One problem, met repeatedly.
Olsyn builds spatial software for commercial property: the systems that hold, render and publish what a building actually is. StudiO is the newest product from that team, and it started as the same observation arriving from every direction at once: the information was never missing. It was in a PDF, in a drawing set, in a title block. It simply was not in a form anyone could use to make a decision.
So the brief was narrow on purpose. Take the plan that already exists and read what it says: the scale, the revision, the thickness of each wall segment and the role it plays, the columns sitting on the drawing’s grid. Then give back something a person can walk through and a market can be sent.
Making the result reviewable was harder than making it look right. Geometry that shows its working lets the person signing off see why the model says what it says, and find the places where the drawing was ambiguous and something had to be decided. That constraint shaped the product more than any feature on it.
