Inch External Lock Washer

So I went looking for an Inch size External Tooth Lock Washerin my toolbox and there isn't one but there is a Metric one. Icontacted my VAR about it a while back and they didn't have oneeither so I'm assuming it's an oversight.

Today I monkeyed around with the Access files and saved a new Inchone from the Metric one but I've got a problem...the part did notactually update when I changed the units from MMGS to IPS. Whenadding the washer to an assembly; the Property Manager for thewasher shows it having the correct values for the part but when Ihit the check button the part suddenly takes those inch values andconverts them incorrectly to millimeters (divides them by 25.4instead of multiplying). So my #4 washer turns out to have a 0.005"inside diameter instead of 0.123".

Has anyone done this same procedure and had it work correctly? I'veattached 2 images of the pre and post "check" of adding the washerto an assembly.SolidworksToolbox
