Hello everyone,
I need help with polygons and multipolygons with my geometry, i read shape file if that is important
1. Which transformer should i use, or how can i see if my geometry is polygon or multipolyon ?
2. How can i change type from polygon to multipolygon, what should i use for that change?

Hi
You can use AggregateFilter or GeometryFilter to determine if the geometry is Area or MultiArea, and use Aggregator to change Area to MultiArea.
Hi
Can you please tell me what parameters should i use in aggregator
I connect geometry filter first, and i get Area, so what should i do next?
Thank you in advanced
Check Group Processing, then
- Group By : <select unique ID attribute>
- Complete Groups : When Group Changes (Advanced)
If the input features don't have unique ID attribute, consider add sequential number attribute as temporary ID by inserting Counter before Aggregator.
Note: If you use GeometryFilter to separate Area and MultiArea, set "Detail" to the Mode parameter and "IFMEArea" the Output Port parameter.
