CADPipe, need some info

[Glenn T Jayaputera]

I aint too sure if this is the right group to post this message.
Well, I am looking for a CAD program that specifically for modelling pipes
inter-connection.

Well, the whole problem is this. A 'running' manufacturer would like
to draw the floor plan of the massive inter-connecting pipes. They want
to have a 3D cad diagram, means that they want to know all the X-Y-Z dimensions
of the pipes. They would like to know if for example they zoom a particular
part, how high is the pipe from the ground, etc. More interestingly, they
would like to know (if possible) alternative path if one of the pipes known
to be leak.

I believe simple CAD diagram is not appropriate for this problem. Can
somebody directly any appropriate software to use?? I need a CAD program
that specifically built to model this pipes inter-connection. I heard about
CADpipe, has anybody heard about that?? Where can I get it (or even get some
more info on it).

thanks in advance
Glenn
