Are there user-friendly mechanism design softwares available?

I know you can make mechanisms using popular CAD softwares like Pro/ENGINEER but these packages are a bit too tough to learn and master. I wanted to know the names of any packages that are solely designed for mechanisms where you can design and run a mechanism easily without having to learn the types of mates etc.

SolidWorks maybe, but still there's no easy way around CAD
