Hi,

 

>> i need section properties of the region

Not sure if my guessing is correct now. ;(

 

"the region" is irritating here as "region" is a name of an AutoCAD object type and you have send a drawing with 2 blue regions, if you want to have the mass-properties of the outer region MINUS the inner region you have first to run command _SUBTRACT (to make the inner region an island for the outer one) and then you can run _MASSPROP to get that value.

 

When you start _MASSPROP and select multiple regions you always get the summed value, AutoCAD does not subtract anything as long as that are separate objects.
