remembering that Roof Over This Room is not just for auto roof plane generation, it needs to be on for proper roof supporting structural walls to generate.

Are these framed walls on Floor 1 marked as Foundation in order to build footings? If so, uncheck the Foundation setting on those walls. Instead, on the Structure panel check Bearing Wall / Create Wall/Footing Below. If you don't have a Foundation floor, you'll need to build one. These footings will still generate wrong around corners But the wall/footing can be adjusted on Floor 0 independently of the walls on Floor 1.

Been bit by this one before, myself. It seems counter intuitive since you drew your roof planes manually, but you'll want to check Roof Over This Room in that room, otherwise Attic walls won't generate automatically to fill those spaces.

You just need to make a Materials List Polyline that's bigger than the "room" so that it includes the drywall. Try making a Living Area Polyline then converting that to a Materials List Polyline. *Edit: excuse me, "Standard Area Polyline"

Unfortunately those are part of the Marker and as far as I know there's no option to remove the Marker's elevation without removing the whole thing.

It sounds like you're wanting to remove the Markers but keep the dimensions between them. On the General page of the Auto Story Pole Defaults make sure "inner Dimension" is checked. Then under the Locate Elevations section, remove the check mark from the "outer" column, making them all inner dimensions. Then remake your story poles.

Right, sorry - if you set the face item to Door, then down below hit Specify next to Shelves, you can set the shelf count to 1 and swap that with the rev-a-shelf component and set it's rollout distance.

You should be replacing the whole drawer with the rev-a-shelf object. CA has an article on this https://www.chiefarchitect.com/support/article/KB-03142/replacing-a-cabinet-s-standard-shelves-with-rollout-shelves-or-drawers.html though they do it to a Door not a Drawer, it's the same steps though.

Much faster to select a room and just use Marquee Select, Select All.
