About IMSI Design
Pioneering CAD innovation for 30 years.
We make design software for people whose drawings turn into real objects — buildings, parts, furniture, kitchens. Three product families, one long-running promise: the licence you buy keeps working, and the file you drew last decade still opens.
What we build
Professional CAD, priced for the people who use it
Most CAD vendors moved everyone onto mandatory subscription. We did not. TurboCAD, DesignCAD and FloorPlan are still sold as perpetual licences alongside term options, because a one-person shop and a fifty-seat engineering team do not have the same relationship with a recurring bill.
That is also why we keep archived installers online, why upgrade pricing reaches back years rather than months, and why support can still find a key issued a decade ago. Design tools become infrastructure for the people who rely on them, and infrastructure should not disappear on a release schedule.

Copilot Render, sheet-metal unfolding, one multi-language installer.
Precision first
A CAD file is a legal and manufacturing document. Everything we ship is judged on whether the geometry holds up when somebody builds from it.
Ownership, not rental
Perpetual licences stay on the price list. Subscription is an option we offer, not a lever we pull on people who already paid.
Long memory
Archived installers, keys we can still look up, and upgrade paths that reach back years — because your drawings outlast our release cycle.
