Export Options, within the 3D Print Hub are not selectable. I want to set the export option to selected, but am unable. When I Send to Preform all of my subtools are being sent, which is not what I am trying to do. Is this a bug in ZB-2019?
Weird. It works for me. Is your target tool active and in edit mode?
If so, I’d suspect an issue with your installation. Maybe try downloading a fresh installer (they can become corrupted), and follow the installation instructions, especially in regard to disabling Antivirus, which can interfere with the proper installation of some components.
