One pipeline from the camera to CAD.
LensCAD does not stack an image editor on top of a drawing app. Correction, scale, tracing, editing and export are one flow, and the scale you set in step two is the scale of the file you leave with.
Three steps, and two ways out.
Every part goes through the same three steps. You can leave after the second with a scaled photo to trace in your own CAD, or stay for the trace and the export.
Make the photo measurable.
Upload a phone photo of any physical object. LensCAD reads the camera data and removes lens distortion, then you fix perspective from four corners, two perpendicular lines, a circle, or the printed reference sheet in one tap. Scale comes from a known dimension, a ruler in frame, two rulers, or the same sheet. Correction and scale →
Smart Trace draws the part.
Press Run and Smart Trace draws the whole part: outer profile, holes and interior features, each on the real edge in the photo and named on its own layer. Aim it with a brush or a sentence. Refine anything with the editor. Smart Trace → · CAD editor →
Leave with usable CAD.
Download a 1:1 DXF with dimensions and layers, ready for any CAD program. Photograph two or three sides and press 3D for a true solid you can draw on, fillet and build over, saved as STEP, 3DM, STL, OBJ with your photos, or 3D DXF. 3D models →

A full drawing toolkit that knows about the photo underneath.
Read more →Scan mode and Draw mode.
Scan mode takes a photo through the full correction pipeline: photo, lens fix, perspective, scale, trace, dimension. Each of the last three is an exit point, so you can export a scaled image to trace in your own CAD, geometry at 1:1, or geometry with dimensions.
Draw mode skips the photo entirely. Set the canvas size (Letter, Tabloid, A3, A4 or custom) and units, draw with the full toolset, dimension, and export the same 1:1 DXF. Or start from a DXF you already have: import it from the File menu and keep drawing.
The same app on both.
LensCAD runs in the browser with nothing to install. On a phone or tablet it works in landscape and portrait with a full touch interface and the complete toolset. On a desktop it behaves like a native CAD application: keyboard shortcuts, a command line where you type a tool's name, precise mouse control, snap and guide systems.

HEIC photos from an iPhone upload as they are, and a 12 MP frame arrives at full resolution rather than being shrunk on the way up, which is where the fine detail lives.
