This guide explains how to create a Revit model in such a way that it will create a good gbXML file. Many geometry issues with gbXML files can be fixed within Tas but in general the best solution is to fix the issue within the Revit file, as this saves on extra work if the gbXML file is used again or if the Revit file is edited and a new gbXML is exported.
The Revit term “room” will be used throughout, but the rules apply equally to “spaces” in Revit MEP.
The guide also explains how to identify gbXML issues within the Tas 3D modeller, which helps to highlight areas of the Revit file which need work.
