Leave VW Classes and Layers as they are
When training people to use VW there are many more complex perspectives or VW ways of doing things than understanding Classes and Layers
When you try to show Worksheet formulas or even Saved Views and the reason for using the latter - is it really a workflow and understand of the software a new user needs to get their head around
So ... who cares if a new user was using AutoCAD, Revit, or whatever
Hey - you are using Vectorworks now - get your head around it!!
