Importing from Sketchup - via file or Datasmith - Size differs

Screenshot 2022-01-11 133929Hi Everyone...

I am importing a simple model from latest SketchUp Pro to Latest Twinmotion 2022.1 preview 2.

units a metres both software models

Model 1 is via Datasmith - it is correct scale in TM

Model 2 is via Skp File import - is is about 30% of the correct scale.

Orientation is also different with both imports

By file, the model integrity is good

by DS, the file has some invisible faces [no they are not reverse faces]

(solved this issue - the backface material for kerb was not the default colour... it was another material)

A Bug? Any Ideas?
