IMPORT CATIA FILES TO 3DEXPERIENCE

Hello everyone, at the moment I am trying to import a huge amount of data to 3DExp and test how long it will take; For example an entire airplane. I want to know the fastest way to do it. With @RK we tried to do it with something called "3DEXPERIENCE PowerBy Import Batch Utility", but i couldn't found it in the Batch Utility.
Today I opened Part design and tried to import the airplane selecting all its elements. I dont know if this is the best way to do it. Besides this window launched when i tried. If someone has already done this before, please give me some advice. Thank you very much. I'll appreciate it.
