Jamal - Use the Deaggregator transformer.
Thank you Sami for the answer,
If the square is exploded in the AutoCAD then 4 lines are generated.


Applying the deaggregator to the same square fails to introduce 4 lines.

What might be the issue here?
Then try using Deaggregator, GeometryCoercer and then a Chopper..
The trick here is to determine the chopper's settings for the interval to explode (Split) for your case..
Mode: By Vertex
Maximum Verticies :3
The workbench below fails to explode the square and then to generate 4 lines.

What I wanted is a tool that can explode objects at each vertex which is the default behavior in the “explode” tool of AutoCAD.
Is this still possible in the FME?
yes it should be..
ok sorry try setting the (Maximum Verticies :2 ) for the chopper..
Perfect Sami. It works fine now.
Then what is the advantage of the “deaggregator” in this case?
none and also the GeometryCoercer serve no purpose in this case.
Thanks ETLS. This is what I guess. Then Chopper is the equivalent tool for Explode
Best
