I have been using AutoCad since 1983 and GstarCad since 2009.   Both have the ability to save Layer Property *Sets* so that you can turn on a set of layers say for mechanical and save that set and have another set for Electrical etc and you can switch between these sets quickly.   Is there a way to do something similar in DraftSight?  If not how do you work around this.  I just may just be lazy and used this tool because it was available to me..
