Trelis Data Translators


Trelis データトランスレータ


High-quality data interoperability is important for creating a high quality mesh that can be used for analysis. The cleaner the data exchange the less geometry cleanup and decomposition is needed, and that translates into less cost and quicker time to market.

Trelis Data Translators automatically repair geometry and topology, and perform tolerance resolution. With the Trelis Data Translators, there is no need to purchase expensive native programs.


Trelis supports many geometry and mesh file formats, including

File Format File Extension Import/Export
ACIS (.sat, .sab) Import and export geometry
