Header hole sizes

[david_c_partridge]

The 0.1" Headers in Multisim/Ultiboard  (e.g. HDRnXm) seem to use an unusual hole size for all pins except pin 1.

Pin 1 uses a 39.17 mil hole which is OK for headers with 25 mil (.635mm) square pins (35.36 mil diagonal).

However the remaining holes are all 35 mils which will give somewhat of an interference fit :-(.

Is this intentional?   Is it an error?

Is there a quick way to change them all without copying them all to the user database and editing every footprint?

The headers in the "Connectors/SIL's & Headers" section all seem to use 35 mil holes for ALL pins 😞

BTW the English pedant in me insists that should be "SILs & Headers" - the apostrophe is incorrect.

Thanks
Dave

Do an in place edit on the part.

Disable all filters, enable through hole pad filter, select all pins on the component through a drag/select to highlight the pins, right click OVER any selected pin, properties, type the diameter needed, ok/apply, close small X, pins should be the right size
