iproperty from pipe run OPL can't be found?

[acanfield]

Hello

I've been looking at this :

http://underthehood-autodesk.typepad.com/blog/categories/

which suggest mapping the hidden iproperty OPL created by a pipe run within routed systems

I dodn't know how to find the 'hidden' iproperty or which file it may be hiding in. (.iam, .ipt?).

Any pointers welcome.

I've tried seaching using ilogic (without success!):

Cheers
