One photograph, three outputs: a dimensioned drawing, CAD geometry, and a 3D model.
## Install Pick one. Each method sets the skills up for your agent. ### `npx skills` (recommended, cross-agent) ```bash npx skills add MeltFlexDevs/techdrawai-skills ``` ### GitHub CLI (v2.90+) ```bash gh skill install MeltFlexDevs/techdrawai-skills ``` ### Claude Code marketplace Inside Claude Code: ``` /plugin marketplace add MeltFlexDevs/techdrawai-skills /plugin install techdrawai@techdrawai ``` ### MCP server only If you want the tools without the skills, add the MCP server directly: ```bash claude mcp add techdrawai -- npx -y techdrawai-mcp ``` Configuration for Cursor, Claude Desktop, Codex, VS Code and Windsurf is on the [MCP page](https://techdrawai.com/mcp). ### Setup script Universal fallback: ```bash git clone --depth 1 https://github.com/MeltFlexDevs/techdrawai-skills.git cd techdrawai-skills ./setup ``` More options in [INSTALL.md](./INSTALL.md). Agent-driven install, to paste into your agent: [INSTALL_FOR_AGENTS.md](./INSTALL_FOR_AGENTS.md). ## Authenticate Programmatic access is part of the **Studio** plan. Once you are subscribed, the simplest way to sign in is the browser flow, which mints a key from your session and hands it back over loopback so you never copy or paste a secret: ```bash npx -y techdrawai-mcp auth login ``` Or create one by hand at **[techdrawai.com/app](https://techdrawai.com/app?view=settings) โ Settings โ API keys** and export it: ```bash export TECHDRAWAI_API_KEY="tda_sk_..." ``` The key is shown exactly once at creation. Only its SHA-256 is stored, so nobody can recover it afterwards, including us. An account may hold five live keys and revoking one takes effect on the next request. ## Skills | Skill | Invoke | What it covers | | --- | --- | --- | | [`techdrawai-drafting`](./skills/techdrawai-drafting/SKILL.md) | `/techdrawai:drafting` | Photo to dimensioned technical drawing. Drafting standard, sheet size, projection angle, drawing type, views, and the measurements that anchor the scale. | | [`techdrawai-cad`](./skills/techdrawai-cad/SKILL.md) | `/techdrawai:cad` | Everything downstream of the drawing: DXF and DWG at true size, 3D reconstruction, and product renders. | ## Tools | Tool | What it does | Cost | | --- | --- | --- | | `generate_technical_drawing` | Photo to a dimensioned, standards-compliant technical drawing | 3 credits | | `image_to_dxf` | Any image to real CAD contours as DXF, optionally DWG | Free | | `render_product` | Technical drawing to a photorealistic product render | 3 credits | | `photo_to_3d` | Photo to a textured 3D mesh, GLB plus FBX, OBJ, USDZ, STL | 3 credits | | `identify_product` | Name the object in a photo | Free | | `check_credits` | Balance, plan, and what each operation costs | Free | Failed generations are refunded automatically, so an agent that retries a bad prompt does not quietly drain the balance. Every tool writes its result to disk (`./techdrawai-output/` unless you pass `output_path`) and returns the path rather than the bytes. A technical drawing is a megabyte-scale image, and pushing that through the protocol would burn the agent's context on something it usually just hands to the next tool. ## What it looks like in practice > **You:** Here is a bracket, `~/photos/bracket.jpg`. It is 120 mm across. I need a DXF for the laser cutter. ``` [identify_product] โ "steel wall bracket" [generate_technical_drawing] product_name: "steel wall bracket" measurements: [{ value: "120", unit: "mm", position: "overall width" }] standard: ISO ยท paper_size: A3 ยท drawing_type: working โ ./techdrawai-output/drawing-2026-07-27_15-04-11.png 3 credits [image_to_dxf] width_mm: 120 โ ./techdrawai-output/drawing-2026-07-27_15-04-11.dxf 34 contours, free ``` The DXF arrives at true size, so it goes straight to the cutter without rescaling. More patterns in [COOKBOOK.md](./COOKBOOK.md). ## One measurement changes everything Without a real measurement the dimensions are the model's best estimate and are marked nominal. With even one, every other feature is scaled proportionally from it and the whole drawing becomes internally consistent and manufacturable. If a user has not given one, ask for it. It is the single biggest quality lever in the whole workflow. ## The CLI The same package is a command-line tool when you run it with arguments instead of letting an agent speak MCP to it: ```bash techdrawai draw -i bracket.jpg --measure 120:"overall width" --paper A3 techdrawai dxf -i drawing.png --width-mm 120 --dwg techdrawai model3d -i bracket.jpg --detail high ``` Full reference at [techdrawai.com/cli](https://techdrawai.com/cli). ## Documentation - [API reference](https://techdrawai.com/api): every endpoint, request and response - [CLI](https://techdrawai.com/cli): every command and flag - [MCP](https://techdrawai.com/mcp): client-by-client setup - [COOKBOOK.md](./COOKBOOK.md): worked examples - [CONTRIBUTING.md](./CONTRIBUTING.md) ## Licence MIT.
