# TechDraw AI

> TechDraw AI turns a photo of a physical part into a dimensioned, manufacturing-ready 2D technical drawing. The AI lays out the orthographic views and dimension lines; you anchor the scale with one real caliper measurement, then export DXF, DWG, SVG or PDF. A single photo cannot reveal a part's true size on its own, so one measured reference is what makes the drawing manufacturable.

## Answers
- [Can AI create technical drawings?](https://techdrawai.com/answers/can-ai-create-technical-drawings): Yes. AI can turn a photo of a part into a clean, dimensioned technical drawing with orthographic views and a title block in seconds. The reliable workflow is for the AI to do the drafting while a person confirms the real measurements, because a single photo cannot reveal a part's true size on its own.
- [How do I convert a photo into a technical drawing?](https://techdrawai.com/answers/convert-photo-to-technical-drawing): Upload a clear, straight-on photo of the part, let the AI lay out the views and dimension lines, then enter one real measurement to set the scale and confirm the dimensions that matter. A high-contrast photo with the part filling the frame gives the best result.
- [Can AI turn a sketch into a CAD drawing?](https://techdrawai.com/answers/convert-sketch-to-cad-drawing): Yes. A hand sketch works the same as a photo: the AI cleans up the lines, straightens the proportions and produces a tidy, dimensioned drawing you can export to CAD. As with a photo, you set one real measurement so the result is to scale rather than approximate.
- [Can ChatGPT make technical drawings?](https://techdrawai.com/answers/can-chatgpt-make-technical-drawings): ChatGPT and general image generators can make a picture that looks like a technical drawing, but it is not drawn to scale, the dimensions are invented, and you cannot export it to a CAD file. For a drawing a workshop can use, you need a tool that anchors every dimension to real measurements and exports DXF, DWG or PDF.
- [How do I convert an image to a DXF file for CNC or laser cutting?](https://techdrawai.com/answers/convert-image-to-dxf): Use a tool that vectorizes the image into clean lines and arcs, then exports DXF. DXF is the standard 2D format for laser, plasma, waterjet and CNC routing. For best results start from a high-contrast image, and pair the DXF with a PDF drawing if the part has tolerances or notes.
- [How accurate are AI-generated technical drawings?](https://techdrawai.com/answers/are-ai-technical-drawings-accurate): They are as accurate as the measurements you give them. Many tools guess the size from the pixels in a photo, which is unreliable. The accurate approach is to set one or more real measurements yourself so every dimension is built from your part, then verify the values that control fit before you manufacture.
- [Will a machine shop accept an AI-generated drawing?](https://techdrawai.com/answers/do-machine-shops-accept-ai-drawings): Yes, as long as the sheet is complete. Shops care about the content, not who drafted it. If it has correct views, clear dimensions, stated tolerances and a full title block, it quotes and machines like any other drawing. Confirm the critical dimensions yourself before you send it.
- [Is there a free AI technical drawing tool?](https://techdrawai.com/answers/free-ai-technical-drawing-tool): Yes. You can start creating technical drawings with TechDraw AI for free, with no credit card and no CAD license required. Free tools are great for getting a clean, dimensioned drawing quickly, as long as you set the real measurements so the result is to scale.
- [How much does a technical drawing cost?](https://techdrawai.com/answers/how-much-does-a-technical-drawing-cost): A single 2D technical drawing typically costs $45 to $600 or more from a freelancer or drafting service, depending on complexity. Simple parts run $150 to $300; drawings with full GD&T and tolerances cost more. Freelance drafters charge $50 to $150 per hour, and rush jobs add roughly 50%. AI tools that draft from a photo cut this to minutes.
- [DXF vs DWG: which should I use?](https://techdrawai.com/answers/dxf-vs-dwg-which-to-use): Use DXF when you are sending part geometry to a machine shop, laser or waterjet — it is an open, plain-text format nearly every CAD and CNC tool reads. Use DWG when you are editing in AutoCAD and want layers, blocks and 3D preserved in a smaller binary file. Rule of thumb: DWG is your working master, DXF is the handoff.
- [Can you get dimensions from a photo?](https://techdrawai.com/answers/get-dimensions-from-a-photo): Yes, but only with a scale reference. A photo alone cannot reveal a part's true size, because a small object up close and a large one far away produce the same pixels. Once you give one known measurement (a reference object or a caliper reading), software scales everything else. With a square-on shot, accuracy is typically within 1 to 4%.
