Similarly, you can get the area of a face using
(get_vol_prop :for_face myface :area)
To specify a tolerance, you just need to add a couple of parameters (in this case using a 5 percent tolerance):
(get_vol_prop :for_part mypart :tol :percent_tol 5 :area)
As you noted above, you'll need to wrap those calls in (sd-call-cmds ...
I hope this helps!
