I agree with the other sentiments, but as a broad CAD software user it can suggets you will do well to know Rhino and one or more parametric modeller like IronCAD or SW. IronCAD is my pick but it may depend on what company you end up working for. i have had to learn SW and Solid edge and afew others but i chose IronCAD for my own private projects. Much better alrounder and much faster to use and make changes. not many of my collegue had ever heard of it but when i show it to them they are alway impressed. your porolio and your approach to design will be of most value I feel though.
