In part mode click Analysis>Model Analysis> Model Mass Properties > compute.
Go to : Relations > and write down this sentence : AREA = MP_SURF_AREA () for a surface measure of the model or : WEIGHT = MP_MASS ()
If the system asks you to recalculate the values recalculate them untils the software accepts the relations
Make a drawing of this part and Insert > Note
THE WEIGHT OF THE PART IS &WEIGHT SQUARE UNITS
THE TOTAL SURFACE AREA IS &AREA
Something for the expert users : you can see that the software automatically when we create the relation as I described above creates a parameter AREA (real number) or the parameter WEIGHT. Access the parameters to see it yourself. That is why when we create the parametric notes in the drawing the software finds the parameters &AREA and &WEIGHT.
Very efficient this option, well done quys from PTC
