问题


SVF2 has different objectids/dbids than SVF1. In this SO-Answer, it was advised to use externalId instead of objectid. However, viewer.loadModel(svfUrl,{ids:[dbIds...]}) takes dbIds to load only specified objects. How can I load only specified objects using SVF2 and the https://developer.api.autodesk.com/modelderivative/v2/regions/eu/designdata/:urn /metadata/:guid/properties endpoint? Can I access the svf2 objectIds anywhere or can I use the externalIds when calling Viewer3d::loadModel?

You're right, there's a difference between the "SVF1 dbIDs" and the "SVF2 dbIDs" - the IDs in SVF2 format are "persistent", meaning that in different versions of the same design file, a single ID will reference the same design element (which was not the case in SVF1).

Unfortunately, there are parts of the platform (like the loadModel viewer method and the /modelderivative/v2/regions/eu/designdata/:urn /metadata/:guid/properties endpoint) that have not "caught up" with SVF2 yet. And before those updates are available, you would have to map "between the old and new dbIDs" manually which is itself another, non-trivial task.
