I would like to know which is the best and each of these programs specialty .
I took a course at my uni that taught me ProE, and now I am doing my internship in a company that uses Catia. And some people have been saying Unigraphics is good too
I cant find a quiet good answer by surfing on google an I am very confused at the moment
No program is the perfect answer for all. They all have strengths and weaknesses and we all have our preferences built on familiarty. The best thing is to have a knowlege of more than one system and develop the skills to learn each sysytem put in front of you as quick as possible
