Civil3D - PressurePipeNetwork.GetPipesFittings returns null

Hi everyone,

A similar post about my issue was posted a while ago: Civil 3D Pressure Pipe Network Nodes Problem!
But it was never resolved.

I am trying to extract the geometries of pressure pipe networks (centerlines), and I’m getting the following scaling error:

What is strange is that, it works on the first network, but not on the rest of them. I have tried with other files as well with pressure networks, the scaling error always comes up, sometimes I’m getting a result out of the node, and sometimes a null.

So I tried with this particular one to change the geometry scaling, but it resulted in the following error:

Please find here as well the Civil3D ToolKit log file. I’m not sure how to read that or even use it to find what is causing the issue, so any help would be appreciated.

Thanks in advance!
