Bill,
Were you ever able to save the .SKP where you wanted them?
I tried saving it with the base name (xxx.skp) and no path. I don't think it resaved it, althoug it returned true.
sname = File.basename(sfile)
model.save(sname)
I then saved it with new names using:
component_name = File.basename(sfile,".*")
sname = component_name + "_new.skp"
model.save(sname)
This seems to have worked (saving a new SKP in the original folder)
