I would recommend the following:- Have a small symbols library created for this purpose. The symbols are almost copies of existing symbols in (for example) the "device" library. It is likely that this library would be fairly small (pots, switches, transistors, segs or basic displays).
Add a default footprint to the symbol description, e.g. rad0.1 or whatever. Make sure that any pins on the symbol that will not actually be used on the footprint are changed so that they are only graphical images and no longer electrical. Make sure that pin designators match the (desired footprint) pad designators that will be used. I would also rename these symbols slightly. When these symbols are used on the schematic I tend to place a dashed box type enclosure around them. Somewhere I show that this implies the components are mounted to a mechanical assembly. Although this requires initial setup, overall it seems to convey good visual readability, it also gives good electrical connectivity throughout the sch->pcb, that is - no errors. As someone else suggested, the off-board components do need to connect somehow to the pcb. This works for basic projects - would it work for yours? Liane. Hello, can somebody recommend a way to handle components that I want to appear in the schematic, but are not mounted on the PCB (e.g. switches, lamps, fuses ...). I thought of the following ways to do this: a) create a separate schematic sheet with the off-board components, connected to a sheet symbol for the rest of the circuit. b) Draw the off-board components with drawing tools, so that they have no electrical connectivity. Neither approach seems to be entirely satisfactory, because with a) you have to refer to two sheets if you want to understand the circuit, and b) gets cumbersome for anything more complicated than, say, a single resistor. Does anybody here have better ideas ?
