There are 2 types of DFX files, Polyline or Face. Bryce will import both, but it has a harder time converting a Polyline ( which is strange because it's usually the smaller file size of the 2 ) If the file is a big size it could very well be crashing Bryce. But I used to experience the same thing. I couldn't import any DFX files ( no matter which type they where ) It seemed one day Bryce just quit importing them, ( even files I was able to import at an earlier date ) Guess something got corrupt or changed the way my machine read DFX files. When I finally did a reformat to my hard drive Bryce started importing DFX and has ever since.
