- Is it possible round off area values (database_length/database_area) to two or three decimal places in GSA?

If  any database graphical source like Oracle Spatial or SQLServer Spatial is used in GSA/Bentley Map then you see a property named database_* for e.g. database_Area , these value is calculated on the database side.

It will then be in whatever coordinate system the data is stored in the database. The other calculated properties like geometry_area, geometry_perimeter and geometry_length are calculated by XFM on the client side and are in the dgn units
