I noticed that Mark Flyler over at Imaginit posted a great article on pulling images from Inventor to be used as technical illustrations, Power Point or on web sites. You might simply want to get an image directly from your Inventor screen or perhaps a more customized image rendered from Inventor Studio. Mark starts out with the basic and works his way to Inventor Studio (including a few tips for using in Power Point). If you have ever needed to capture images out of Inventor, head on over to his blog post.
Nicely done Mark!
