which softwares are neccessary for a mechanical engineer to learn?

Answer 1

In college, most mechanical programs will run you through autocad...2008 is out and its nice. Our program will require you to take SolidWorks and learn to use Cosmosworks. For electives, you can take Pro E, Autocad Inventor, or a finite element program like staad. But every mechanical workplace is different, and each has their favored program....if you become proficient with any 3d cad program and its analysis package, you'll do just fine and learn there's quickly.

Answer 2

Apart from Autocad which has gained almost universal usage in one form or another, most software used by engineers is in most cases limited to the software in use by the engineers employer.
Most engineering firms have approved software that they furnish and require that their engineers use. This standardizes design and calculation methods for the company (which save lots of time and confusion) and also means that someone has taken the time to verify that the computer programs will do what they say they will.
The company programs usually have all been verified.
If each engineer used his own favorite programs, every engineering office would be like a towerof babel, and checking someone elses work would require that the engineers would have to learn many other programs.
