Yet further proof that anything worth thinking about has probably already been done to death somewhere!
... Still, I am a great believer in re-inventing wheels - if we had not done that many times over, we would still all be rolling down the highway on slices of log!
If you have Visio, I made a set of stencils for electronics work, including tubes!

It has some quirks I'm still shaking out, just to warn you. :guinness:
I usually just trace everything out by hand; I only trust my computer to play games! Of course, the bigger the circuit, the bigger the migraine! That's another reason point to point rocks! :razz:
I have the full ancient DOS version of Orcad; but lately, I've been using the free "Lite" windows version since it's easier to use and most of the circuits I've been drawing only have a few components.
Must say I appreciate the Bob Pease style of circuit-drawing.
Imho it often makes a schematic more enjoyable to digest (if he has had a good steady hand that day). Adding circuit-updates is another thing...
W.r.t. Orcad-"lite": I went to the orcad-site, is it the OrCAD 10.0 Demo Software you're using ? No 30-days limit etc ?
Michael - I built up all the symbols using the drawing toolbar, although 4001/4030 gates are a challenge. I'm very used to it now, and I can copy/paste various patterns from other circuits I've drawn so it becomes fairly quick. It also prints out in superb quality from excel.
