How to convert ACIS SAT (.sat,.sab) to 3MF?


PolyTrans|CAD+DCC performs mathematically precise CAD, DCC/Animation, GIS and BIM 3D file conversions into all key downstream 3D packages and file formats. Okino software is used and trusted throughout the world by many tens of thousands of 3D professionals in mission & production critical environments, backed by respectable personal support directly from our core development team.

     

ACIS SAT

ACIS 'SAT' (ASCII) and 'SAB' (binary) are the native 3D file formats of the Spatial ACIS solids modelling toolkit. Spatial licenses this toolkit to third party developers upon which they can develop their own 3D software and/or converters.

From Okino's own perspective, the ACIS SAT file format was more prevalent and popular in the late 1990s and into the early 2000s. However, thereafter, several major software vendors moved off of the ACIS platform and onto other alternative platforms to build their software. We really do not have any of our customers utilize the SAT file format anymore as there are better or more native methods to source such MCAD data (such as STEP, IGES and Parasolid).

     

3MF

3MF, 3D Manufacturing Format, is a modern replacement for the legacy STL (StereoLithography) file format with an explicit focus on the proper transmission of CAD and non-CAD model data for 3D printing as well as to downstream services and platforms. From Okino's long term perspective, the VRML2 file format was and is "just as good" for such requirements but never had the correct understanding nor traction since its introduction in 1995.

Features of 3MF over the legacy STL format includes: geometry instancing support, layered texture maps, multiple layers of UV texture coordinates, vertex colors and extended material types.

History, features, overviews, implementation partners and more can be read on the 3MF Consortiumís web site.

Note: Microsoft Windows uses the 3D Manufacturing Format (.3mf) for all 3D printing tasks.
