The models were aligned to the origin in standard orientation. It was one of the things I personally checked to make sure this wasn't a factor. I'm not 100% sure, but it seems to me that all features like edges, groups, components, and planes, are ignored in the conversion from SU format to STL format and none of this information is saved with the model. When you use the export STL plugin from the Extension Warehouse you need to select all parts of the model you want to convert (I just go CTRL-A), choose the format (binary or ASCII) and the units and away it goes. If you haven't exploded groups/components and turned off edges it will tell you it has ignored these things in the process of creating the STL file. This is what leads me to assume that things like datum planes are also being ignored in the process. I need to workout how to reorient the model in Pro E by inserting new datum planes... which I don't know how to do yet. Maybe if I could export the SU file as some other format that preserves these features that would solve my problem???
