File Formats
HOOPS Access allows developers to read and write a wide range of popular CAE file formats through a unified interface. An application built on HOOPS Access will be able to use the same source code to import, extract and export data for all these formats.
Although most of the readers and writers are proprietary code from Tech Soft 3D, some do rely on a vendor API. For these formats, marked by a (*) in the table below, an agreement with the vendor is necessary to ship their API in your end-user application.
