About this app

Turn a photo into a technical drawing.

Point your phone at a product, measure it on screen, and TechDraw AI drafts a dimensioned 2D technical drawing on a proper ISO or ANSI sheet: front, top, side and isometric views, a filled in title block, and the callouts your trade actually needs.

SIX KINDS OF DRAWING, EACH SET UP FOR THE JOB

Furniture. Photograph a table, cabinet or chair and get a shop drawing the bench can build from, with joinery detail at the joints and a parts list.

Clothes and Fashion. Lay the garment flat, shoot it, and get a technical flat ready for a tech pack, with seam lines and callouts at the standard points of measure.

Machine Parts. One caliper measurement anchors the scale, and the drawing comes back with tolerance callouts, hole diameters and surface finish symbols.

Sheet Metal. Brackets, panels and enclosures drawn with material thickness, bend lines, bend direction and a flat pattern showing the developed length.

Woodworking. Shelves, jigs and projects with a cut size for every part, a cut list, and small parts printable at 1:1 as a template.

3D Printing. Dimension a printed part to check it, remake it in CAD, or document the design, with wall thickness and mating clearances called out.

MEASURE ON THE PHOTO

Drag a line across any edge and type its real size. One known dimension sets the scale for the whole drawing, so everything else comes back proportionally correct. Add up to three photos of the same object from different angles for a more precise drawing.

MORE THAN DRAWINGS

Photo to 3D CAD. One photo of an object becomes a 3D model you can orbit, then download as GLB, STL, OBJ, FBX or USDZ.

Text to drawing. Describe a part and its sizes in a sentence and get a dimensioned drawing, no photo needed.

Ask AI to edit. Say what to change, like "make the hole 12 mm", and the drawing is updated as a new version.

Drawing to photo. Turn a technical drawing back into a photoreal product image.

EXPORT AND SHARE

Full resolution PNG and a true size PDF you can print. With Pro, export the sheet as DXF, DWG or SVG for AutoCAD, Fusion, SolidWorks, Illustrator or a laser cutter.

FIX A WRONG NUMBER WITHOUT STARTING OVER

Tap any dimension that came back wrong and type the right one. The fix is saved as a new version.

What’s new

New: Photo to 3D CAD. Take one photo of an object and get a 3D model in a few minutes. Orbit it in the app and download it as GLB, STL, OBJ, FBX or USDZ for 3D printing, CAD, AR and rendering. Start from your own photo or one of the examples. Your 3D models are saved on your Board next to your drawings.

Photo to 3D CAD comes with the new TechDraw AI CAD plan: 20 models every week, separate from Pro.
