Hi I am new to using FME.

 

 

I have imported an IFC file in a reader.  I would like to take the ifcSpace geometry (an Aggregate Solid) and break it down to its constituent faces.

 

 

Any ideas please?

 

 

Thanks

HI Gareth,

 

 

possibly a series of these transformers works.

 

1) Deaggregator to decompose the aggregate solid into individual solids.

 

2) GeometryCoercer to transform the solids into composite surfaces.

 

Geometry Type: fme_composite_surface

 

3) Deaggregator to split the composite surfaces into individual surfaces.

 

Split Composites: Yes

How can you deaggregate a solid into the main surfaces without ending up with all individual faces?

I would like to merge all those coplanar faces. I have tried the SurfaceDissolver but it doesn't work.
