# Working with FBX Scenes Linked to the Original Files

When importing an FBX file in an Action schematic, setting FBX Import Type to the option Link to Original File does not create a Geom node like Create Local Copy does, but rather creates an FBX Scene node.

You cannot perform the same operations on an FBX Scene node as on a Geom node.

- You can only parent Axis nodes.
- You cannot parent it to other nodes.
- You cannot select individual components; you always select the entire scene.
- There is only one node in the Priority Editor for the whole scene.

If someone updates the linked FBX file, click Refresh to update the FBX Scene node in Action.

The options available in an FBX Scene node are also different from the ones found in a Geom node.

FBX Scale field
  Displays the factor by which to scale the FBX scene. Does not scale the camera if it has already been extracted using the Extract Camera button. Editable.

Extract Camera button
  Click to extract the FBX camera from the FBX scene. It extracts and creates a new FBX camera node, scaled to the current FBX Scale . Once extracted, the camera is no longer linked to the FBX scale: changing the FBX scale does not affect the camera. If you need to edit then rescale the camera after changing the FBX Scale, delete the extracted camera and extract a new one.

Sort button
  Enable so the 3D models contained in the FBX Scene are drawn according to their normals. Consider using this option if the scene contains semi-transparent 3D models to ensure they are correctly drawn.

FBX File Path field
  Displays the path to the FBX file. Click to replace the currently displayed FBX scene with another one.

Refresh button
  Click to update the FBX Scene node with the content of the FBX file. Use this if the FBX file has been updated since its import.
