Schematic drawing program

kicad open source LTspice

If you don't want to mess with schematic capture as such then give Dia a try. It's a FOSS "Visio-like" app that works well for diagramming, flowcharts, and such. It originated in the Linux world but there is an installer for, and it works pretty well on, Windows. See here

for Windows and over at for the main project page.

take a lot at "TinyCad" on the net..

Oops. I meant Take look at TinyCad..

Must of had too much to drink last night :)

On a sunny day (Fri, 25 Dec 2009 08:55:59 -0500) it happened Rich Webb wrote in :

circuit

In the old days I used 'xcircuit' in Linux. It creates postscript files (.ps), and has a lot of ready made symbols. Here a screenshot: ftp://panteltje.com/pub/xcircuit.gif Here the postscript file of that diagram it created: ftp://panteltje.com/pub/xc.ps

2nd Tiny Cad, has potential.

Cheers

:-) Merry Christmas! I already have a copy of TinyCAD that I downloaded quite some time ago, but never really tried out seriously. I installed it just now and had a quick look. The "Export as image file" feature seems to be just what I wanted. I also like the default white background unlike many CAD programs that use a black one.

I haven't tried creating a user library of symbols. If that's as easy as I hope it will be, then this could be just what I wanted. Thanks.

TinyCad comes with quite a library of symbols straight out of the box.

CorelDraw does not have a library, but you can create the equivalent by making a template.

I already have KiCad and LTspice, but AFAIK they can't save in standard image formats.

Ah, but CorelDraw isn't free.

circuit

Ahh! Thanks for that. I've used xcircuit in the past but had completely forgotten about it. Must be getting old(er).

Looks like you might have your solution already, but ExpressPCB

also has a cad program that's dedicated to schematics. You can use it for drawing only (ie, with no intention to capture the schematic and/or actually make a circuit board.) Very easy to use. Cost =3D free.

My Gonzo utilities, of course.

(3) is not even wrong. The ONLY format you should consider for a schematic is .pdf.

Postscript is just as good, .ps files are also vector based, and can be can be printed directly by most printers.

Set up a Postscript printer driver to print to file, print using this from LTSpice, then use Ghostscript (free) to convert the resulting Postscript file to pretty much any image format you want.

Yes, and it is absolute crap. It's line drawing is counter intuitive and its library severely limited. Like the rest of the program it is basically rubbish.

Late at night, by candle light, "pimpom" penned this immortal opus:

Try KiCAD. Schematic capture and PCB with extensive bundled library you can add your own to. Dunno about graphic capture.
