According to the documentation, you must initilize the coordiante space with ACC Web UI.
There is currently a limitation in the BIM 360 Model Coordination application resulting in the API not being accessible on new BIM 360 projects until the first coordination space has been defined by a project administrator. Essentially, the administrative process of creating the first collaboration space initializes the model set service container. If you are running these samples against a new BIM360 project with no coordination spaces, you first need to manually create a coordination space via the Model Coordination Project Admin web UI.
And please use subfolders under the Project Files
to create the model set (i.e. coorindate space). If you still want to use Project Files
as coorindate space
, you must use Project Admin web UI to do so instead.
