Files with hsf suffix can be found as 3D models based on the HOOPS file format which is used for sharing visualization data between disparate engineering applications.

There is one other file type using

HSF file - HOOPS 3D graphics

What is hsf file? How to open hsf files?

File extension hsf is probably best know for its use for HOOPS Stream format. The OpenHSF Initiative is an industry-wide effort to establish HOOPS Stream Format (HSF) as a common, open and rich streaming format for sharing visualization data between disparate engineering applications.

HOOPS .hsf file format is an old 1980s and 1990s file format originally created by Ithaca Software of New York State. They eventually went broke, leading years later to their technology being bought up by a new company called TechSoft America. TechSoft wanted to resurrect the old HSF file format as a modern 3D WEB streaming file format, but the dotcom bust took out the steam from that initiative. TechSoft would then create some custom 3D file viewers for other companies in the early 2000s which would use HSF as their internal file format. While HSF faded over time, it eventually found its way into the new 2006-era DWF-3D file format and DWF-3D viewer from Autodesk (of which the 3D data is stored within the DWF-3D container file as the HOOPS HSF 3D file). Another viewer created by TechSoft for SolidWorks Corp. woud end up seeing the HSF file format be used as the basis of the SolidWorks .easm encrypted format (it is basically a HSF file but with encryption).

OpenHSF represents the only truly open visualization format geared specifically toward engineering, making it the ideal solution for sharing visual models between the myriad of applications used within the greater PLM marketplace.

Supported by dozens of software vendors and end users and already imported/exported from a wide range of popular applications, OpenHSF is enabling lightweight 2D/3D models to move smoothly through concept, design, analysis, manufacturing, marketing, e-commerce, maintenance and end-of-life phases that make up the full product life-cycle.

The default software associated to hsf file type:

HOOPS is a 2D/3D development platform for creating or enhancing professional-grade applications. HOOPS’ rich set of API’s enable developers to work from a very high level.

Help how to open:

Primarly use HOOPS to open and edit .hsf stream files. But it is likely that more program exists which could be used to work with .hsf files.

How to convert:

Some 3D translation tools like PolyTrans|CAD+DCC can convert .hsf files to other 3D models.
