copy_if_not_exists(src, dst)

Copy a file from source to destination if it does not already exist.

This function checks if the destination file exists. If it does not, the function copies the source file to the destination using a high-level file operation that preserves metadata.

Parameters:

• src (str) – The path to the source file to be copied.

• dst (str) – The path to the destination where the file should be copied.

copy_presets(addon_prefs)

on_blender_startup(context)

Checks for any broken computations on load and resets them.

This function verifies the presence of necessary Blender add-ons and installs any that are missing. It also resets any ongoing computations in camera operations and sets the interface level to the previously used level when loading a new file. If the add-on has been updated, it copies the necessary presets from the source to the target directory. Additionally, it checks for updates to the camera plugin and updates operation presets if required.

Parameters:

context – The context in which the function is executed, typically containing information about the current Blender environment.

on_engine_change(*args)

fix_units()

Set up units for Fabex.

This function configures the unit settings for the current Blender scene. It sets the rotation system to degrees and the scale length to 1.0, ensuring that the units are appropriately configured for use within Fabex.
