What is your intended use case? What version are you on? is this intended to serve data to the web?
When we implemented WDM at 10.2.1a, we made some significant changes on how our objects are constructed. Running a trace outside ArcMap or ArcFM Viewer For Engine is going to be challenging at best. However, depending on your use case, we have REST endpoints that you can hit to get most of that data without using ArcMap.
I will be more than happy to help you with the details.
We are trying to generate a KML trace for fiber/port, this KML is imported by an asset management system.
Yes we are planning on a Web Service and I was just experimenting with the developer sample.
We are currently on 10.2 and we do have a ArcFM Server available with us. Will really appreciate if you could point us in the right direction, thanks.
