A topic that seems to make the rounds via support or in training classes is to add sizes to the out-of-box pressure pipe catalogs. Due to the fact that these are formatted as SQLITE files, you can imagine that a simple text editor will not do the trick. Luckily, this is still a pretty straightforward process but with certain caveats.
Let's take for instance, the Imperial_AWWA_HDPE catalog that comes installed with Civil 3D. With the single material included in the catalog, you are offered a select set of pipe sizes, ranging from 1/2" to 3".
This seems to be more of a starting point rather than serve to be a comprehensive list, and for smaller applications only. However, if we were to make available, a catalog that follows the DR7, DR9, or other specifications, we would need to know the best route for doing so. This is where the Content Catalog Editor (CCE) comes in (for those that were not already aware of this).
In this application, launched outside of Civil 3D, adding pipe sizes involves just a few simple steps. However, each size must be entered one at a time. In the included HDPE catalog, there is a 'Pipe' classification in the left pane (1) that expands showing two part families, named by specs. Highlighting a part family exposes the available list of pipe sizes, complete with defining parameters, on the upper right pane (2). Further, highlighting a size in the upper right, shows the construction of that particular size in the lower right pane (3). This includes each end (port) of the pipe and the parameters defining each.
Adding a part size involves using the Import Part icon or right-click option
Initial options involve choosing to use a .CONTENT file or not (pipes do not use these), then define the industry (water only), part type (pipe), and part family name. This can be an existing one listed or defined as a new one by simply typing in the line and clicking Next. The following page allows you to enter as many parameters as you see necessary, and the define each end on the last page. Voila! You have a new part size.
You can further edit the size(s) or add parameters as needed. Make sure you save your catalog before leaving!
Now, back in Civil 3D...
If you have a Parts List that was created before the addition of your new part sizes, this is the time to frown. You will not see the new sizes when you go to add them. Instead, you will need to create a new Parts List (trust me, I know that part is a pain). This is because the definitions it reads is a one-time import/read into Civil 3D. Once you create the new parts list, it will reread the catalog file and its contents. you will then have access to your new pipe sizes.
