= supported
= partially supported
= functionality provided as-is

## 3D Formats

File Format | Import | Export | Third party package | Platforms |

DWG |  |  | RealDWG or HOOPS Exchange | Windows |
DGN * |  |  | DGN Direct | Windows |
HSF |  |  | n/a | All |
HMF |  |  | n/a | All |
U3D |  |  | Windows |  |
PRC |  |  | HOOPS Exchange | Windows |
PDF (2D/3D) |  |  | 2D supported is native, 3D PDF requires HOOPS Exchange | Windows, Linux |
OBJ |  |  | n/a | All |
PLY |  |  | n/a | All |
SKP |  |  | SketchUp | Windows |
STL |  |  | n/a | All |

Please see the library compatibility table in the Release Notes for the required versions of third-party packages.

* 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 supported 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.
