Since the Design Summit 21 I've been publishing to the cloud using Vectorworks Service Select. Brilliant! Thought I'd share an experience. Cloud publishing is not possible if your filename has the usual unsupported characters like "&" "-" etc. This also applies to folder names. The error message is "file must be saved to cloud"....so the unsupported characters prevent uploading even though you've saved the file (and folder) to your desktop mapped drive.
