Machine Part Drawings in three steps
Photograph the part
Shoot the part you need documented, a machined component, a worn part you are replacing, or a prototype that never got a print.
Anchor one measurement
Pick the drawing type and units, then enter one real caliper measurement. Every other dimension is scaled from your reference, not guessed from pixels.
Get the working drawing
Receive a dimensioned production drawing with front, top and side views, sensible tolerances and callouts, ready to send to the shop for a quote.
Working drawings a machine shop will actually quote
A shop quotes the sheet, not the part. When a component has no print, someone has to measure it, lay out the views and dimension everything, which is an afternoon of drafting for a part you could photograph in ten seconds. TechDraw AI does the drafting: it reads the geometry from the photo, arranges proper orthographic views with a projection symbol, and anchors every dimension to the caliper measurement you provide.
That covers replacement parts with no documentation, legacy components before reordering tooling, and prototypes that skipped the drawing stage. Export DXF or DWG when the geometry heads into CAD or CAM, and PDF for the quote email. For parts that need reverse engineering from scratch, the guide below walks the whole path.
Engineers and shops in 55+ countries quote from AI-drafted prints.
“My shop foreman asked which drafter made these sheets. It was just me and TechDraw AI lol. Did 3 parts in one afternoon.”
“found a tolerance error my old drawings missed for years. The AI flagged it and fixed the callout automatically.”
“As a mechanical engineer I was skeptical but this speeds up my workflow so much. Clients get drawings AND a parts list right away.”
“I use this for client handovers now. Upload a part, get fully dimensioned views in 10 minutes. They think I have a whole drafting team.”
“Boss approved the drawing on the first pass wich never happens lol. Sent it to production same day.”
“section views that used to take an hour now take seconds. Worth every penny.”
“Only tool where the title block and standards come out ISO-correct every time. Huge diffrence compared to others.”
“Was redrawing a frame for weeks. Fed the photo into TechDraw and had the full set inmediately. Should have done this first.”
Frequently asked questions
Can AI create an engineering drawing of a machined part?+
Yes. Photograph the part and TechDraw AI drafts a working drawing with orthographic views, a projection symbol, dimensions in mm and sensible tolerance and finish callouts. You anchor the scale with one caliper measurement and review the critical values before exporting.
How accurate are the dimensions?+
As accurate as the reference you provide. The AI does not guess sizes from pixels: you enter one real measurement and every dimension is scaled from it, then you confirm the values that carry your design intent. For toleranced features, measure them and set the values explicitly.
Will a machine shop accept an AI-generated print?+
Shops care about the content of the sheet, not who drafted it. If the views are correct, the dimensions complete and the tolerances stated, it quotes and machines like any drawing. You review and confirm the key values before sending, exactly as you would with a junior drafter's sheet.
Can I recreate a drawing for a part that has no documentation?+
Yes, that is the core use case. Legacy parts, worn components you need remade, or supplier parts that arrived without prints: photograph the part, measure the critical features, and get a dimensioned drawing you can send out for quotes instead of shipping the only sample you have.
What formats does it export for machining?+
DXF and DWG for CAD and CAM, PDF for quoting and the shop floor, and SVG where vector graphics are needed. The DXF drops into Fusion, SolidWorks, FreeCAD or your CAM package as real geometry.
Does it handle tolerances and GD&T?+
The drawing includes dimensional tolerances and standard callouts where they make sense, and you can adjust the values that matter. For heavily toleranced GD&T work, treat the sheet as the drafted starting point that you refine, which is still hours faster than starting from a blank sheet.
