We use the autodesk ACE collection, specifically Revit. I.e. we design in 3D from the start. By linking the models of all design parties, you can resolve errors and clashes in the design phase, greatly reducing failure costs. We work with BIM (Building Information Model).
For BIM engineering and 3D design for your theatre or music venue or cultural center PBTA is the right company to turn to (including advice / design / tendering / procurement / quick scan).
