During my customer visits I've more and more found out that, in the country where I live, companies are relying mainly on "cordinate" dimensioning and just plus/minus tolerancing.
If you dimension a part with DimXpert by using plus/minus tolerances and show tolerance status it will show the part as undefined.
Take the example of this shaft: these are used datums:
And this is the tolerance status when using Plus/Minus dimensioning scheme:
Cylindrical surfaces are undefined.
This is not a fault in the software, it is correct, because there no tolerances to define form, location, and orientation of the surfaces.
When using GD&T dimensioning scheme the shaft is completely defined:
When a designer uses DimXpert the software will take care of all the hard work of completely defining the part and check consistency of dimensioning respect to GD&T rules.
This will ease desginers' life.
A more detailed explanation of why GD&T is better than coordinate dimensioning is here:
So we should push more the importance of using GD&T.
