: Thank you, Jeff, for your help.
: I check the page setup. It's in inches. I click on C cell under
: format column, change to mm. However, when I go back to double check,
: it's in inches again. Am I missing something?
"...it's in inches again"? The drawing dimensions? The export/import to AutoCAD?
Anyway, this discussion is a little confusing. I know when people get stuck,
try a bunch of things. And, in this case, there are several things which seem to
apply to 'units': the units setting in 'Edit>Setup>Units'; a .dtl option called
'drawing_units'; and the radio button selection of inch/metric when setting up a
drawing or format. Only the setup of units in the part is absolute ~ it applies
everywhere: drawings, formats, exports.
The 'drawing_units' option in the .dtl file is a little confusing. It is one of
those misnamed, misleading Pro/e options, leading me (at one time, anyway) to
believe that you could specify dimensioning units with it. Not so, as it nicely
lets users 'speak' in any system of units to the .dtl file. It tells the drawing
setup file how it should interpret measurements, such as, of arrows, leaders,
dimension text height, section note height, etc. So, dimension text with a value
of "3" will be interpreted as 3mm if drawing units are set to milimeters. If,
however, drawing_units is set to inches, you better have a value like .125 or
for that same text.
On the last point, of the significance of setting millimeters or inches for the
drawing, I'm pretty sure that all this does it tell you, in one system or
what the size of the sheet is. You can pick a US Customary size like A or B but
get it tranlated into mms. Likewise, pick A4 and click the Inches radio button
get this standard ISO sheet size translated into inches. This should not have
effect on drawing dimensions (though it would be nice if were some kind of
automatic units conversion) or of the units that get transmitted through an
This leads me to believe that the problem is in your AutoCAD setup, perhaps some
built in scaling factor. Check your .drw scale factor (sorry, can't telll you
where to find it.)
