The lines may cross themselves and the ends of the different parts may not be a common point.

Multiple lines that don't have a common end node cannot be combined anyway. Could you please elaborate the requirement? It would help us to understand your requirement correctly if you could post an image that illustrates the original line and your desired result.
I work in pipelines and the systems are subdivided into multiple levels all the way down to the individual pipe segments. I want to aggregate (or Dissolve in ArcGIS terms) one level of the pipeline (Series) up to the next level of the pipeline (Line)--I used the FME transformer Aggregator and it did this, but it gave me multipart features and I need single part features. See the two related pictures that I have included--the first one called "Dissolved to LineLoop" is the result of the aggregator and it would be correct if each line in that table were a single part feature. However, many are multipart features, which you can see in the second picture called "Diss to LL exploded" where I use ArcGIS to explode the multipart features into separate features. Each Series that I am aggregating touches other Series in the Line that I am aggregating to, resulting in continuous lines, however, the Series may not touch each other exactly at their end points--see the last picture called "ShouldAggregateToBeSinglePartFeature" for an example of this.
Hi,
Did you find a solution for your problem? I have the same problem.
I am starting from polygons that I want to convert into lines (Topolgogy Builder) and then clip the lines with a polygon (Clipper). In the end, I have clipped Line-Features and some of them are Multipart-Features. I would like to have them only in Singepart-Features (comparable to Multipart in Singlepart in ArcGIS).
Another idea would be to use ArcGIS-Tools in FME... Is this possible? I only know that it is possible to use FME tools in ArcGIS with Data Interoperability... But the other way round?
@pelle123 I'm not quite sure I follow your question, but if you want to convert a multi-part polygon (or line) to a single part-polygon or line then Deaggregator should do the trick. In FME we think of a muiti-part geometry as an aggregate.
@Mark Stoakes. I found out, that the multipart-Features were created in the step behind that using the clipper. Thank you, with the Deaggregator it works now. :)
