Multicurve to Multiline Geometry Conversion

Hi @vojvod, in the FME geometry model classification, MultiCurve is a collection of Curve geometries, and Line is a kind of Curve. See here to learn more: FME Geometry Model

I'm not sure what "multiline" in the context means, but the ArcStroker might help you if you want to transform Arc(s) within a MultiCurve to Line(s).

I had a similiar problem when writing to PostGis. I have a shape-layer which will be recognized as Multilinestring when read by QGIS. In FME it appears as FMEMultiCurve. FMEMultiCurve cannot be written to PostGIS Multilinestring - even when there are only lines in it.

Here is my solution:

First use Deaggregator, then Geometryfilter to be sure there are only lines, then reaggregate with Aggregator.

Same problem ...

for me worked:

• GeometryFilter to select only the lines
• Aggregator
• Deaggregator

Then I got in postgis:

• LineString
• MultiLineString

and all geometries were fine.
