CIVIL 3D 2006 - Pipe Networks

[hunterhyde]

I have been working with Pipe Networks in Civil 3D, creating them, editing them, etc., w/o any problems.
For some reason, when I go to 'create a new network' by layout today, the drop down wont let me select 'draw pipes and structures', or the other options....any thoughts on why this is?

Do I need to re-install a service pack or something?

many thanks,

Empty parts list?

Thanks for your response, but I do have parts in my pipe and structure lists.
