Hello another time, need help on Catia v5!

I tried to make a cable car cabin using this document which is under Solidworks: https://technochamandier.files.wordpress.com/2017/02/tutocabinesolidworks.pdf but I work on Catiav5 and it's the first time I've used this software I don't master it.. in fact I am a 2nd year student preparatory classes I need help on my TIPE project "Urban Cable Car" it was a drawing to practice only .. I want to draw these cable car components with exact measurements and in other ways, but I need someone who knows Catia to help me, I'm the one who will do the work, I just want someone to guide me. Thanks in advance 
Kind regards.
