The next release of Design Master HVAC, currently being beta tested, includes a new feature to export the 3D ductwork in IFC format.
IFC standards for Industry Foundation Classes. It is an open, vendor-neutral, standardized file format for exchanging building information models (BIM).
Exporting our ductwork in IFC format allows them to import better into Revit. You can use the model to do collision detection with our ductwork and the architectural model in Revit. Previously, it was necessary to export both models to another program, such as Navisworks, to do the collision detection.
Adding full IFC export functionality to all three programs is high on our list of features to implement. Adding support for exporting ductwork is the first step toward achieving this goal. Once we have finished, Design Master HVAC, Electrical, and Plumbing will be completely compatible with projects that require BIM or Revit.
