Default Re: Circuit Symbol Sizes and Proportions?

Some folk don't like it, but I've found that Express PCB is worth a look. One advantage is that you can make your own symbols for componants to your own design. e.g. - I've a few 555 layouts depending on how I want the chip to look as. I've never tried a valve , but there is a circle/semi/variations tool.
