The CAPR-508P-381W-1016L-1168H__Kemet_C340.fp referenced on the page in the above mentioned URL, is a "Ceramic Conformally Coated • Radial • (Golden Max) Catalog F3101" capacitor (according to Kemet) with a rectangular shape (rounded corners) in the XZ-view and an oblong shape in the XY-view. Note the word "Radial". It's the XZ-view which we do not use in pcb footprints/landpatterns that causes IPC and friends some confusion, as the IPC interpretation (of max. four words) is not enlightened with pictures (saying more than a thousand words).

I think stretching is not possible, but you can use PCB in "footprint mode" to modify footprints. There is a description available somewhere. Or create a new one, there are some tools available to support this. Have you looked at http://www.luciani.org/geda/pcb/pcb-footprint-list.html http://www.gedasymbols.org/ If you can not find it, you may post the dimensions, I will post the footprint...

gEDA-user: stretching components
Hi I used PCB for the first time today, and I needed to alter the distance between pins on a 2 pin through hole device, a large capacitor. I found in the gEDA section of the component lib that the largest was 1", 1000 mil. Is there aa simple way of dragging the pins a bit further apart, or does it need to be created as a new component. Up to now I've been using cadsoft eagle , but I restricted to 3" x 4" boards, but now I have an application that needs something about 3 times bigger, hence the use of gEDA and PCB. Also gerber files are they always in Imperial measures, I was a bit suprised to use mm for holes and spacing, and then see the gerbers in inches. Sorry there's going to be a few, what you may consider daft, questions from me. TIA -- Best wishes Richard Bown # Registered Linux User 36561 OS: Ubuntu 8.10, Intrepid, on AMD Dual Athlon 64 +4400: 8 GB RAM DDR2 Ham Call: G8JVM , QRA IO82SP, Interests Microwave ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
