Spatial issued a press release announcing the next version of ACIS 3D Modeler and the 3D Interop Suite. http://doc.spatial.com/r19/index.php/ACIS_Release_Notes
I have been impressed with Spatial and their continued focus on interoperability. Of course, I don't think ACIS will ever make it to the de facto standard like Parasolid, nor make it to an industry standard like STEP, but they continue down the path none-the-less putting just enough competitive pressure on Siemens to continue improving. Kind of like AMD is to Intel.
One thing that is very interesting, and I don't know if it is new to ACIS or just new to me, is the 3D Springback for the press metal industry. This one appears to be a part of their analysis suite and focusing on tool and die makers. Personally, I think the real power in this one would be if it can be integrated into the design side as part of the Sheet Metal environment in CAD programs.
Not surprising in this release is the 3D Interop portion being focused on the improved data sharing between Catia v5 and Solidworks. Perhaps Spatial/Dassault is seeing a little pressure from Seimens and Seimen's interoperability between native NX and native Solidedge. Of course, the fact that Catia and Solidworks don't use the same kernel makes the interoperability that much more of a challenge. If Spatial can make Catia and Solidworks share native file formats at least as smoothly as NX and Edge, perhaps ACIS will be the new de facto standard. Keep at it Spatial.
