Geometry Definition: How to write this instance

Hello,

Whilst looking at ifc and revit files, I saw that some instances are written away as Geometry Definition and Geometry Instance.

I was wondering how you do this in FME. I was looking at the GeometryPropertySetter but I dont' see any possibility to write away geometry definitions.

I also looked at https://knowledge.safe.com/articles/54027/creating-and-using-geometry-instances.html#:~:text=A%20geometry%20definition%20is%20a,and%20a%203D%20affine%20matrix.&text=This%20is%20especially%20true%20if,is%20very%20large%20or%20detailed.

But I could't really work it out myself.

Anybody can point me in the right direction.

Kind regards,

Andreas
