Hi Espen,
Concerning your first question, I have a solution but keep in mind I never worked with BIM360 and had to create a dummy project to conduct tests. Autodesk has released a ‘Desktop connector’, which upon install allows you to have access to your files in your browser (Google Drive/Dropbox style), and therefore a direct filepath. It doesn’t seem to download the files on your computer unless needed and worked well for me.
For your second question, I updated the nodes. A new input allows you to specify strings that appear in the names of the worksets you wish to keep closed. In the following example, every workset containing “Shared” or “ARC” will remain closed.
Edit : the nodes are maintained in the Morpheus package as of now.
