Eagle - Caps with multiple lead spacing?

[Botch]

The rain hasn't let up today so decided to design a power supply based on a LM317 with HEXFRED or Schottky diodes but no transformer on board. Simple little guy but as I've got several things planned that all need power it may actually be made. This is the first time I've used eagle (or actually done any layout work for 10+ years) but has been fun.

I'm just looking at the Millet Hybrid board and it has used multiple lead spacings on the capacitors. i.e. 5mm, 7.5mm & 10mm for one cap.

How can I do this in Eagle? Do I need another library as I can not seen to find it in the standard ones?

Cheers,

Botch...

Someone may have a better answer, but the way I have done it is to insert additional wirepads of the appropriate size into the schematic, connect them in parallel with the cap, and place them where you want on the board. YMMV.

I dont know about Eagle, but some tools let you insert vias to power and ground planes. It is sometimes more difficult and potentially more messy to make multipin symbols and pcb part geometries. For example, on the Dynalo Rev C baords I did in Mentor Expedition, an extra via to ground was put in "inside" the cap footprints in order to give the smaller leadspacing. The tool may complain that this is a design rule violation, but you might be able to ignore it. If you are not using a ground fill, this approach may not work for you.

there should be some in the rcl library, though there are only few. You can design your own devices, but afaik the component/library editor is only included in the full versions of Eagle.

Thanks for the replies. I should have been clearer that I wanted it for some big electrolytic caps in the power supply.

I've used Pars method of adding some extra wirepads and that looks ok.

I've just downloaded the demo version of eagle today so designing device is a few days away
