Most engineering buyers know the pattern. You hire a design firm. The drawings land. Then you find a manufacturer who reads the drawings differently. Then an automation contractor who needs the manufacturer to make changes. Three vendors, three contracts, three opinions on why something doesn't fit.
AptoCAD was founded to collapse that chain. One team designs the machine, manufactures it in our workshop, and writes the automation that makes it run. The same engineer who modelled a part is responsible for it when it gets welded. The same person who specified the PLC writes the code.
What sounds like an obvious model is surprisingly rare. It works because we kept the team small enough that everyone can hold every project in their head - and because we refuse to take on more than we can deliver well.
