Issue
When attempting to use the pipes in the ANZ country kit you may find that all of the Pipes and Structures you are expecting to see are not available for use.
Cause
The Pipe Network Catalog has not been set.
Solution
To fix this go to the Home tab of the ribbon, the Create Design dropdown, and select "Set Pipe Network Catalog"
In the dialogue box that comes up set the two dropdowns to ANZ Metric Pipe Catalog and ANZ Metric Structure Catalog respectively.
Then you should find that all the parts are then available. (A restart of Civil 3D may be required)
