Lisp for Retrieving/Modifying Duct Systems Property?

[Dustin11]

 

I'm currently using AutoCAD MEP and I'm looking for a way I can modify (or even find) the Duct Service property using lisp. The only two ways I have tried so far have been by using the vlax-get-property function and looking through the dxf group codes and neither returned what I was looking for. I know its hiding somewhere but I just can't figure out a way to use lisp to retrieve it. I've included a picture with a red box around the property I'm trying to find incase I'm not explaining it very well but sorry in advance if I didn't insert the picture correctly, I can't figure out how to size it larger.

 

Thanks.

AFAIK, many of the Vertical-specific Properties & Methods (i.e. those pertaining to objects specific to Civil3D, MEP, Map etc) were never exposed to Visual LISP ActiveX or AutoLISP; such properties may only be manipulated using .NET.

Ok thats what I was thinking. I was only thinking there may be a way because I was able to pull some other property information such as elevation, material, duct size, etc.... with LISP so I was holding out some hope that there was some way I could pull "System" information as well. Thanks for the conformation though, now I know I don't need to waste any more time looking around in sub directorys and such for something that won't be there.
