---- SNIP ----

But I do use them (0.5mm lead pitch) in combination with imperial
dimensioned components. Package information on datasheets are
indicating more and more: *controling dimension: millimeter*.
Metric components will become more common in the near future.
That is why I think that Protel should switch smoothly between
metric and imperial without rounding errors.

just my 2 eurocents.
