Hi, I'm a mechanical engineering student I'm working on a project of THSA and I have finished sizing the ball screw (lead 40mm nominal diameter 80mm) and know I want to know how to design it on catia because I did some research on google but no result. Here is the ball screw I've chosen(page 104 series 3426 the last one) : https://www.reliance.co.uk/wp-content/uploads/2017/12/Steinmeyer-Catalog-2017-EN-Reliance-web.pdf
Hi, you can probably find a 3D model of this ball screw and nut online, if not from this from some other manufacturer (they are mostly standardized). I am not sure what will you use it for. If you need it as a part of some machine, I would recommend to just model a cylinder with envelope dimensions, because it will save on recourses on your PC, and that is how it's usually done in practice. If you really want to model all features, for the ball screw search for something like sweep cut Catia on YouTube. I am sure you will find something. I am not a Catia user so can't help much there... Regards
