LDCad Set PBG generator

[Orion Pobursky]

Found a problem with 298c02 part :
For example set 76042-1 or 7236-1 have 2 of it but in the export there are only 1x4592 +1x4593.

That is indeed a bug but not a serious one. The cross ref code doesn't take quantity into account but LDCad doesn't do anything with quantity at the moment so it shouldn't affect the ability to use the PBG effectively. I'll push a change shortly.

When 298c02 is exported in 2 sub parts (i prefer this solution), why 2429c01 is not ?

This is because the two parts of 2429c01 never come as different colors. Therefore it is trivial to add the part to the model and then inline it.
