DGN -> extrude -> DGN with solid shading

Dear all,

 

 

My problem:

 

I have a 3D DGN file with roofs.

 

I would like to generate a 3D house model by extruding this roofs by -20m.

 

 

This works pretty well until I export this result to a DGN file.

 

Every building consists now of 2 closed shapes (roof and extruded bottom) and 4 lines connecting these shapes.

 

 

What i would like to have is model with solid walls in the DGN file.

 

 

I assume i have to generate surfaces to give them a "color/texture". 

 

But how do I do this?

 

 

Thanks in advanced for the help!

 

 

Best regards

 

Thomas

Hi Thomas

 

The extruder creates composite surfaces which FME cannot yet write to dgn.  After the Extruder you could use the GeometryCoercer and the Deaggregator transformers to break each wall into a 3D polygon, and then the FeatureColorSetter to apply colour.  You can write these 3D polgyons to dgn which should give you solid walls, although not surfaces.

 

Hope this helps
