CAD standards
Your company layer standard comes in through an Excel template downloaded from the Manager Portal, and covers only the layers SheetAgent generates rather than your whole standard. Import it once per firm and every drawing built afterwards uses it. An older drawing with its own layers keeps them until you choose to standardize.
What CAD standards means here
CAD standards in SheetAgent for Civil 3D means the layers, linetypes and colours it uses for the things it draws. It is a narrower idea than your firm's full CAD standard, and deliberately so.
What the template asks for is the parts SheetAgent generates: viewport layer names, match line layer names, linetypes, colours, and the key map hatch. Nothing else. Your own layers, and everything you draw yourself, are untouched by it.
That is why filling it in takes minutes rather than being a project. You are not describing your standard to the software; you are telling it which of your layer names to use for the handful of things it creates on your behalf.
Loaded standards apply to every drawing built afterwards. A drawing that already has its own layers keeps writing to them until you choose to standardize it, so you never end up with old and new pairs of the same layer.
Importing your company standards
The standards come in through an Excel template you download from the Manager Portal. Access to it there is deliberately limited, so one person holds the company standard rather than several people each producing their own version of it. On a solo or small team, that person is you.
Step 1. Download the template from the Manager Portal.
Step 2. Fill it in. It asks only for the parts SheetAgent for Civil 3D will generate, not your whole company standard: viewport layer names, match line layer names, line types, colours, and the key map hatch. That is usually under five minutes of work.
The workbook only lets you edit the cells that are yours to set, and anything it cannot read falls back to the built-in defaults, so a stray edit will not stop the import.
Step 3. On the Welcome tab, in the Company Standards section, press Import Standards and select the file.
The Company Standards label on the palette changes from a circle to a tick once they are loaded.
This is a one-time job. You import again only if the company standard itself changes.
On a drawing that already has its own layers, importing does not rename anything on its own. See Standardizing an older drawing.
Standardizing an older drawing
A Health tile reading that layers and standard variables are loaded, and inviting you to standardize, is expected rather than an error. It appears on an older drawing whose layers differ from the company standards you have loaded.
Step 1. Open Health and press Standardize.
Step 2. Review the changes in the dialog and choose which variables to apply, such as layer renames and the match line and key map hatch variables.
New drawings need no action. A drawing with no existing layers adopts the standards quietly when it opens, so the tile never appears.
Until you standardize, the drawing keeps writing to its existing layer names on purpose, so you do not end up with old and new pairs of the same layer.
Standardizing is a per-drawing choice. Applying it in one drawing never changes another.
