Text to CAD for Building Drawings

Text to CAD usually means 3D solids for product parts: a bracket, an enclosure, a gear. A building drawing needs different inputs, because a power plan or wall section only makes sense on the architect's background, in your layers, at a plotted scale. Nomic takes your sentence together with the backgrounds and your CAD standards and saves a 2D DWG your team can review and issue.

You send

  • A sentence or two describing the drawing
  • Architectural backgrounds as DWG or PDF
  • Furniture plans, cutsheets, or markups the drawing depends on
  • Your CAD standards and a past project to match
  • The code edition for the project

Nomic hands back

  • 2D DWG files drawn on your backgrounds and standards
  • Layouts with title blocks, ready to plot
  • A list of the assumptions Nomic made
  • Plotted PDFs with revision clouds on Nomic's work

On the sheet

3D Building Model, annotated

A building model where each element carries its level, system, and size, so sheets and schedules read from it.

  1. 1Floor slabs with level datums
  2. 2Columns on the structural grid
  3. 3Selected level and its properties
  4. 4Modeled element with its system data

The problem

A prompt needs a building to draw on

Ask a general text-to-CAD tool for a restroom plan and you get geometry with no context: walls that ignore the architect's grid, a toilet compartment drawn to an arbitrary size, nothing on a layer your office uses. Building drawings are always drawn relative to something, including the current architectural background, the structural grid, the ceiling heights, and the way the firm shows each system.

The request a design firm actually writes reads like this: "Lay out receptacles on Level 3 per the furniture plan, circuit to LP-3A, our standard." A drafter knows to pull the right background, check the furniture plan revision, and draw on the power layer. A one-line request only works when the drafting system brings that same context with it.

01 / Request

Write the request the way you would to a drafter

Nomic reads a plain request plus whatever you attach: the architectural DWG, a furniture plan PDF, a cutsheet, a markup. Short requests work because Nomic fills the gaps from the backgrounds, your standards, and how your firm drew the same sheet on past projects, then lists every assumption it made.

  • "Draft the Level 2 RCP from the arch background, 2x4 lay-in grid"
  • "Typical slab edge detail at the loading dock, in our style"
  • "Plumbing plan for the Unit B bath, mirrored for Unit B1"
02 / Draft

A 2D DWG on your backgrounds

Nomic works in CAD on its own computer, attaches the background, draws the sheet in model space with your blocks, and sets up the layout and title block. The result is a 2D construction drawing at the scale you issue, which is what the plans examiner and the contractor work from.

  • Plans, ceiling plans, details, and schedules
  • Drawn at 1:1 and set up at 1/8" or 1/4" scale on the sheet
  • Tags, notes, and title block filled in
03 / Check

Checked against the request and the code

Nomic checks the DWG against what you asked for, the attached documents, and the code edition you name, then clouds everything it drew. Assumptions Nomic had to make, such as a circuit count or a mounting height, come back as open questions for your reviewer.

  • Each item in the request confirmed on the drawing
  • Code checks for the drawing type
  • Assumptions listed for the engineer or architect

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.

  • The request and attached documents
  • The architectural backgrounds
  • NEC, IBC, IPC, or IMC for the drawing type
  • Your firm CAD standards

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

Text to CAD means describing a drawing in words and getting a CAD file back. For building projects, Nomic takes the description together with your backgrounds and CAD standards and saves a 2D DWG drawn on the project, ready for review.

Text-to-3D tools for product design generate solid models of parts for manufacturing. Nomic drafts 2D construction drawings for buildings: plans, ceiling plans, details, and schedules on the architectural background, in your layers, set up on sheets for issue.

No. A request like "power plan for Level 3 from the furniture plan, circuit to LP-3A" is usually enough when the backgrounds and standards are attached. Nomic lists anything it had to assume so you can correct it in the next prompt.

Nomic saves DWG files and does not edit Revit models. For teams that model in Revit, Nomic produces DWGs and change lists that a modeler links into the model.

Nomic checks its own drawing against the request, the backgrounds, and the code edition you name, and clouds what it drew. Your engineer or architect of record reviews the sheet and makes the final call before anything is stamped or issued.
