I've been able to add a pipe to MEP through vb.net. I found out how to place the pipe on the correct system and use the correct style among other things. Unfortunately I can not find out how to apply the Routing Preference I need. What's even worse is that it doesn't apply ANY Routing Preference which causes the Pipe Curve object snap to NOT work on the pipe.
Searching the object browser within the editor reveals numerous entries for routing (PipePartRoutingPreferencesStyle), but I can not see how they are linked back to the pipe.
Is there any other documentation on how to added MEP objects to a drawing besides the little that is included with the samples folder.
Any thoughts or directions would be appreciated!
It is almost useless to ask a MEP .Net question on these forums because they almost never get answered. But to answer your question, I know autodesk university has some good information on programming MEP with .net. I believe it is free to signup but not for sure because I am on subscription. I know that it is free with that.
