Hello everyone! I am from South Australia and am very excited to start working

Hello everyone! I am from South Australia and am very excited to start working on a F1 Car RC project. I would like to personally design as many of the parts for the car in CAD.
For a big project like this, I am a bit unsure of where to start. Are there any specific videos/texts I should watch? Do you guys have any tips for a beginner?
Is there any good example file on grab CAD?
