Hi
My name is Alex, and I am a Design Engineer.
I have been working for more than 18 years with Catia in automotive engineering, racing and industrial design.
All the knowledge and experience that I gained helped me work with companies like
Ferrari Formula One Team, Red Bull Racing, Jaguar Land Rover, Aston Martin and others
In this course I teach Electrical 3D Harness Design with Catia 3DEXPERIENCE
Catia 3D EXPERIENCE is a cloud-based software released by Dassault Systemes that is very similar with Catia V5 and Catia V6
This software currently replaces Catia V5 Student Edition and can be purchased at a very low price from their website. This cost is for a 1-year license.
I talk about more details in the “Watch this first” video that is free to view if you check out this course
Catia 3D EXPERIENCE is a cloud-based software released by Dassault Systemes that is very similar with Catia V5 and Catia V6
First, I show the commands we will use and then we make a project to practice what we have learned
At the end I made some videos with information and theory about materials and components used in electrical harness manufacturing
If you are not an electrical engineer, I made some videos where I explain electrical components that will help you understand this course better
You can use Catia 3D Experience instead of Catia V5 with my other courses where I provide step files to do the exercises.
Thanks for watching this video and see you in the course.
