Easier than CAD

Set the scale, select a tool, draw naturally to place walls, furniture, beds, or a whole site plan in feet and inches or metric.

Better than a napkin

Rectangles, rounded rectangles, ellipses, lines, polygons, arcs, freehand, text, and dimension strings that label themselves.

See what fits

Test the idea before you buy materials, move the couch, submit to the HOA, or start building.

Print to scale

Export a vector PDF, SVG, or PNG. A printed PDF measures accurately with a scale ruler.

“I missed the simplicity of MacDraw but didn’t want to invest in an expensive CAD application. Nothing offered the straightforward drawing tools I once relied on, so I found myself returning to pencil and graph paper, even to design the shed I submitted to the zoning office. Frustrated that a task once so simple had become unnecessarily complicated, I decided to build the tool I wished I still had.”

Simple by design. Built for real projects. Free to use.
