How can I simplify my 3D bounding boxes of pointclouds so that they aren't 3D polymeshes on output but simplified 3D solids? Also is there a way to merge them at the same time into one 3D solid?
This is my workspace as it is at the minute

Hi @samstibbs73, in the FME Geometry Model, there are some types belonging to Simple Solid. See here to learn more: FME Geometry Model
Your workflow generates Extrusions, which is also a kind of Simple Solid. If Extrusion doesn't satisfy your requirement, which type of Simple Solid do you need to create?

Hi @samstibbs73,
To creste the simplest possible geometry within FME, you can create a Box from the Pointcloud bounds.
After the BoundsExtractor, add an AttributeCreator to create the attribute _geometry from the text below:
<?xml version="1.0" encoding="US_ASCII" standalone="no" ?>
<geometry>
<box>
<minCoord x="@Value(_xmin)" y="@Value(_ymin)" z="@Value(_zmin)"/>
<maxCoord x="@Value(_xmax)" y="@Value(_ymax)" z="@Value(_zmax)"/>
</box>
</geometry>
Next, add a GeometryReplacer with the Geometry Encoding set to FME XML and the Geometry source set to the attribute _geometry. This will replace your pointcloud with a 3D Box from the bounds.
If you want to merge them, you can try the FME Hub transformer SolidDissolver. However the output of this will be a Brep solid.
