Line Quantity Reducer ?

[Matte]

Hi All,
What would you recommend as the best way to reduce the number of line segments in a 3D Sketchup model? I import stuff modify it and something that looks like 1,000 lines comes up with 245,000 small line segments when I run the "Solid Inspector" plugin! I'm willing to accept a little less detailed model to reduce this to something (usable). I can always redraw a few areas if too much is cleaned up. The 3D models are for export to .STL so I can run it through a 3D printer.... It doesn't like to print 245,000 little lines? Thanks in advance for any advice you may have.
