Best AI for Text to CAD in 2026
Last reviewed: November 2026

Text to CAD means two different jobs depending on who is typing. A product engineer asks for a 600 mm manhole cover with lifting slots and wants an editable solid model to send to manufacturing. An electrical engineer asks for receptacles on E-201 laid out to the furniture plan and circuited to panel RP-2, and wants a DWG sheet in the firm’s standards. The first is mechanical CAD: parts, features, tolerances. The second is building drawing production: plans, layers, blocks, tags, title blocks, and code.

Rankings

5 tools ranked for text to cad

01Our pick

Nomic

Turns a sentence and the attached backgrounds into DWG plans, layouts, details, and schedules for buildings

Best for: Architects and engineers who want to describe a building drawing in plain language and get a DWG in their firm’s standards

  • You describe the drawing in a sentence and attach backgrounds, furniture plans, cutsheets, or markups; Nomic lays out the design and circuits or dimensions it
  • Saves real DWG files to the project on your layers, blocks, line types, text styles, and title blocks
  • Covers architecture, structure, MEP, and fire protection, from power and lighting layouts to sprinkler layouts and details in house style
  • Checks its drawing against the code edition you name, such as the NEC or NFPA 13, and the source documents, and clouds everything it drew
  • Connects to Autodesk Forma, Bentley ProjectWise, Trimble ProjectSight, SharePoint, Egnyte, Fieldwire, Google Drive, Box, Dropbox, Microsoft Teams, Outlook, and Gmail; SOC 2 Type II

Pricing: Free; Individual $20/mo; Business $40/user/mo with a 25 seat minimum; Enterprise custom

02

Zoo Design Studio with Zookeeper

An AI-native mechanical CAD app whose conversational agent, Zookeeper, builds editable 3D parts from prompts

Best for: Product and mechanical engineers who want text to CAD for parts with a free way to try it

  • Zookeeper builds editable 3D models from a prompt or iterates on an existing design
  • Models are written as KCL code, so the agent’s work can be read and corrected
  • Point-and-click modeling in Design Studio is unlimited on every plan
  • Runs in a browser or on Mac, Windows, and Linux, with an API and MCP server

Pricing: Free with 20 agent minutes/month; Plus $20/month; Pro $99/month; Team $399/user/month

03

Adam

An AI CAD copilot that works inside Onshape and Autodesk Fusion, plus the open-source CADAM text to CAD tool

Best for: Hardware teams that want to generate and edit parts from prompts without leaving Onshape or Fusion

  • Edits parts with prompts using selected geometry as context, inside Onshape and Fusion
  • Turns rough CAD into parametric models
  • CADAM offers open-source text to CAD for quick parts
  • Free plan, with a seven day trial of Pro

Pricing: Free; Pro $40/month; Max $200/month; Team plans per seat

04

Hypar

Cloud space planning with AI layout suggestions and an AI chat that edits the model, exporting to Revit and DWG

Profile

Best for: Architects and planners testing program layouts for healthcare and workplace projects before Revit

  • Imports DWG, PDF, and laser scan underlays plus an Excel or dRofus program
  • AI layout suggestions and a chat that can edit the model on paid plans
  • Exports to Revit, Rhino, and Excel, with DWG and DXF export on paid plans
  • Free Personal plan for evaluation

Pricing: Personal free; Professional $100/user/month or $1,000/user/year; Studio custom

05

ChatGPT, Claude, and other general-purpose AI

Writes OpenSCAD, CadQuery, or AutoLISP code from a prompt; output quality depends on your checking

Best for: Engineers comfortable reading code who want a quick script for a simple part or a repetitive drawing task

  • Generates parametric scripts that open in free tools
  • Explains CAD concepts and API calls
  • Low cost to try

Pricing: From about $20/user/month on individual plans

Frequently asked questions

Answers to common questions about this comparison.

For mechanical parts, Zoo Design Studio with Zookeeper and Adam are the leading options, and both produce editable 3D models. For building drawings such as power plans, sprinkler layouts, and enlarged plans, Nomic produces DWG files in your firm’s standards. Hypar covers AI-assisted space planning that exports to Revit.

Yes for building drawings. Nomic takes a sentence plus attached backgrounds and saves a DWG laid out, dimensioned or circuited, and drawn on your layers and title blocks. Most text to CAD tools for parts export STEP or similar solid formats rather than DWG drawing sheets.

Not as a released feature as of November 2026. Autodesk has shown neural CAD and the Project Bernini research prototype, which Autodesk describes as not commercially available, while shipped Fusion AI features include AutoConstrain. Adam offers prompt-based editing inside Fusion through an add-in.

No tool removes the review step. Mechanical parts still need an engineer to check fit, tolerances, and manufacturability. Building drawings still need review against code and design intent, and the engineer or architect of record makes the final call and stamps the set.
