Good to know. But do you know how do I resurrect them from the ether of my reassignment? I moved them to my own "Reassigned" class at some point while organizing my drawing.

Well I moved the none class to reassigned also. I made my own none class afterwards.

My issue is that while learning the software, these automatic classes got in the way and so I reassigned them to a new class called 'reassigned.' Now I do not know what they are anymore, but I cannot delete the class 'reassigned.' And something seems to be disabling my ability to use normal toolset objects (like the property line) which I want to use. Probably because I already tried unsuccessfully to use the toolset and auto-generated component of a plug-in which I cannot see and therefore is not serving me, cannot be deleted. How can I remove the unknown objects generated by plug-ins and start from scratch without removing all of the lines already in my drawing?
