Design Master AquaBIM review

AquaBIM takes a different approach from the other tools here. It is a Revit add-in that connects an AI assistant, such as Claude, to the open Revit model and gives it real Revit tools. You describe the work in plain language and it creates domestic water and sanitary runs on real Revit pipe, ties lavatories, water closets and equipment into the right system, points out disconnected fixtures and gaps, and reroutes or resizes piping. A dedicated license is $50 a month or $500 a year, and a floating license shared across a team is $2,000 per seat a year. There is a 14-day trial with no credit card. The limits are clear on Design Master's own page: fixture unit counts, pipe and vent sizing, pressure and flow and code compliance are listed as things users can request for future versions, so today it speeds up modeling rather than engineering calculations. It also needs a Revit seat.
