Do they have symbols?
"Virtual" footprint means the physical "component" is made only by the drawings on the board. Therefore: - These fp have (usually) no 3D shapes, and the component should be not in BOM. - They of course have a symbol in schematic. In fact any footprint connected to a at least one net *should* have its corresponding symbol in schematic. (I am thinking all footprints should have a corresponding symbol because in many cases these fp need a unique refdes: for instance to import them to a .dsn file) Microwave elements, and edge connector cards are often virtual, if only a drawing is enough to create them. Net ties are virtual and *need* a symbol. However, Microwave elements and Net ties connecting 2 or more different nets are not easy to use in Pcbnew: See this thread https://lists.launchpad.net/kicad-developers/msg24455.html to know what is missing in Pcbnew (the Tomasz's proposal is exactly what is needed in Eeschema/Pcbnew). Mechanical holes can be virtual or not: A mechanical hole with a screw inserted inside it should be not virtual. -- Jean-Pierre CHARRAS _______________________________________________ Mailing list: https://launchpad.net/~kicad-developers Post to : kicad-developers@lists.launchpad.net Unsubscribe : https://launchpad.net/~kicad-developers More help : https://help.launchpad.net/ListHelp
