Make a copy to play with Right click your linked plan and choose "Replace With" and target your copied plan

OR Make a copy to play with Open layout and goto Tools/Layout/Referenced Plan files and replace the other plan file with your copy plan file in the subsequent dialogue box

OR  
Right click your Layout and choose Make a copy with links to a new folder, and that is a completely contained copy of your layout with its linked plans that are not linked to the originals

this copies your layout with all of its established linked plan files into a new folder within your existing project. This will be a completely separate layout with linked plan files that will have no links to the originals

Turn auto-build terrain on by opening up your terrain perimeter.
Also while selected in plan view,  convert your closed polyline to a road(perimeter) using the convert tool in the edit toolbar.
Recommend turning your terrain perimeter into a rectangle

If you are trying to use it on walls, walls derive their materials from their wall definition. There are other such hard coded definitions that conflict with this as well such as structure(A concrete porch for instance)
I would suggest sharing your plan file with wetransfer or cloud so we can take a look at the window issue

Just FYI mark you no longer have to change the Y origin as that shifts the origin of the symbol, they added an additional function to change the inset. This makes it so that you can insert it into a cabinet OR insert without a cabinet without the Y offset messing up placement for one or the other

If your devices like your keyboard or mouse can create macros then you can have it punch in a sequential shortcut to toggle the library browser then type in some prefix code for your library object. That's the only way you can accomplish it, their is no native hotkey assignability to library objects

these are all just terms of relativity..whats actually happening under the hood is you have a start and an and point and then it is rotating a certain number of degrees. 4 in 12 isnt just a number style, you dont have to have that number style be active in order to utilize it. It is just being translated into degrees, but references a start and end point. so change your start and end point.
Another caveat, with polar checked it will flip if you start drawing in the direction you want. Drawing to sheet left is different than drawing sheet right. So start drawing left and hit tab and then your negative will do what you want

We dont have nearly enough info, sample rate too high. surface count can be super high, number of lights could be super high, number of transparent surfaces, resolution and size of screen, backdrop resolution, texture resolution, materials with pattern from texture enabled etc

select all library items, then apply an "untagged" tag, now select all tagged items and remove the untagged tag, then click on the untagged tag again and those will be the items that need to be tagged

I'm not sure why no one is mentioning this yet but in this industry you really should have a cloud service and give us a link to the download.

use the gable line tool, put some other pitch in there and then change it again to 5. its a glitch

your sill needs to be accurately sized, and you can always set the sill to be air gap material so that it doesnt show in 3d. OR you can create a 3d sill molding and change the z offset so it is sunken...OR make one that represents a cap etc. 
ALSO since this is an interior door, you would need to check the option to separate materials on either side of the door if you wanted a sill on only 1 side

Chief architect looks in 2 places for missing texture files. 
Your Textures Folder
Or in the same folder that the plan file exists in. What DB is suggesting is you make a backup of the plan and include textures so that your coworked can extract the zip file and have all of the textures in the same directory as the plan file
Alternatively you could transfer all of the files in your texture directory into their machines texture directory.
PLEASE NOTE, never a good idea to have your core data files be syncing to a cloud being accessed by multiple machines, so if you do plan on managing resources via the cloud each machine should have a unique short url, robs computer/documents/chief../textures etc.

We can only kind've guess at this because there is no documentation to support it but when flipping the plan the model is re-built and since many electrical symbols options classifications are designated as "mounts to wall" the symbol has to find a wall and there is some sort of internal tolerance being applied that can sometimes be a miss.
If you plan on flipping a plan, you could group select like symbols and designate them as mounts to floor instead of wall before you flip and then they will not be searching for walls but rather they will keep their xy coordinates relative to a model space flip

Try deleting the user library data file with chief closed and then re-open chief and it will rebuild the file

you can trace it with cad lines or you can try converting it to a dxf with an online jpg to dxf converter

Change the text style for Cad,Default
also, I mentioned this to you in email, would highly recommend doing your lot with a polyline and leaving your terrain as a rectangle.
This is a big liability:


 

Custom_Fields is a hash so you would call it similar to other keys in Chief. It is in the Manual:

here is a super quick video, hopefully helps:

snap a cad line just past your high wall and break on that line and drop the remaining sliver down to the lo wall

really Really REALLY REALLY not worth your time or anyone's for that matter. You need an accurate model to get an accurate takeoff. You do NOT need an accurate model to make construction documents. The delta for me is 30% time. That's significantly more expensive than having a lead framer do a takeoff for a few hours. You also need a good handful of custom macros for such things as screws and nails. This is a fruitless endeavor. Just giving you info from a seasoned power user, takeoffs will never be supplanted from a journeyman who knows what they are doing.
