AI drafting to your CAD standards

AI Drafting That Follows Your CAD Standards

Every firm has a CAD standards manual, and almost every project drifts from it: layers invented on deadline, notes in three fonts, a dimension style copied in from a consultant file. Nomic drafts to your standard from the first line, then checks its own drawings and the files you hand it against your layer list, styles, and title block before anything is issued.

The problem

Standards drift one deadline at a time

A CAD standard only works if every drawing follows it, and the people who wrote the manual are rarely the ones drafting the night before an issue. A drafter creates WALLS-NEW because A-WALL-FULL was missing from the template, a consultant background brings in its own dimension style called Standard, and one sheet ends up with Arial, RomanS, and a TrueType font nobody else has installed. Each of those plots a little differently, and the set stops looking like one office drew it.

Checking standards by hand is tedious work nobody budgets for. Someone opens each DWG, scans the layer manager for names outside the list, spot-checks text heights, and confirms the plot style table and title block revision are current. On a 60-sheet set that check happens late or not at all, and the drift shows up when a consultant xrefs the file and the layers do not map, or when a sheet plots with the wrong lineweights.

01 / Layers

Layer names your template already uses

Nomic reads your layer standard, whether it follows the US National CAD Standard and the AIA CAD Layer Guidelines or a firm list built over 20 years, and draws every object on the right layer with the color, linetype, and lineweight your template assigns. When the standard has no layer for something, Nomic flags it and asks instead of inventing a name.

  • Discipline designator, major group, and minor group in NCS format
  • Status fields for new, existing, and demolished work where you use them
  • Colors and lineweights mapped to your plot style table
02 / Styles and title blocks

Text, dimensions, and plot styles from your manual

Text goes in with your text styles at the plotted heights your manual sets, commonly 3/32" for notes and 1/8" or larger for titles, scaled for each viewport. Dimensions use your dimension style with your ticks or arrowheads, and sheets plot with your CTB or STB plot style table on the title block your office issues.

  • Text styles and plotted heights per your manual
  • Dimension styles with your ticks, units, and precision
  • Title block attributes filled from the sheet index
03 / Check

Every drawing checked against the standard

Nomic runs the same standards check on its own DWGs and on files your team or consultants send. The check lists every nonstandard layer, style, font, and block, says which sheet each one is on, and proposes a mapping to your standard so the cleanup is one decision per item.

  • Nonstandard layers mapped to the closest standard name
  • Fonts, text heights, and dimension styles flagged by sheet
  • Title block fields checked against the sheet index

Checked against

The code and documents behind every sheet

Name the editions the project is designed to and Nomic checks its own drawing against them before handing it back. Your engineer or architect of record makes the final call and stamps the set.

  • US National CAD Standard, including the AIA CAD Layer Guidelines
  • Uniform Drawing System sheet identification
  • Your firm CAD standards manual and DWS file
  • Owner CAD standards, such as a university or agency manual

How it works

From a sentence to a stamped set

  1. Step 1

    Ask for the drawing

    Say what the sheet needs to show and attach the backgrounds, markups, cutsheets, or photos. A sentence is enough to start.

  2. Step 2

    Nomic drafts it in CAD

    Nomic works in CAD on its own computer, on your layers and blocks, following how your firm drew the same thing before. It saves real DWG files to the project.

  3. Step 3

    Nomic checks its own work

    The drawing is checked against the code editions you name and the source documents. Everything Nomic drew is clouded, and open questions are listed.

  4. Step 4

    Your team reviews and stamps

    Your engineers and architects review the clouded changes, make the final call, and issue the set under their own stamp.

FAQ

Frequently asked questions

Yes. Nomic reads your CAD manual, template, and standards file, then draws with your layer names, text styles, dimension styles, plot styles, and title block. Where your standard has no rule for something, Nomic flags the gap instead of guessing.

Yes. Nomic can draw to the NCS layer format, which incorporates the AIA CAD Layer Guidelines, and to Uniform Drawing System sheet numbering such as A-101 for plans and A-501 for details. Most firms run a modified NCS, so Nomic follows your firm version where the two differ.

Yes. Send the DWGs and Nomic lists every layer, style, font, and block outside your standard, by sheet, with a proposed mapping. That works for consultant backgrounds and older projects as well as new work.

Many owners, including universities, health systems, and government agencies, publish their own CAD standards and require them on deliverables. Give Nomic the owner manual and Nomic drafts and checks to that standard for the project, separate from your firm default.

No. Nomic does not install into AutoCAD. Nomic works in CAD on its own computer, saves DWG files to your project, and returns the standards report alongside them for your CAD manager to review.
