TeaTime

That's a different message, specifically stating "the saved plan view", the message in the screenshot is definitely the message you get when the plan/program is trying to close but there's unsaved work. Which is super bizarre. But more specifically: This is the exact behavior you'll see if you have a plan and a bunch of views open and you hit the X to close the program. My first questions are: How are you deleting objects? Are you just pressing the Delete key on your keyboard, or are you pressing the Delete button in the bottom toolbar? Does it do the same thing when you do either? I'm wondering if there's somehow some mixed up system hotkey that's allowing the Delete key to close the program (search me as to how that would even happen though), in which case using the toolbar button you'd not see this happen. Of course, you'd expect to see that same behavior in any other program when you press the Delete key. Very weird, indeed.

A deck is simply a room, just drawn with railings and set as a Deck room type. It's only going to show where its walls(deck railings) were drawn, like any room. Probably the most direct way of literally displaying them on other floors though is to use Reference Display. Probably make a custom Reference layer set just for Deck layers, though this may be a lot of work without a ton of payoff. I feel when I need to show them like this, just outlining it with CAD as you've done is usually sufficient in most cases. And it avoids confusion of someone maybe thinking there's a deck on both floors.

Does there? Two options come to mind immediately with this sort of thing: 1) Exactly what you did: Duplicate floor structure, add air gap. This is great because the cavity doesn't need to show on the plan, and the Relative Ceiling heights are totally functional. 2) Create that room on Floor 3. Shorten the cavity room on Floor 2. The downside is that obviously the cavity room shows on the floor 2 plan and the actual room is separated to Floor 3. Awkward. But it works.

I'm thinkin the Bathroom has the same dropped ceiling, but a lower ceiling height, so it's being pushed into the doorframe. But yeah having a .plan is sure easier to figure out exactly what's happening.

FWIW Most toolbar icons are either an on/off toggle, or they immediately perform some action (making the toolbar change), or they activate a new set of tools (making the toolbar change). There are only two icons I can think of off the top of my head that have some special double click behavior, Make Parallel and Pan. Both of which don't immediately do anything when you click the button since they rely on user input in the view screen, and both have a secret double-click behavior. There may be others but I've not come across them.

Looking at your plan, firstly I was surprised to find how many rooms were not following the default floor height. Just that lavender bit there in the center. All that orange os +16", the red areas though are the problem. It probably would make more sense for all of the left side to be default 0", with the kitchen being -16". It's just easier to manage. But that red area is causing a lot of problems. That whole area has the Floor Supplied by Foundation Below option set, putting their floor heights at -102/-103 this is causing a big issue because the top portion of the Butler's Pantry spans two rooms below it. One of those rooms goes under the Kitchen. That's why there's all these "No Change" values, it has no idea what to say the Ceiling height is for those rooms downstairs because they have multiple values to choose from. Without digging into this whole thing, I'd say start with fixing that area, get the Floor Supplied By Room Below thing under control. If those rooms are supposed to be poured like the garage, then you'll want to make sure the foundation below it makes sense for those rooms.

I'm pretty sure all Lock Toolbars does is remove the little handle on the docked toolbars so they can't be moved around. Though it might also make floating toolbars undockable? But it's not going to lock the location of floating toolbars, or make them "unclosable." hitting the X will always hide that toolbar. To be clear though when you say it disappears are you able to right click the toolbar area and just recheck that toolbar in the Toolbars list? Or is it gone from there too?

Assuming you mean Technique Options -- do you have Denoise When Complete checked? Does checking/unchecking it change anything? What's the Driver Date listed in Video Card Status? Frustratingly NVidia makes those version numbers not align with their actual listed version numbers. (website lists the 11/14/23 Driver as version "546.17 - WHQL" - helpful.) Anyway if it's 11/14, you might actually roll it back to an older version - I've run into issues before after updating to the latest and Support's told me to try the previous one. Some drivers are more stable than others, apparently.

^ That. It'll get unchecked if you've grabbed the wall in 3D and changed the top or bottom. Basically it'll always be that shape because you made it that shape. "Default wall top" allows the program to do what it needs to, ex: auto crop down to the roof shape.

Man I feel like I'm pushing this feature every other day, but honestly the Reference Display is ideal for remodels. as Chrisb222 said, the layers are controlling all this, but if you have an As-Built plan it can be referenced into the remodel plan using an As-Built layer set where all existing/demo items are drawn using whatever line style you want. The benefits of this is that we're not just playing with Layers. You'll find out pretty quickly that if you have existing cabinets and you're just changing the layer/line style of them, then hiding them in 3D Views, you're gonna have a hard time putting other cabinets anywhere near those things 'cause they're still there. Reference them from an As-Built plan, keep your remodel plan clean. Check out https://www.chiefarchitect.com/videos/watch/10266/remodeling-as-built-overlays.html

Marking it as an Attic Wall should be all you need to do. On the Structure panel, Default Wall Top isn't unchecked, is it?

Tip: If you Cut/Paste dimensions they paste back in as Point to Point dimensions. So if you need to keep a dimension but delete something that it's erroneously marking, select it (use Marquee Select Similar if you need to do a group of them, or all dimensions), then use Edit> Cut, Edit> Paste> Paste Hold Position. Then you can delete the offending line/object without affecting the dimension. Just be warned about keeping Point dimensions around, as they run the risk of inaccuracy.

Moldings, 3D Moldings especially, are very often a pain to work with for these very reasons. They show in Plan view as a single line though they're a polyline in elevation. You're not at all alone in the confusion/frustration here. Seems you've already answered the main issue yourself, but there are a few other questions posed here You'd have to open each molding and on the Layer panel you can set it to a new layer, if you have a specific Wainscot layer you can set them to that layer and toggle them on/off as needed. Because it's a CAD Object, it's Layer info is on the Line Style panel. For 3D Moldings its the back edge. FWIW for 2D Molding polylines it can be changed by the Extrude Inside option, you'll see the molding flip around the Line, but for 3D Moldings that changes how it extrudes based on the plane it was drawn in. So if it's drawn in an elevation view, it'll flip inside/outside of the polyline in that elevation, but you'll see no change in Plan.

I usually just work backwards: make a copy of your current layer set, hide the layers of lines you know you need until you're left with a pile of unwanted junk. Select All, Delete. Then copy/paste the stuff I'm left with over to a new plan so I don't have to hunt down unused layers.

It's hard to say for sure without seeing the plan and it's very hard to make out in the image, but it kind of looks like in the cross section that the inner line of the walls is thicker than a single line. You're editing the Siding-6_2 wall, are you sure that those walls are Siding-6_2? Post the plan if you're still stuck.

I absolutely thought the same thing when I first saw the title of the post, o' what a pleasant surprise we all had!

"No" because Grass Regions only work on Terrain, so even converting the Terrain to a symbol breaks the region. But man o man I can't keep myself away from a good challenge. Once again I'm going to push the Reference Display feature. Create a CAD rectangle around the roof. Create another plan, Paste Hold Position so it's in the same relative spot, convert it to a Terrain Perimeter, add Grass Region, then set terrain elevations to the same elevations as the Roof on the other plan, reference it into 3D Views, and voila. Two terrains, two grass regions.

Forgive the snark but this comment is pretty silly - all programs are limited to what its developers have coded. They'd literally have to code all things possible for it to be what you want, which I feel like God has done by giving us the ability to invent pens and paper.

Should just need to break and curve the section of wall where the flare begins. Probably helps to turn off Snaps, they'll probably just get in the way. Lots of eye-balling to match the walls curve to the flare.

Unless this somehow didn't work right in X12, that should do it. Maybe try lifting it 1/16" off the floor - if it's not ON the floor, it shouldn't pick up the floors' moldings. Still requires rebuilding 3D though - moldings don't redraw until that happens.

Oh also, never apologize for newbie questions, that's what this forum is for. Anyone gives you guff over askin something "simple" and I'll pour tea in their shoes.

You can't set the scale in that manner but the very last step of the import process asks you what scale it was drawn in: in, ft, m, mm, etc. Just have to choose the right one. Usually its an easy deduction, like, everything's 12x too big, so choose in instead of ft.

I'd wonder how exactly you imported them. When you right-click one in your User Catalog and hit Open Object, does it open a Material Definition dialog? Or something else, like a picture image or something? I'm guessing they're just not Materials. You might start over by creating new materials right in the User Catalog folder. Right-click it and choose New> Material. I'm pretty sure that's the same back in X13. I think there's also a sort of mass import option under 3D> Materials, too, you might check and see if X13 has it. Should be able to select an entire folder of images and have them batch converted to Materials.

This particular forum is for getting answers to questions about the software, how-to's, etc. You'll want to check out the User Resources section - there's forums for Seeking/Offering services, local user groups, etc.
