Sheet Metal Drawings& Flat Patterns with AI

Sheet Metal Drawings in three steps
Photograph the part
Shoot the bent bracket, panel or enclosure you need documented, or the flat blank you want to reproduce. Clean edges photograph best.
Set the real size
Choose the drawing type and units, then anchor the scale with one measured dimension and the material thickness so the sheet reads true.
Get drawing and flat pattern
Receive a dimensioned drawing with views, bend lines and a labelled flat pattern, and export the cutting geometry as DXF for the laser, plasma or punch.
From bent part to cut-ready geometry
Sheet metal lives in two states at once: the bent part the customer sees and the flat blank the laser cuts. A proper drawing carries both, formed views with bend lines and a dimensioned flat pattern. TechDraw AI drafts that sheet from a photo, anchored to your measured size and thickness, so a bracket someone hands you at the counter becomes a documented, quotable part in minutes.
One honest note: developed lengths depend on your bend allowance, and that depends on your tooling and material. Treat the generated flat pattern as the drafted starting point and confirm the K-factor against your press brake's numbers before cutting a batch. The DXF export goes straight into your nesting software either way.
Fabrications and their flat patterns
Twenty formed parts and the drawing drafted from each photo, bend lines and developed length included. Open one to drag the photo across the sheet.
Fab shops in 40+ countries document their parts with AI.
“Where was this when I documented my first machine?? Now I run everything through the AI first and export production-ready sheets.”
“quick, easy, accurate. Using it for all my fabrication drawings now.”
“upload a render, pick the views, export the sheet. 20 minutes total.”
“Was redrawing a frame for weeks. Fed the photo into TechDraw and had the full set inmediately. Should have done this first.”
“Boss approved the drawing on the first pass wich never happens lol. Sent it to production same day.”
“Only tool where the title block and standards come out ISO-correct every time. Huge diffrence compared to others.”
“Drew up my whole assembly in one evening. Showed my boss and he tought I outsourced it. Nope, just AI.”
“Tried 4 or 5 CAD tools before this. The line quality here is noticably better and it actually places dimensions correctly wich none of the others did. Game changer.”
Frequently asked questions
Can AI make a sheet metal drawing from a photo?+−
Yes. Photograph the bent part, set one measured dimension and the material thickness, and TechDraw AI drafts a dimensioned drawing with formed views, bend lines and a labelled flat pattern, in the conventions a fab shop expects.
Can I get a flat pattern from a photo of a bent part?+−
Yes. The drawing includes an unfolded flat pattern view with bend lines shown as chain lines. Developed lengths depend on bend allowance, which varies with your tooling and material, so confirm the K-factor against your press brake before cutting a production batch.
Can the DXF go straight to a laser or plasma cutter?+−
Yes. Export the cutting geometry as DXF and import it into your nesting or CAM software like any other cut file. Closed contours and real-world scale are exactly what laser, plasma and waterjet tables need, and both are checked before export.
Does it handle bend allowances and K-factors?+−
The flat pattern is drafted with standard assumptions, and honest advice is to treat it as a starting point: bend deduction is a property of your specific press brake, dies and material. Verify the developed length on the first article before running the batch, as you would with any new flat pattern.
What if I only have the flat blank, not the bent part?+−
That works too, and it is simpler: photograph the flat part, anchor the scale, and export the traced geometry as a dimensioned drawing or a DXF. For quick outline tracing of clean flat parts, the free in-browser image to DXF converter handles it without a signup.
What formats does it export for fabrication?+−
DXF for the cutting table and CAM, DWG for CAD, PDF for quotes and the shop floor, SVG for laser workflows. One drawing exports to all of them.
Same engine, a different rulebook
A flat pattern and a furniture cut list are the same job under different rules: read the object, work out the sizes, write the sheet the next machine can act on. These are the other rulebooks it knows.
Furniture
Shop drawings with joinery detail, real sizes and a cut list.
Clothes & Fashion
Front and back flats with the callouts a tech pack needs.
Machine Parts
Views, tolerances and a DXF your machine shop can quote from.
Woodworking
Plans you can build from, or a 1:1 template to print.
3D Printing
Wall thickness, clearances and fits, checked before you print.
