You're allowed to create subcategories for Matchlines, however you can't really assign a Matchline to the Sub category.
Many buildings require both 1/4" and 1/8" and sometimes 1/16" Matchlines.
I know were all perfect at putting things on Separate worksets and never make mistakes so they are a workaround.
But sometimes newer users tend to forget to look at what workset they are working on. So turning off worksets isn't always a great idea.
Wouldn't it be nice if you could add a sub category and just turn off that sub category in the view template?
Seems like the functionality is already there. We just need to be able to assign it. Not much different than assigning linestyles to boundary lines of a sketch when creating filled regions.
