[vegaz]

I use OG occasionally to draw some relatively simple electronic circuits. It works acceptably, both with the Mac and the iPad version (for the last one you can simply download the appropriate stencils from graffletopia).
In your usage scenario, however, I see a potential problem which I have not been able to solve up to now: if you have to draw a switch with 24 ports on it, you need 24 magnets to have the connectors correctly positioned, and I do not know if it is possible. Just two or three days ago I designed the basic shape of a 16-pin IC, but I could not find a way to create a magnet for each pin.
I hope someone else will chime in here, because my last circuit is still waiting to be drawn in OG... :-(

UPDATE: a bit of forum searching seems to show that manual adding of magnets should be possible using the magnet tool. I'll try that out as soon as I can, and let you know
