I know the word, just not what it means in this case… Getting Started with PCB has a list of terms. I have a copy online here: http://www.delorie.com/pcb/docs/gs/gs.html#Terminology footprint A footprint is the pattern on a circuit board to which your parts are attached. This includes all copper, silk, solder mask, and paste information. In other EDA programs, this may be referred to as a “land pattern”. “Footprint” sometimes is used to refer to a footprint file. “Footprint” refers to the pattern; “element” refers to the instance. For example, your layout might have four elements that use one footprint. ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

Do that and then save the symbol with File→Save Page” My problem is that there is no ”Save Page” in the File menu. File-Save But first it is important to recognize that there is a difference between editing a symbol, and editing a schematic with a symbal instance and instance attributes. Until now we were talking about editing a symbol instance in a schematic. To make a new symbol version, you must open the symbol file itself. You can do that by selcting the symbol in a schematic and do Hierachy-Down Symbol (Shift-H s) You will discover, that the symbol still has no value attibute. You can add it in the symbol file. The value attribute must be promoted when the symbol is instantiated. There are (not so?) complex rules which attibutes get promoted, and which not. I think, a visible, unattached attribute, called _value_ will be promoted. N.B., this is a dark side of gschem in my oppinion. Which attibutes get promoted should be defined in the symbols, independently of visibility or any strange configuration settings. After adding the attibute, value=? with proper placement and alignment, you can do File-Save_As to save the new symbol in your own symbol collection. Edit-Symbol_Translate will probably not be required, if you just do a minor modification to an existing symbol. Then you go back to your schematic, Hierachy-Up (Shift-H u) and delete the old symbol instance, and replace it with an instance of your own. How to reload the available symbols from a running gschem? I don't know. Usually I restart gschem, to reread the available symbols. You'll first need to add the location of your own symbol collection to the search path in .gafrc or something. -- Stephan ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

It should have the diamond on the right position. 11) regenerate the information of the footprint that got lost during the process: a) pin and pad numbers -- [n] on pins and pads b) square flag -- [q] on pins and pads c) proper solder mask clearance -- draw a rectangle in copper over the footprint -- activate solder mask -- go over every pad/pin and type [ctrl-k] twice. This will decrement the size of the hole in the solder mask -- deactivate the solder mask d) position of the text associated with the footprint -- [n] somewhere inside the footprint where no pins or pads are -- type an arbitrary string in the dialog -- click ok -- move the string to the desired posion 12) select the footprint (click on footprint) 13) cut the footprint to buffer ([ctrl-x]). It doesn't matter where you put the mouse cursor at this step. 14) from the buffer menu: save_buffer to_file Yes, this is tedious.

By virtually nobody I am sure he means an extremely small number, and if you are referring to just yourself (rather than a team, perhaps), then his statement is still accurate.There are more of us that would appreciate such defaults than those who would not. Resistors are just one of many component types out there have a value, no matter what type of package they come in - with rare exceptions, every single one of them you pick up will have numbers or color bands indicating that value, we all know that. That value might be zero ohms, but it is still a *value*. The same goes for every last capacitor, inductor, etc., though I think you'd be hard-pressed to find any that have a value of zero. Anyway, I suggest the following: * If the part in question can usually be described by a single value, for the purposes of the signal flow in the schematic that is, then give it a default of value=0. * If it is a discrete part that is specified entirely by its part number rather than a measurement, like a diode or a transistor, then pick a reasonable default; value=1N914 or value=2N. * If the part is something like a logic IC, use the standard name of the part in the fastest commonly available series for that particular gate; value=74F74 or value=74HCT245. * If none of these fits, then leave the value= attribute off entirely, since the user would have no choice but to get creative anyway. The point here is that every one of the component types in question has a value, therefore the value= field will end up being utilized by nearly everyone who instantiates the symbol for that component. Otherwise, schematics with a lot of such symbols become nearly impossible to read, let alone debug. -- There are some things in life worth obsessing over.
