Is there anyone who did this before? Or does anyone >know a workaround? the behavior you are seeing is how Protel is designed to work. Nets are not assigned in symbol and footprint libraries (except for power nets with hidden power pins). So there is no workaround. Instead, use the program the way it was designed. Do *not* save this block as a library. Absolutely, that is not what you want. You have a collection of components there. If you save it in a library, it will become one component. (If that is what you want, i.e., a single component with an array of pads that are later used to load more than one component, you can do that, but usually this would be a bad idea, outside certain special applications.) Instead take your block and save it as a PCB file. Do similar with the schematic of your block. Then, when you are creating a new schematic, you can place (copy and paste) the schematic block and wire it up. The schematic is what assigns nets. Then you load the net list into the PCB (or synchronize the PCB or update it, this process has been called by different names at different times). (You can also assign nets with a net list. If you have your PCB block separated into its own file, and it has nets assigned, you could generate a net list from it. But this is not usually a good idea. It is *much* safer to create the net list from the schematic.) (If it happens that you are designing boards without first creating a schematic, which people do from time to time, change your errant ways! This may seem to save some work, but it does not really save much under the best of conditions, and you will not be using the checking tools and a whole host of facilities that the schematic/pcb combination will give you. I create schematics even for very small boards.) ____________________________________________________________ You are subscribed to the PEDA discussion forum To Post messages: mailto:[email protected] Unsubscribe and Other Options: http://techservinc.com/mailman/listinfo/peda_techservinc.com Browse or Search Old Archives (2001-2004): http://www.mail-archive.com/[email protected] Browse or Search Current Archives (2004-Current): http://www.mail-archive.com/[email protected]
