Hide Geometry Url Of .DAE

Hi,

I am playing around with the .dae and Noticed that a cube only uses 1 geometry url which is ID2, However the models that are more complex have around 13 Id’s is there a way to edit the file so that the 13 ids have 1, I am exporting from sketchup and then converting into o3d.

Simon

What are the 13 ids for?
