OD Create Custom Object converts a loaded object into a custom object plugin for Layout. It can either generate a full plugin, or just the custom object data that can be then added to already written code:
Options:
Working Mode: Either write just the custom object data to the clipboard, or create a full plugin structure that can be loaded as custom object plugin into Layout
Save Custom Object To: When writing a custom object Plugin, this defines the output path for the plugin
Custom Object Name: When writing a custom object plugin, this defines the plugin name
Here's a how-to video showing OD Create Custom Object in action.
