Our 'all school boundaries' file can be dissolved into Elem, Mid, and High boundaries on the boundary number (elem_num) and/or boundary name (elem_name)
Using the ArcGIS Dissolver, I can dissolve with the 'create multi-part features' option, and I can accurately create the grade-level boundaries - even those with multiple parts that are then treated as one feature.
But with the FME dissolver, it actually breaks up features that were originally multi-part, and creates two features from them, and I can't create multi-part features.
I've tried dissolving by 1 field (elem_num), and 2 fields (elem_num, elem_name), and I get the same result - two features created from an original multi-part feature, and no multi-part features created.
I've also tried the aggregator, but I keep getting errors about intersecting edges, which I cannot find - but maybe that is the correct transformer to use?
Thank you!
