Where did you find the footprint specifications for the various resistors, capacitors and inductors? Please send the URL's.
those came from one of the libraries at www.pcblibraries.com.
ah, but if you look carefully, for example at CAPC1005M, INDC1005M, and RESC1005M, you'll see that the footprints are slightly different. I think this is because the z-dimension is different on these packages even though they have the same x and y dimension. Of course, I still think things become messy if different vendors or even different series from the same vendor have a different z-dimension.
