how do I make the senseFly Duet T Thermal Mapping Camera in Catia V5?

Need step by step solution on how to design this sensor . But I dont need the accurate design of it. Just a simpler version of it will do because this is just for a project. I dont have that much time to do the precise designing in Catia that is why im asking if anyone can help to create a simpler version of this sensor. Thank you!
