Drawing schematics on a computer?

[Terry]

The symbols too, will be really useful, but I'm note sure how to import them into a Paint drawing. If I click on 'copy' (a symbol), I can click on paste in MS Word, and there it is on the screen. Same with 'Publisher'  but If I've got Paint open, (a new drawing say), and copy a symbol then click on 'paste' nothing happens.

What's the process of importing symbols into Paint please?

I'm not sure I understand this, David.

I just open my symbol sheet in Paint, then open another instance of Paint for the new drawing. Then I just select the symbol(s) I want and copy and paste to the new drawing.

Incidentally, I use + C and + V for copy and paste - it's much quicker.
