The custom attributes are for picking, selecting and modify.

The model is generated from an architectural model where the basic 
elements are walls, roofs, windows etc.  When the program generates 
the model, adds a custom attribute with some information to retrieve 
the original elements (layer, type of element and an index).
When the user click on the model in selection mode, the attribute 
indexes to the original element, the program generate a little model 
of it and the user can drag, double click, change the dimension etc.

Yes, I could save 2 different models, an optimized model for a fast 
navigation and the original model for picking, selecting and 
modifying.
The other way could be to modify your optimizing code to copy the 
custom attributes of polygon and general polygons to the faces 
attributes of the meshes. What part of the code should I look for 
this modification?

Thanks again.
