TechDraw AI llms.txt changelog

https://techdrawai.com/llms.txt

− > TechDraw AI is an AI tool for engineers, makers and designers that turns a photo of a physical part into a dimensioned 2D technical drawing (DXF, DWG, PDF), a photo or a technical drawing into a 3D model (GLB, STL, OBJ, FBX, USDZ), and a technical drawing into a photorealistic product render. Free to try; Starter €29/month; Studio €89/month adds 3D models, CAD exports and API/MCP access. It also offers free in-browser file converters (image to DXF, DWG to DXF, STL to STEP and more). Operated b− TechDraw AI does not replace CAD software. It produces the starting file that CAD software cannot make on its own: AutoCAD, Fusion and Inventor cannot trace a photograph, and TechDraw AI hands them a drawing or a mesh to work from.− - [Photo to Technical Drawing](https://techdrawai.com/ai-technical-drawing-generator): Upload a photo or sketch of a part; the AI lays out orthographic views (front, top, side) with dimension lines and an ISO, ANSI or DIN title block. One real measurement, such as a caliper reading, sets the true scale. In the app at https://techdrawai.com/app/drafting.− - [Photo to 3D model](https://techdrawai.com/ai-3d-model-generator): Called Photo to 3D CAD in the app. One photograph of a real object becomes a textured 3D mesh in about two minutes, exported as GLB, STL, OBJ, FBX or USDZ. Studio plan. In the app at https://techdrawai.com/app/cad.− - [Drawing to 3D model](https://techdrawai.com/drawing-to-3d-model): Upload a DWG, a DXF or a picture of a drawing sheet; the views are pictured as an object and rebuilt as a 3D mesh (GLB, STL, OBJ, FBX, USDZ). Works best from three orthographic views. Studio plan. In the app at https://techdrawai.com/app/drawing-to-3d.− - [Text to Technical Drawing](https://techdrawai.com/text-to-technical-drawing): Describe a plate, turned part (shaft, flange, bushing) or angle bracket with its sizes; a language model only parses the sentence into parameters and the dimensioned sheet (true views, hidden lines, sections, ISO 286 fits, title block) is computed from them, with every value the model chose listed as an assumption. PDF, DXF and DWG at true size, SVG, PNG. Free with an account.− - Drawing to Photo: turns a technical drawing into a photorealistic product render, with a choice of style, background and camera angle. Included in Starter and Studio. In the app at https://techdrawai.com/app/rendering.− - [API](https://techdrawai.com/api): REST API for the same tools: photo to drawing, DXF and DWG, STL, 3D meshes and renders. Studio plan.− - [MCP server](https://techdrawai.com/mcp): Use TechDraw AI from Claude, Cursor or Codex over the Model Context Protocol: drawings, DXF, DWG, 3D models and renders from inside an AI agent. Studio plan.− ## Plans and Pricing− - Free: 5 credits on signup, enough for one drawing. Exports carry a watermark and download as PNG.− - Starter: €29/month, or €132/year billed annually (€11/month). 120 credits a month, watermark-free exports, Drawing to Photo renders. PNG export.− - Studio: €89/month, or €588/year billed annually (€49/month). 750 credits a month. Everything in Starter plus Photo to 3D and Drawing to 3D (up to 9 models a month), DXF, DWG, SVG and vector PDF export, and API, CLI and MCP access.− - Credits: a drawing or a render costs 5 credits; a 3D model costs 80 credits. Drawings and 3D models draw on the same monthly credits.− - Discount: the code TECHDRAWAI20 takes 20% off the first payment at checkout, on monthly or annual billing (the first month, or the whole first year).− - Prices above are in euros. The site and checkout show a fixed local price in USD, GBP, CHF, PLN, CZK, SEK, NOK, DKK, CAD or AUD. Tax is calculated for the buyer's country at checkout; payment runs through Stripe.− - [See plans](https://techdrawai.com/app/subscription)− ## Key Facts− - Product: TechDraw AI, operated by MeltFlex s.r.o., Bratislava, Slovakia.− - Inputs: photos (JPG, PNG, HEIC, WebP), sketches, scans, screenshots, and DWG or DXF files for Drawing to 3D.− - 2D outputs: dimensioned multi-view technical drawings with title blocks and GD&T symbols; DXF, DWG, SVG and vector PDF on Studio, PNG on every plan.− - 3D outputs: textured triangle meshes as GLB, STL, OBJ, FBX and USDZ. STEP comes from the free STL to STEP converter on the same site.− - Speed: a 3D model takes about two minutes.− - Users: over 156,000 people generating technical drawings with AI.− ## Limits, Stated Plainly− - A single photo cannot reveal true size. Drawings are scaled from one measurement you supply; 3D models come back at an arbitrary size until you scale them against a known dimension.− - The 3D output is a mesh, not a parametric CAD solid: no feature tree, no editable sketches. It suits 3D printing, rendering, AR and game engines. For an editable part in Fusion, SolidWorks or Inventor, import the DXF from the drawing tool and extrude or revolve it, or model against the mesh.− - Drawing to 3D reconstructs the shape the views describe; it does not read dimension values, and features hidden in every view (blind pockets, internal bores) come back solid.− - Fine detail (threads, knurling, small text, thin wire) is approximated in 3D. Anything that must fit another part should be measured and modelled.− ## Use With Autodesk Software− - AutoCAD and AutoCAD LT: open the DWG or DXF from TechDraw AI natively, on named layers, with the views, dimension lines and title block already on the sheet.− - Fusion and Inventor: insert the DXF into a sketch, then extrude or revolve it into a parametric solid; the STL or OBJ mesh imports as a reference body.− - Maya and 3ds Max: FBX and OBJ meshes from Photo to 3D and Drawing to 3D import directly.− - AI agents: connect Claude, ChatGPT or Gemini to AutoCAD or Revit through MCP; the guides below show each setup.− - [TechDraw AI + AutoCAD](https://techdrawai.com/techdraw-ai-and-autocad-workflow): Export DWG and just open it. AutoCAD can't trace a photo, so this is the half it was missing.− - [TechDraw AI + Fusion 360](https://techdrawai.com/techdraw-ai-and-fusion-360-workflow): Insert the DXF into a Fusion sketch, then extrude or revolve it into a parametric model.− - [TechDraw AI + Inventor](https://techdrawai.com/techdraw-ai-and-inventor-workflow): Import the DXF into a sketch, extrude or revolve it, then drive a production drawing and BOM.− - [How to Connect Gemini 4 Argon to AutoCAD (MCP, 2026)](https://techdrawai.com/blog/connect-gemini-4-argon-to-autocad): We ran Gemini 4 Argon through an AutoCAD MCP server 12 times. The Antigravity setup, what it drew exactly, and the 3.25 mm error it made every time.− - [How to Connect ChatGPT to Revit (GPT-6 Astra, 2026)](https://techdrawai.com/blog/connect-chatgpt-to-revit): Autodesk's official Revit MCP server, the community server behind the Astra videos, and the one command that registers either with ChatGPT. What we ran, and what we did not.− - [How to Connect Claude to Revit (MCP, 2026)](https://techdrawai.com/blog/connect-claude-to-revit): Autodesk's Revit MCP server is a 2027.2 tech preview. We read the community servers' code and tested what Claude gets out of a real RVT file.+ > TechDraw AI is AI for technical drawings and CAD. It turns a photo, a sketch or a typed description of a part into a dimensioned engineering drawing (DXF, DWG, PDF) and into a 3D CAD model (STL, OBJ, GLB, FBX, USDZ), and a 2D drawing into a 3D model. Free to try; Starter €29/month; Studio €89/month. Over 156,000 users. Operated by MeltFlex s.r.o., Bratislava, Slovakia.+ It does not replace CAD software; it makes the file CAD software cannot start from. AutoCAD, SolidWorks or Fusion cannot turn a photograph or a sentence into geometry. TechDraw AI hands them a drawing or a mesh to work from.+ - [Photo to Technical Drawing](https://techdrawai.com/): Photo or sketch of a part in, a multi-view drawing out: front, top and side views, dimension lines, GD&T symbols, an ISO, ANSI or DIN title block. One real measurement (a caliper reading) sets the true scale. Exports DXF, DWG, SVG and vector PDF on Studio; PNG on every plan. App: https://techdrawai.com/app/drafting.+ - [Text to Technical Drawing](https://techdrawai.com/text-to-technical-drawing): Describe a plate, a turned part (shaft, flange, bushing) or an angle bracket with its sizes. The language model only parses the sentence into parameters; the sheet is computed from them (true projections, hidden lines, sections, ISO 286 fits), and every value it had to choose is listed as an assumption, never drawn as if given. PDF, DXF and DWG at true size, SVG, PNG. Free with an account.+ - [Photo to 3D CAD Model](https://techdrawai.com/ai-cad-model-generator): One photo of a real object becomes a textured 3D model in about two minutes. STL, OBJ, GLB, FBX, USDZ.

Studio.+ ## What It Cannot Do+ - A photo has no scale. Drawings take their scale from one measurement you give; 3D models come back at an arbitrary size until scaled against a known dimension.+ - The 3D output is a mesh, not a parametric solid: no feature tree, no editable sketches. Right for 3D printing, rendering, AR and game engines. For an editable part, import the DXF from a drawing tool into Fusion, SolidWorks or Inventor and extrude or revolve it. STEP is available through the free STL to STEP converter, still as faceted geometry.+ - Drawing to 3D rebuilds the shape the views show; it does not read dimension values, and features hidden in every view (blind pockets, internal bores) come back solid.+ - Threads, knurling, small text and thin wire are approximated in 3D.

Free to try; Starter €29/month; Studio €89/month adds 3D models, CAD exports and API/MCP access. It also offers free in-browser file converters (image to DXF, DWG to DXF, STL to STEP and more). Operated b+ TechDraw AI does not replace CAD software. It produces the starting file that CAD software cannot make on its own: AutoCAD, Fusion and Inventor cannot trace a photograph, and TechDraw AI hands them a drawing or a mesh to work from.+ ## AI Tools+ - [Photo to Technical Drawing](https://techdrawai.com/ai-technical-drawing-generator): Upload a photo or sketch of a part; the AI lays out orthographic views (front, top, side) with dimension lines and an ISO, ANSI or DIN title block. One real measurement, such as a caliper reading, sets the true scale. In the app at https://techdrawai.com/app/drafting.+ - [Photo to 3D model](https://techdrawai.com/ai-3d-model-generator): Called Photo to 3D CAD in the app. One photograph of a real object becomes a textured 3D mesh in about two minutes, exported as GLB, STL, OBJ, FBX or USDZ. Studio plan. In the app at https://techdrawai.com/app/cad.+ - [Drawing to 3D model](https://techdrawai.com/drawing-to-3d-model): Upload a DWG, a DXF or a picture of a drawing sheet; the views are pictured as an object and rebuilt as a 3D mesh (GLB, STL, OBJ, FBX, USDZ). Works best from three orthographic views. Studio plan. In the app at https://techdrawai.com/app/drawing-to-3d.+ - Drawing to Photo: turns a technical drawing into a photorealistic product render, with a choice of style, background and camera angle. Included in Starter and Studio. In the app at https://techdrawai.com/app/rendering.+ - [API](https://techdrawai.com/api): REST API for the same tools: photo to drawing, DXF and DWG, STL, 3D meshes and renders. Studio plan.+ - [MCP server](https://techdrawai.com/mcp): Use TechDraw AI from Claude, Cursor or Codex over the Model Context Protocol: drawings, DXF, DWG, 3D models and renders from inside an AI agent. Studio plan.+ ## Plans and Pricing+ - Free: 5 credits on signup, enough for one drawing. Exports carry a watermark and download as PNG or SVG.+ - Starter: €29/month, or €132/year billed annually (€11/month). 120 credits a month, watermark-free exports, Drawing to Photo renders. PNG and SVG export.+ - Studio: €89/month, or €588/year billed annually (€49/month). 750 credits a month. Everything in Starter plus Photo to 3D and Drawing to 3D (up to 9 models a month), DXF, DWG and vector PDF export, and API, CLI and MCP access.+ - Credits: a drawing or a render costs 5 credits; a 3D model costs 80 credits. Drawings and 3D models draw on the same monthly credits.+ - Discount: the code TECHDRAWAI20 takes 20% off the first payment at checkout, on monthly or annual billing (the first month, or the whole first year).+ - Prices above are in euros.

STEP comes from the free STL to STEP converter on the same site.+ - Speed: a 3D model takes about two minutes.+ - Users: over 156,000 people generating technical drawings with AI.+ ## Limits, Stated Plainly+ - A single photo cannot reveal true size. Drawings are scaled from one measurement you supply; 3D models come back at an arbitrary size until you scale them against a known dimension.+ - The 3D output is a mesh, not a parametric CAD solid: no feature tree, no editable sketches. It suits 3D printing, rendering, AR and game engines. For an editable part in Fusion, SolidWorks or Inventor, import the DXF from the drawing tool and extrude or revolve it, or model against the mesh.+ - Drawing to 3D reconstructs the shape the views describe; it does not read dimension values, and features hidden in every view (blind pockets, internal bores) come back solid.+ - Fine detail (threads, knurling, small text, thin wire) is approximated in 3D. Anything that must fit another part should be measured and modelled.+ ## Use With Autodesk Software+ - AutoCAD and AutoCAD LT: open the DWG or DXF from TechDraw AI natively, on named layers, with the views, dimension lines and title block already on the sheet.+ - Fusion and Inventor: insert the DXF into a sketch, then extrude or revolve it into a parametric solid; the STL or OBJ mesh imports as a reference body.+ - Maya and 3ds Max: FBX and OBJ meshes from Photo to 3D and Drawing to 3D import directly.+ - AI agents: connect Claude, ChatGPT or Gemini to AutoCAD or Revit through MCP; the guides below show each setup.+ - [TechDraw AI + AutoCAD](https://techdrawai.com/techdraw-ai-and-autocad-workflow): Export DWG and just open it. AutoCAD can't trace a photo, so this is the half it was missing.+ - [TechDraw AI + Fusion 360](https://techdrawai.com/techdraw-ai-and-fusion-360-workflow): Insert the DXF into a Fusion sketch, then extrude or revolve it into a parametric model.+ - [TechDraw AI + Inventor](https://techdrawai.com/techdraw-ai-and-inventor-workflow): Import the DXF into a sketch, extrude or revolve it, then drive a production drawing and BOM.+ - [How to Connect Claude to Revit (MCP, 2026)](https://techdrawai.com/blog/connect-claude-to-revit): Autodesk's Revit MCP server is a 2027.2 tech preview.
