New user looking to import Google sketchup skp files into blender.


I am looking for information on importing my models from Google sketchup into blender to start using the program. Unfortunately it seems this file type is not supported, is there anything I can do?

Export as .dae files from sketchup which blender can import

there are sometimes problems with the models imported from Sketchup, especially faces that are supposed to be transparent, and there are often rendering problems with a “dirty look”.
just wondering if there were any tips, as in the best format to use, .dae, 3ds, obj?
and also are there any tips for preping the files for export in sketchup?
Thanks in advance
