Why "without any 50 mils offset" Most of schematic symbols are using a 2 logical units (100mils) spacing, which is good. When you have a symbols (like an AND gate) which have 2 inputs, and if you want to put them at location (x, 1 logical unit), and location (x, -1 logical unit), the best choice is grid size = 1 logical unit, and pin spacing is 2 logical units. Most of components are using 2 logical units pin spacing, and the best grid is 1 logical unit. Many gates ( and op amps ) are using 4 logical units pin spacing, and 6 logical units for the pin length, and I am thinking the symbol is too big, at least for gates. grid size < 1 logical unit is useful only to draw body outlines and place texts (fields like ref, value...) Please, think in logical units, not in mils. -- Jean-Pierre CHARRAS _______________________________________________ Mailing list: https://launchpad.net/~kicad-developers Post to : [email protected] Unsubscribe : https://launchpad.net/~kicad-developers More help : https://help.launchpad.net/ListHelp
