TechDraw AI is a web-based AI image-to-CAD converter that turns a photo or sketch of any part into a clean, dimensioned 2D technical drawing in seconds, ready to export as DXF, DWG, SVG, or PDF.
What is TechDraw AI?
TechDraw AI is a browser-based tool that uses artificial intelligence to convert images—photos, hand sketches, JPGs, PNGs, or scans—into technical drawings with real dimensions. Upload an image, set one known measurement, and the AI generates orthographic views (front, top, side) with dimension lines, a title block, and GD&T symbols, then exports to DXF, DWG, SVG, or PDF. It runs entirely in the web, requiring no CAD license or installation. The product is developed by TechDraw AI and is trusted by over 213,000 users worldwide, with a 4.8/5 rating from 1,200+ reviews. You can start creating free at techdrawai.com/create or access the app directly at techdrawai.com/app.
Key Features
TechDraw AI's core value is turning images into dimensioned drawings without manual CAD work. Its features cover the entire workflow:
- Photo-to-CAD conversion — Accepts JPG, JPEG, PNG, WebP, HEIC, TIFF, BMP, GIF, and AVIF files, including photos of physical parts, hand sketches, and scanned drawings.
- Real-world scale from one measurement — Set a single length on the uploaded image, and every dimension in the drawing is calculated from it, so line work matches the actual part instead of guessing from pixels.
- Orthographic views with automatic dimensioning — The AI arranges front, top, and side views, places dimension lines, and applies GD&T symbols automatically, producing sheets that meet ISO, ANSI, and DIN standards.
- Multiple export formats — Export to DXF, DWG, SVG, and PDF; files open in AutoCAD, SolidWorks, Fusion, FreeCAD, and other CAD/CAM programs.
- Free browser-based converters — In addition to the full app, there are free online Image to DXF, PNG to DXF, and JPG to DXF converters that run directly in the browser without signup.
- BOM and cutting-list generation — From a single photo, the AI can generate a bill of materials or a cutting list, and it keeps views and BOM in sync when dimensions change.
- Batch & pipeline generation — Paid plans include batch and pipeline generation for processing multiple drawings automatically.
Who should use TechDraw AI?
TechDraw AI is designed for anyone who needs production-ready technical drawings but doesn't want to redraw from scratch. It suits these roles:
- Mechanical engineers — Use TechDraw AI to document existing parts by photographing them and exporting dimensioned DXF/DWG files for revision or handoff.
- Furniture makers and woodworkers — Turn hand sketches or photos of pieces into cutting lists and BOMs, and produce section views for client approvals.
- Fabricators and machine shops — Convert a physical part into a production-ready technical drawing with correct tolerances and GD&T, ready to send to CNC or laser cutting.
- Makers and hobbyists — Create patent-style figures or document workshop jigs without learning full CAD software.
Use cases
Here are the concrete workflows TechDraw AI handles well:
- Document a replacement part — Photograph the broken part, set a reference measurement, and receive a full dimensioned drawing to manufacture a replica.
- Convert a hand sketch to CAD — Sketch on paper, photograph it, and let TechDraw AI clean up the lines and output an editable DXF/DWG file.
- Prepare files for CNC or laser cutting — Export DXF/SVG directly from a photo of the part, avoiding redrawing or manual tracing.
- Create assembly drawings with BOM — Upload a photo of an assembly to generate an exploded view and a complete bill of materials in one go.
How does TechDraw AI work?
TechDraw AI follows a simple workflow:
- Upload your object — Drop in a photo, sketch, or image (JPG, PNG, HEIC, etc.).
- Choose type and measurements — Pick the drawing type and units, then set the real scale and lengths of the object.
- Get your drawing — Receive a clean, dimensioned, standards-compliant technical drawing that is ready to export.
Behind the scenes, the AI reads the part in your photo and places dimension lines based on the real measurement you set, rather than tracing pixels like typical image converters.
Pricing
TechDraw AI is freemium. You can start creating for free, with paid tiers at Starter €20/mo and Studio €50/mo. A launch discount code TECHDRAWAI20 gives 20% off. Free users can generate and export drawings; paid plans add batch and pipeline generation.
FAQ
How do I convert an image to CAD?
Upload the image—a photo, hand sketch, JPG, or PNG—to TechDraw AI. The AI traces the part, lays out orthographic views, and places dimensions. You set the real scale with one measurement, then export the drawing as DXF or DWG and open it in AutoCAD, SolidWorks, Fusion, or another CAD program.
Can AI create a technical drawing?
Yes. TechDraw AI generates a clean, dimensioned technical drawing from a photo of your part, complete with orthographic views and a title block, in seconds. You provide the image, set the real measurements, and the AI does the drafting.
How accurate are AI-generated technical drawings?
Accuracy depends on the measurements you provide. TechDraw AI does not guess size from pixels; it asks you to set the real scale and key lengths, then builds every dimension from those values. This keeps numbers tied to your actual part rather than an estimate.
Is there a free AI technical drawing tool?
Yes. TechDraw AI offers a free plan that lets you create and export technical drawings without a credit card or CAD license. For heavier workloads, paid plans (Starter and Studio) add batch and pipeline generation.
