  • I do not know haw to get the surface area for a shape

    It's an element property.  This expression gets that property: this.GetElement().Area, where this means the Item Type instance and this.GetElement() retrieves the DGN element that owns the instance.

    MasterPlanner uses the above as part of an expression to calculate the number of buildings per plot.  Here's an example DGN file that contains an Item Type named MasterPlanner. The definition of property Building Count contains the expression ...

    MasterPlanner 01.dgn

    ... no popup box appears...

    Now I'm confused.  Your first screenshot shows a modal dialog.
