* For DGN, HOOPS provides basic capabilities to directly import DGN's CAD and wireframe information. To import fully rendered 3D information, a plugin can be used in Microstation to export an HSF file that can be read by HOOPS.
** Tech Soft 3D provides plug-ins for importing 3ds Max as well as Microstation's DGN formats. These plugins are available on the Developer Zone.
*** The importers for these formats are no longer maintained and the functionality is provided as-is. Developers who wish to use these formats and address any issues are free to refer to the MVO HIO-importer source code and modify it as they see fit.
