How Do I Reduce The Number Of Groups In A Model

OK, it dawned on me that my original thread for my problems with 3DC were with textures. Well, that I fixed.
That lead to me asking about the other problems I was having and was I think going off page a bit from my original problem.
So I've started this new thread in order to deal with my current problem. I think if I can get this one solved I can finally get a working shape.
I have too many groups in my model. I get that message saying its over 24 and it's causing the model to have too many nodes. The Blueprint Editor will not process the shape till this is fixed.
So two questions:
1. How to I determine how many groups my model has?
2.How do I reduce the number of groups so it'll end up being 24 or less??
I cant figure it out and either I'm typing in pee poor wording while doing searches on the web and YouTube on how to do this, or there is little or no info......
Specific tutorials for using 3DC or exporting into RW/TS addressing groups have been hard to find... In fact, I've found none.
Thanks
EDIT: I am curious...... Did all these groups come from something I did within 3DC or how the model was made in Sketchup??? If within SU, then the next step would be to rethink the design of the model.
