Creo config option that governs weak to strong dimensions...rounding my numbers to whole numbers

Hi all,

I have creo 2 in work, and im encountering a strange phemomenon in sketcher mode.

I may have edited some modifer that controls this whne playing aorund but cannot find it again.

if i am sketching on a part and am for example using references in an assembly, then i sketch geometry over those assy references....then i remove the assy references and dimension that geometry inside tthe part..using part references....sometimes i might end up with a dimension going to a couple of decimal places....say a hole that i have sketched over an assembly hole using assembly references...is 200.456 from my part edge. I have found now, with that whateverever way my config file is setup...if i right click and strengthen the weak dimension that appears from my part reference i have added when i remove the assy reference....the dimension is rounded to a whole number and the geometry moves tot this. This never used to happen. Can someone point me to the creo configuration option that governs this?

Thanks

Adam
