Design Exchange Format
The VIOSO Design Exchange Format (DEF) is a JSON-based interchange format for transferring supported planning data between applications.
Importing a DEF file
- Open the user menu and choose Import from….
- Choose Design Exchange format (.json) and select the file from your device.
- Experience Designer adds the supported projectors, cameras, and screen to the scene and reports any skipped data.
What is imported
| Element | Imported data |
|---|---|
| Projectors | Position, orientation, resolution, dimensions, throw ratio, and lens shift |
| Cameras | Position, orientation, resolution, and horizontal field of view |
| Screen | A Plane or Cylinder screen |
| Scene units (m / cm / mm / ft / in) | Automatically converted to metres |
Supported units
The DEF format supports m, cm, mm, ft, and in as the units field. Experience Designer converts all values to metres on import.
Unsupported screen shapes are skipped and reported as warnings. The format currently carries one screen descriptor.
Exporting to DEF
To export the current scene in DEF format:
- Open Share → Export to….

.jsonfile downloads immediately.
The export includes supported projectors and cameras. The first supported Plane or Cylinder screen is included; additional screens, unsupported screen shapes, and custom 3D models are not included. Experience Designer reports export warnings when it has to skip data.
