I’m trying to export a Revit model as a GLTF and have it contain user defined properties. At the moment I’m using Visionworkplace Software Solutions’ GLTF Converter for Autodesk® Revit®. It doesn’t give any options when exporting to get custom properties, so I’m not sure how or where is gets the information it does (it gets the name of the objects). Is there another GLTF exporter that does allow for you to choose what properties are exported? Or is there a way in Revit to indicate which properties you want exported?
