Importing a Speos Light Box

This page shows how to import .SPEOSLightBox, and .speos files into the CAD platform. Importing a light box enables you to retrieve exported geometries, sources and optical properties.

Note: An imported light box cannot be modified.

The imported elements, such as sources and geometries can be used in interactive, direct or inverse simulations only.

To import a Speos Light Box:

Prerequisites: In the case of a *.speos import, make sure all dependencies are available.
  1. From the Light Simulation tab, click Light Box > Import Speos Light Box .
  2. Set the Axis System by clicking one point for the origin and two lines for X and Y directions or click and select a coordinate system to autofill the Axis System.

    The axis system is needed to correctly place the Speos Light Box into the scene according to the axis system of the assembly in which you import it.

    Note: If you define manually one axis only, the other axis is automatically (and randomly) calculated by Speos in the 3D view. However, the other axis in the Definition panel may not correspond to the axis in the 3D view. Please refer to the axis in the 3D view.
  3. If you want to create a dynamic group of objects, in the Trajectory file field, click Browse to load a trajectory file (*.json).

    For more information on trajectory files, refer to Trajectory File.

    For more information on dynamic Inverse simulations capabilities and how to set them, refer to Dynamic Inverse Simulation.

    When a trajectory file is assigned to a Speos Light Box Import and the feature is edited, the trajectory is displayed in the 3D view.
  4. Click in the File field and click Browse to load a Speos component (*.speos) or Speos Light Box (*.SPEOSLightBox) file.
  5. If the exported Light Box is protected, a Password field appears.
    Warning: In version prior to 2023 R1, passwords were not hidden. As soon as you open a project containing passwords, they are hidden and you cannot retrieve them. Make sure to save your passwords in a safe place before opening your project in 2023 R1 or subsequent versions.
  6. Enter the password.
  7. In the Preview section, define the Display mode of the imported Speos light box between Bounding Box and Facet.
    Note: Each time you change the Display mode, you need to compute the Speos Light Box.
    Note: In case of a black-boxed Speos Light Box, the Display mode is automatically set to Bounding Box.
  8. Click Compute to import the file in the current assembly.
    Note: Once the import is completed, the components inherit the information defined during the export.

    If the axis system set for the Speos Light Box Import is edited, you must regenerate the import file manually to get the change displayed in the 3D view.

The Speos Light Box is imported in the current assembly. Sources and geometries are displayed in the 3D view according to the parameters set during the export or hidden in a bounding box and non-accessible in case of black-boxed light box.
