Issue with GLTF translation (on assembly)

  We have an issue with the translation API using the GLTF format. We are getting the error below from the API explorer. Note that all other format successfully completes using the same parameters.

    Hi Andre,

    This looks like a bug on our end. I'm investigating it and I'll let you know what I find.

    I have also experienced this problem. Export through GUI works just fine, other formats have no issues translating. It's just GLTF that fails to translate.

    I'm getting the same issue with the Assemblies translation API.
    The interface is apparently using the Document translation API instead (don't know if it's documented), export works fine if you pass the correct parameters:

    This is the parameter list I pass to this endpoint:


                    "elementId": {assembly_id},
                    "formatName": 'GLTF',
                    "flattenAssemblies": False,
                    "yAxisIsUp": False,
                    "triggerAutoDownload": False,
                    "storeInDocument": False,
                    "grouping": True,
                    "configuration": {encoded_config},
                    "resolution": "coarse",
                    "distanceTolerance": 0.00024,
                    "angularTolerance": 0.2181661564992912,
                    "maximumChordLength": 10,

    With a POST on this endpoint and body, the script can correctly download the GLTF 3D model
