Oops, sorry. I didn't get a notification of your response. I'll have to see. There is an amazingly active plugin community on the forums with loads of extensions. It may be I can find something and do a test. Can you tell me what the best / most reliable format to import into MED is (been away a while). Maybe they already have a plugin that goes to that format.

Also a possibly dumb question but is it possible to import some format in to be converted to WED blocks?
