I create a different schematic symbol for each value of component and size. For example, 10K_1%_0402. It's always been faster to create more values by editing the lib file with cut/paste in a text editor.
I have run into problems under the latest version of Kicad. For starters, the latest version installs under Program files/KiCad/share/library. Vista unfortunately does not want mere users to mess with files under Program files, so I have to run my text editor as an Administrator. The big problem I am running into is that edits using the text editor no longer seem to make any change to the part Kicad is using. I first text edited my resistor library to create a new thermistor. It showed up in the Library editor where I added to the graphics. However, the graphic changes do not appear in subsequent text edits. And changes in the text editor do not appear in the Library editor. Is KiCad caching this somewhere? Is there some way to synch these up? Previous versions did not do this. In case it matters, I always close one program before starting the other (Kicad, text editor). Regards, Doug
