How to add "Genesis" figure automatically via script to the scene

Hello!

This is probably a very basic question, but I couldn't find any sample on the official documentation regarding this - I want to automatize the process of:

• Adding a Genesis figure to the scene;
• Import an .obj to the scene (like a shirt);
• Use the "Fit" feature to make the figure use the shirt;
• Render the scene;

The 2nd step I already found on the documentation, however I haven't found a way to add the figure to the scene.

Thanks in advance!
