Hi there guys (and girls),

 

I've been trying to combine several 3D-geometries (arcs, polygons, lines) into 1 big polygon.

 

What I have now are seperate parts (a window, a floor, a wall and so on), but what I actually want is a clean building that is only clickable as a whole.

 

I already managed to combine the different geometries into a geometry collection with the Aggregator Transformer, but I was not able to write this geometry to the destination file (OBJ).

 

Does anyone have any idea how I could solve this problem?

 

I am looking forward to hear from someone else from this planet soon,

Claire

Hi @claireproemeren​,

You could try using a Triangulator to convert your existing 3D surface geometry into Meshes, then using a MeshMerger to group them into a single 3D object for writing to OBJ. Any non-surface geometry (ie. lines, polygons) would need to converted to surfaces first, with the FaceReplacer or Extruder transformers.

Another similar option to what Dave suggests might be 3D solids. You could use the Extruder to create solids and then merge them today using FME 2022, which has a SolidDissolver transformer. Just a thought, in case you didn't get the meshes to work.

Thank you so much for your responses.
