Your Napkin Sketch, Clean CAD File in 15 Seconds

Turn hand-drawn floor plans, whiteboard sketches, and rough concepts into production-ready, dimension-accurate CAD files instantly.

The Problem

Great Ideas Die in the Translation from Sketch to CAD

Every architect knows the moment: a brilliant concept sketched on a napkin, a whiteboard, or the back of an envelope. But between that sketch and a usable CAD file lies hours of tedious manual drafting.

By the time the sketch becomes a CAD file, the momentum is gone. The design review is next week. The client meeting is tomorrow. The junior architect assigned to digitise it has three other projects. Great ideas lose their urgency when they take too long to formalise.

  • Average sketch-to-CAD time: 2-4 hours for a simple floor plan
  • Design iteration slows to the speed of manual drafting
  • Early concepts lack dimensional rigour, leading to rework later
  • Sketches get lost or misinterpreted in the digitisation process

The Solution

Snap a Photo of Your Sketch. Get a CAD File Back.

ArchLab accepts any hand-drawn sketch — napkin, whiteboard, graph paper, tablet drawing — and converts it into a dimensioned, editable CAD file in approximately 15 seconds.

Walls are straightened. Angles are snapped to true values. Dimensions are derived from the geometric relationships in your sketch. The result is a production-ready DXF/DWG file that opens directly in your CAD software.

  • 15-second conversion from photo to CAD
  • Wall straightening and angle correction
  • Automatic door, window, and opening detection
  • Instant design iteration — sketch, scan, refine, repeat
Workflow

From Sketch to CAD in Three Steps

Step 1

Sketch Your Idea

Draw on anything — napkin, whiteboard, graph paper, or tablet. Include walls, doors, and windows as you normally would.

Step 2

Photograph and Upload

Take a photo with your phone or scan with any scanner. Upload to ArchLab. The AI analyses the sketch immediately.

Step 3

Download Clean CAD

Get a dimensioned DXF/DWG file with straightened walls, snapped angles, and layer-separated elements. Open in any CAD software.
