http://www.pdf995.com/ PDF995 is freeware. I haven't tried it with AutoSketch. It was recommended for use with Xara X1. I use Xara and Expression to illustrate my AutoSketch drawings.
Expression for the Mac is now freeware, too. Expression was bought by Microsoft, and E3 (Mac) is available at their website. The fate of the Windows version remains unknown.
Expression is an application that can send data to Photoshop using the clipboard to create a vector mask. I was able to do this with an AutoSketch drawing by saving to WMF, and converting to AI in XX1. Then load the Ai into E3 and copy and paste into PS CS. You need to bypass the input filters by using the clipboard. M
