3 Problems

I am converting skp file to off format
I am facing 3 problems:1.I am not interested in the internal structure of the model. I only care for the surface of the model.... How do i delete the hidden geometry of the skp file....
2.Also I would like to reduce the size of the skp file. For this I do not want to use repetition of the component as when I convert to 'off' format it tends to obviously increase. Anything like reducing based on the number of vertices or number of surfaces(triangles)
3.Also I would to have all d normals in an skp file in one direction. How do i do it....
I really do not know much of ruby... any help is really appreciated... thanks...

#1 - Hidden geometry means geometry that has been made hidden by the user - its a setting in SketchUp. Geometry inside a building, for example is not hidden geometry. You could call it internal geometry maybe. Which are you trying to avoid exporting? You can test each face if it is set to hidden, and not export the hidden ones. There is no easy way to avoid exporting internal geometry though. It will probably just need to be cleaned manually.
#2 - This is somthing that must be done while modeling. Instead of making circles have 24 sides, the user should set circles to have fewer sides to cut down on vertex count. There is a plugin out there that helps reduce poly count automatically though. I don't rememeber if it is on this forum, or the sketchup ruby depot, or smustard or what though.
#3 - SketchUp does not give any control of normals. I think they always face the same direction as their face. Unless the edges is smoothed, then I think the normals average between the normals of the 2 faces. I think.

Nope! The normals stay the same. You can see with if you use my Probes plugin - it lets you visualize the normals of faces and edges: http://forums.sketchucation.com/viewtopic.php?f=323&t=21472#p180592
