transform 3d model to line orientation

Hi @charry​ are you looking to transform the 3D model into 2D Geometry? If so you can use the 2D Forcer transformer.

I'm not too familiar with matrices and quaternions myself, but if you want to extract that information you can use a Chopper transformer on your feature to separate it into points, lines, and polygons, and then use a PointPropertyExtractor to extract the matrices and quaternions.
