Flitch , I think you posted this in the wrong thread.
Roseda, Isn't this effect you see not coupled to the old NX definition of three line widths , Thin-Medium-Thick?,
"These three names" are mapped to three physical values , such as the ones you mention. ( see final line)
This old width definition is based upon that the plotters back in time had real pens and the setting of "thin" rather was an instruction for the plotter to select a pen from a pen holder than the width of that pen. ( something like: Thin == slot 4 in pen holder ≙ 0.18 mm)
This also meant that these "Unigraphics fonts" should be able to plot using a pen, the letters cannot be filled or have varying width.
That said, I do not think that the old "Unigraphics fonts" has a width defined, it's rather the "width attribute" to select the correct pen. Thin - medium -thick.
But, since NX8 (? ) NX can have 12 ( 9+3 ? ) thicknesses defined but probably the "unigraphics fonts" are using the thin medium thick names and...
this is set up in the customer defaults,: Gateway -Line Widths- Conversion : Thin== x.xx etc etc.
