You have a part on my profile and you can download it. There can you see how is it created. Contact me for questions,

Thanks :)

I would prefer to model most of the Standard Parts in Mechanical Desktop 6... it is fast and Quick for Standard Parts....
MDT6 has inbuilt program for all standard parts....

Hi,
I've just launched a new course on PARAMETRIC DESIGN in CATIA.

It's comprehensive course with multiple examples so if you are interested just give it a try.
