Question

Extract ID property of a polyline vertex (from ESRI File Geodatabase feature class)

Hi,

I have a polyline feature class in a File Geodatabase (10.3.1) describing the routes of pipelines. These are 3D polylines. Each vertex contains four properties: the first three describe the X, Y and Z coordinates, and there is a fourth "ID" property that contains an integer value. This "ID" property is never used by the feature class to hold any information regarding the vertex index. It's basically an empty tag. In my case this integer value was used to hold some status information. Now, I wonder if it is possible to access this "ID" property. I have not found a solution in FME Desktop.

In the end I need to extract all vertices in order for each polyline, describing the X Y Z and ID values as field attributes in a table.

The "ID" property was set using ArcObjects. It can also be accessed this way and I believe the ESRI's Geoprocessing framework (python) can read/write it as well. But for my solution and FME workbench would be a better fit.

Hi @bassman Try the MeasureExtractor. That last value is generally used on lines to be the length along the line, but really it could be any value, such as an ID.
