I haven't drawn "by hand" since around 1988 (?), when I began using OrCAD (for DOS :-)
(I did surprise myself the other day by drafting, by hand/pencil, a drawing and taking it to a machine shop, where they made my part without further question :-)
I presently use PSpice Schematics v15.7
Besides the normal collection of library parts, I have around 1500 customized device symbols, some of which ease calculation of certain simulation values/performance analyses, etc.
Some of these specialized devices are posted on my website.
Additionally, many of these techniques can be easily imported into LTspice. A recent client checked my work using LTspice, directly importing my netlists. He's now switching to OrCAD Capture :-( which I can also directly export schematics to. ...Jim Thompson

Old buck started late. Young buck started in 1986, using Futurenet Dash-2, later Dash-4. I could have gotten on Racal-Redac a year earlier but it ran as a one-seater on a VAX mainframe and only after-midnight slots were still available, so I passed on that. Really young bucks weren't high on the CAD pecking order in them's days.
