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. The measurements are burned into the image the model sees, and that is what makes the numbers real rather than guessed. Add up to three photos of the same object from different angles for a more precise drawing. MORE THAN DRAWINGS 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, same geometry, real materials. EXPORT AND SHARE Full resolution PNG and a true size PDF you can print. With Pro, export the whole sheet as DXF, DWG or SVG for AutoCAD, Fusion, SolidWorks, Illustrator or a laser cutter. Save to your photo library or share straight from the app. FIX A WRONG NUMBER WITHOUT STARTING OVER Tap any dimension text that came back wrong and type the right one. The fix is saved as a new version, and the original stays there if you want it back. WORKS IN YOUR LANGUAGE English, German, French, Spanish, Italian, Dutch, Czech and Slovak. NO ACCOUNT, NO SIGN UP There is no login. Open the app and make a drawing. Nothing to remember, nothing to verify. TECHDRAW AI PRO A weekly allowance of drawings and renders.

Start your clothing brand without design skills. LineDrop gives you ready-made tech pack templates for streetwear, so you can send a factory a clear, professional spec for your first drop. PICK A TEMPLATE Boxy heavyweight tees, cropped hoodies, crewnecks, varsity and coach jackets, wide cargo pants, sweatpants, cargo shorts, balloon pants, tracksuits, shell jackets, utility vests, skirts, dresses and a structured 6-panel cap, in four styles: boxy minimalist, gorpcore, tactical and Y2K.

SEND IT TO YOUR FACTORY Export a two-page PDF tech pack and share it by email, WhatsApp or Files. FREE SIZE CHART MAKER Turn any template into a size chart for your product page, Instagram or Shopify.

FREE, NO ACCOUNT The vector flat sketch of every template, front and back, with no sign-up and no limit. Save it as a PDF, keep it in Files or mail it to yourself, then open it in Illustrator, Affinity or Figma with the paths intact and put your own graphics on it. Browsing all 32 templates, their size charts and their construction notes is free too, and so is the size chart maker. LINEDROP PRO Pro is the tech pack itself: the graded size chart from XS to XXL with the tolerance a factory is allowed on every measurement, fabric weights and their safe ranges, the bill of materials and the construction notes a factory quotes from — customised and exported as a two-page PDF, and re-exported as often as your sample comes back.
