Clash Detection Autocad MEP 2009

[Anonymous]

Hi All



I am trying to write an Autolisp Program to automatically add opes to my ductwork and pipwork drawings. However when I examine the Mass Element as a result of executing the clash detection, I get some interesting results. Essentially what I am clash detecting is a wall with some 200x200 duct. However the Interference Dialogue shows as a result of doing the clash detection displayes the information I am looking for namely the Width the Height and the thickness of the wall. Does anybody have any ideas where this information is stored. The width Height and thickness of the wall



any help much appreciated.



Regards
