@donneyclark, I agree and second Dave’s comments. The different drawing/drafting standards around the world set a fabulous starting point for developing one’s chosen toolset, based upon discipline, project and locality.
Creating expansion packs (scrapbooks) is a wonderful professional and business opportunity for those so interested in this element of what we do.
For my workflow, line work (still thinking through new SU lines choices), symbols and sheet standards are a part of my LayOut usage.
