Turn a photographed floor plan or hand-drawn sketch into a CAD draft you can check, correct and export as DXF. Built for renovation planning, interior layouts and on-site sketch workflows. TRY YOUR OWN DRAWING FIRST Start with included AI trial credits. Compare the result with the original photo, correct a single drawing and export its DXF before deciding whether to upgrade. Single-image correction and 2D DXF export are free; AI recognition uses credits and requires an internet connection. FROM PHOTO TO EDITABLE LAYERS • Import a photo or scan, or capture a sketch with the camera. • Review detected walls, doors, windows, rooms, dimensions and annotations. • Compare with the source image, adjust the drawing and calibrate a known length. • Export layered DXF for continued editing in compatible CAD software. • Keep project history and report problems from the result screen. MEASUREMENTS YOU CAN CHECK Drawings and DXF use mm, cm or m. Calibration input also accepts in and ft and converts them to the selected metric drawing unit. This does not add feet-and-inches DXF output. AI output is a draft: verify dimensions, scale and missing elements against the original before professional use. Recognition quality depends on the source image; no survey accuracy is guaranteed. CLEAR PURCHASE OPTIONS Pro is a one-time purchase for batch tools, additional export formats and workspaces, including 220 AI recognition or repair credits. Permanent Pro access does not mean unlimited AI usage. The 220-credit pack adds AI recognition or repair credits only and does not unlock Pro features. Additional AI usage requires credits. Prices are displayed by the App Store in your storefront currency. Pro can be restored with the same Apple Account. 3D SINGLE-STOREY LAYOUTS Use a reviewed sketch result or import a supported ASCII 2D DXF (LINE and straight LWPOLYLINE, up to 10 MiB). Confirm scale, wall height and wall thickness. Arrange 37 furniture types and room floor finishes in a full-screen studio, with cutaway views, indoor walkthroughs and undo/redo. 3D preview is free; exporting 3D DXF/GLB requires Permanent Pro. Models are visual drafts, not parametric construction models. DWG, curves, blocks and multi-storey modeling are not supported. GLB keeps colors without texture patterns. Layout drafts are saved on this device. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://cad.xinghebit.com/privacy.html

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. Sheets without a watermark, full resolution PNG and a PDF you can print at true size, DXF, DWG and SVG export, and priority rendering when the queue is busy.
