Display Area for a Drawing Section in a Drawing Text Box

How do I calculate the area for a section of an extruded profile and display it in a drawing note?  I see how to add a field <AREA> in the text dialog box, but it comes up as N/A in my text box in the drawing.  This is also the case for <MASS> and <VOLUME>.  How do I get the drawing fields associated with the physical properties of the model?

update the mass props of the object. 


I'll bet that the area prop is the surface area of the object, not a cross-sectional area.

You are correct.  I was able to get the field properties to display by going to the model and calculating the physical properties. 

The area is the surface area which I do not want.


I figured out to get what I really want which is lbs/foot of a profile.  I created a sketch on the extrusion and created a reference dimension and renamed it "Length".  I then created a user parameter named LBperFT.  Then I created an iLogic rule and defined LBperFT = iProperties.mass / Length.  In the drawing note I displayed the user parameter LBperFT.


This seems to work.  Is there a better way to do this?  This will not be accurate if I have other features added to my extrusion such as holes and cuts.
