Also - see the link in my signature. Several good threads on that type of thing in it

I read these posts already, and a lot of the lines types shown do not indicate what exactly the lines are for. I was reading somewhere in one of these forums that lines should be named but what they are like Cut line or Match Line not 5-solid-black or 8-hidden-black, etc. This way it is easy to select a line and you dont have to think which line type to use. I know that these decisions are up to me, but I just want a sampling of what the industry is doing

I'd generally agree with that - makes it easier if at any future date your line settings have changed and you want to copy or reuse some family. Also it helps in the 2nd portion of the project setup - see below.

As for the line types and widths, it's generally up to you. Though there are some standards you could adopt like AIA. Generally I start from one of these then tweak it so it looks more proper when printed. That tweaking is quite important as it removes the "blank" look you generally get with Revit drawings.

Simply choosing line types / widths is only half the job. The more important (and time consuming) portion is to assign types and widths to the various object styles. That is where the trick to getting your drawings to look correct lies.
