AI DWG File Generation

An AI image of a floor plan cannot be xrefed, dimensioned, or issued, and a PDF has to be redrawn before anyone can edit it. Nomic works in CAD on its own computer and saves vector DWG files drawn at full scale in model space, with layers, blocks, and block attributes, so the file goes into your project the way a drafter's file would.

On the sheet

Floor Plan, annotated

An architectural floor plan with walls, doors, room tags, and the column grid every other discipline draws on.

  1. 1Exterior wall with window openings
  2. 2Door, swing, and door tag
  3. 3Room name and number
  4. 4Partition type tag

The problem

A picture of a drawing is a dead end

A drawing is only useful downstream if other people can work on it. The electrical engineer xrefs the reflected ceiling plan, the contractor measures from the plan, and the next revision moves a wall that a dozen dimensions are tied to. A raster image or a flattened PDF supports none of that, so somebody traces it back into CAD line by line, and the tracing is where scale errors and dropped notes creep in.

Files that arrive as DWG are often barely editable either: everything on layer 0, text exploded into line segments, hatches broken into thousands of loose lines, door blocks exploded so a door count means counting by hand. A file like that opens in CAD and still costs a day of cleanup before anyone can put a revision on it.

01 / Geometry

Drawn full size in model space

Nomic draws at 1:1 in real units, so a 3'-0" door measures 3'-0" and a 30'-0" bay measures 30'-0". Walls go on wall layers, dimensions are dimension objects in your dimension style, and notes stay as editable text, so anyone can revise the file with ordinary CAD commands.

  • Model space at 1:1 in feet and inches or millimeters
  • Dimensions, text, and hatches kept as editable objects
  • Paper space layouts and viewports set up for each sheet
02 / Blocks and attributes

Blocks that carry their data

Doors, fixtures, devices, and equipment go in as blocks from your library with their attributes filled: door numbers, fixture tags, circuit numbers, equipment marks. Because the data lives in the attributes, a schedule can be extracted from the DWG, and a fixture count is a query instead of a tally on a print.

  • Attribute values match the schedule Nomic writes in Excel
  • Block names and insertion points from your library
  • Tags tied to the same marks on the schedule sheet
03 / Issue

Ready to xref, revise, and issue

Other disciplines can xref the DWGs Nomic saves, your drafters can revise them, and the set plots for issue without cleanup. Nomic checks each file before saving, including scale, layers, and whether every tag matches the schedule, and clouds everything it drew so review starts there.

  • Consultants attach the files as xrefs and they line up
  • Revisions go into the same file, clouded and tagged with a delta
  • Plotted PDFs and DWGs issued together

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.

  • Your firm CAD standards
  • US National CAD Standard layer conventions
  • Dimensions on the source backgrounds
  • The project schedules and sheet index
  • The code edition you name for the drawing type

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 works in CAD on its own computer and saves DWG files drawn at full scale, with layers, blocks, attributes, dimensions, and text as editable objects. The files open in AutoCAD or any DWG editor.

An image is pixels, so it has no scale, no layers, and nothing to snap to. A DWG from Nomic is vector geometry in real units, with objects on named layers and blocks that carry data, so your team can measure it, xref it, revise it, and issue it.

Yes. The files are ordinary DWGs. Drafters can move walls, re-tag devices, and add sheets with the same commands they use on any project file, and Nomic can take the next revision in the same file.

Yes. Nomic draws at the same origin and units as the architectural backgrounds and uses your layer names, so a consultant can attach the DWG as an xref and the drawing lands where it belongs.

Your team is. The engineer or architect of record reviews the DWGs, makes the final call on the design, and stamps the set. Nomic clouds everything it drew and lists open questions so the review starts in the right place.
