Hello,
I have polygons that are constructed from lines using line closer and area builder so i could add some attributes from other features. Now i need to deconstuct back to lines with those attributes. Unfortunately i had no luck searching the forum for related issues. Any help?

Maybe use a GeometryExtractor first to store Geometry into Attribute. Then select Generate List within the LineBuilder. And then after all the Transforming use the ListExploder to go back to the individual Features and restore the Geometry with the GeometryReplacer?
+19Hi @luckym, if you set 'Yes' to the Preserve Lines as Path Segments parameter in the AreaBuilder, you can restore the original lines with applying the GeometryCoercer (Geometry Type: fme_line) and the PathSplitter after adding some attributes to the area.
Optionally, you can also restore attributes of the original lines, if you preserve them using the Generate List option in the AreaBuilder and then set the list to the List Attribute parameter in the PathSplitter.
