The most intuitive drafting program I used is called Draft Choice for Windows by Trius. It is fairly primitive, but very easy to use and old shareware (now discontinued). But you can still find copies on the net:
ftp://ftp.externet.hu/pub/mirror/sac/graph/dcwin2i.zip

It has all you need for simple mechanical drawings, but you can build symbol libraries to do things like schematics. I have one of these I use a lot.

Mine didn't expire, it just scolded me for not paying for it, after 30 days. After several years, I decided I had done enough productive work with it to pay the $60 or whatever to get rid of the nag. Then they dropped support for it.
