We have recently updated the SketchUp SDK for folks who need read and/or write SketchUp 7 files. It is available on http://code.google.com/apis/sketchup/docs/downloadsdksubmit.html. If you have feedback or questions, please post your questions or suggestions to the SketchUp SDK Group. If you would like to be notified about future SDK updates and news, please subscribe to this blog, if you haven't already.
Happy SketchUp Developing!
