You need to put in a "complete break" instead of a normal break. What you have now is one stair section with 2 sub-sections and you need two different stair sections. Once you have two stair sections you can make them different widths. Here is some more info: https://chieftalk.chiefarchitect.com/topic/25690-stairs-complete-break-tool/

Did you have the plan open in Chief when you tried to attach it? That can sometimes cause problems. Maybe the plan was too big. You might want to try putting it into a zip file before attaching it. As for your flared walls question, there is no simple way to just make a wall flared at the bottom like that. You might be able to get what you want by adding a molding to the wall that creates the flare. You could also just create the flare using a poly solid. In both cases, you would just set the material to the same as the wall.

The short answer is no, the regular stair won't conform to your terrain. You could probably manually adjust the heights to get what you want. Another thing you could try using is a distribution path with the railroad tie as the object. If it is set to follow terrain, it should look pretty close. I made my railroad ties below just using a soffit.

I would use a cabinet to design the panel. Cabinets in Chief are very powerful and allow a ton of customization. The ability to subdivide a face into whatever components you want and then customize the components can do so many things. You can setup stiles and rails to be whatever sizes you want with custom panels in between.

There is no built in "horizontal filler" tool but there are lots of ways to do things like this including using cabinets, shelves, partitions, soffits, polyline solids, symbols, and others. Might be best to post a picture of what you are trying to accomplish and someone might have better recommendations.

Did you modify your wall type definition? Good chance you made a mistake there. Marking the wall layer as framing or air gap can often cause problems. If not that, then you should post the plan. Also, it's better to give your post a title that describes the problem you're having. Something like "missing drywall in camera views" or whatever. You can always put your name in your signature so it shows up in all your posts.

If it's not a layer problem, then it's probably a video card problem. If you post your plan, someone could tell you for sure.

Best to post questions like this on the Q&A forum. Take a wall cabinet and set the overall size. Then change the door into an opening. Use the split vertical tool to make your dividers. You can then select the "horizontal layout" in the tree and use the "equalize" button to make them all the same size. Lot's of tech articles and videos on cabinet tools if you need more help. Here are a couple of examples: https://www.chiefarchitect.com/support/article/KB-02945/designing-cabinet-fronts.html https://www.chiefarchitect.com/support/article/KB-00433/creating-a-custom-wine-cabinet.html

Turn on print preview. Take a look at your settings in your drawing sheet setup. A line weight of 80 is not going to look very thick when you are zoomed that far out at that scale.

The key to finding the help is to click on the little button with the arrow next to the material class to expand the section.

Well it probably has to do with your ceiling structure but you will get a much better answer if you post your plan. You will probably need to zip it and make sure it is closed when you do this in order to make it small enough to post. You might also want to delete all of the stuff not needed like the furniture.

Not sure what all HD Pro can do compared to Premier. Might want to check out the hometalk forum here: https://hometalk.chiefarchitect.com/ In Premier, you could just create a closed polyline and then set the fill style to your tile pattern. You can also do this for things that already show up in a plan view like counter tops and rooms. You could also create a top down floor overview which would show you all of your materials. Not sure which look you want but you might want to try these.

Sorry for the confusion. When you said "RT" I was thinking GPU raytracing and not CPU raytracing. No grass for you, apparently.

Looks like grass to me. Zoom in on it.

Place a normal doorway. Go to the arch page and set it to "dogear arch". Set the height of the arch. If needed, turn off the casing.
