Is it optimal? IMHO, this is a matter of style and taste. Therefore it cannot be decided based on purely rational arguments. There is quite a range of acceptable relative sizes. And there are traditions. Note the plural. :-) > I > can remember that some people complained that symbols are too large > some years ago. Well, I was none of the complainers. In fact, I like the symbol size to text relation in the default library. Note, I am talking about the size of the symbol excluding the pins. The pins seem rather large in the default lib. This makes for unnecessarily awkward positioning if space is tight. > But now I get the feeling that basic symbols (resistor, capacitor, ...) > are indeed too large compared to the default 100 grid size.

But their pins are 100 units rather than 300. So my resistors end up 600 units from hot spot to hot spot. Same with capacitors. > Or, compared to the symbol size, default 100 > grid is too small.

See http://ssalewski.de/PetEd.html.en I prefer the European/Asian style of resistors as defined in DIN EN 60617 This standard uses boxes rather than zig-zag lines. The length of pins in the artwork of a resistor symbol in the standard are 1/6 of the length of the box. This is even shorter than the pins in my library. > Note: On that picture you can see the 9 gray position marker crosses > which are displayed when mouse pointer hovers over a text element.

Usability of PCB could benefit from such visual hints, too. ---<)kaimartin(>--- -- Kai-Martin Knaak tel: +49-511-762-2895 Universität Hannover, Inst. für Quantenoptik fax: +49-511-762-2211 Welfengarten 1, 30167 Hannover http://www.iqo.uni-hannover.de GPG key: http://pgp.mit.edu:11371/pks/lookup?search=Knaak+kmk&op=get
