free parameter llc
Generative CAD
Decks, kitchens, baths, trusses, masonry: described by parameters, drawn to the sheet, checked by code.
We write the tools we wished we had on site.
Free Parameter is a small team of engineers, designers and builders. We turn design intent into geometry you can build from, and we ship it as software.
Agents that draw
Ask for a plan set in plain words. Agents pick the generator, fill the parameters, draft the sheets and show their work.
From site to sheet
Measured on site, modeled in the studio, delivered as DXF, IFC, PDF and a 3D model in the browser.
our platform
Cadnat. CAD + BIM, generated.
A native CAD and BIM workstation with generators built in, a command line that understands you, and an agent port so software can draw too. Launching soon.
