To the individual with spanners and 'ammers? None of them.

Dear Mustafa

The most important think is to have your Owen mind strength in mechanical engineering , imagination is one of the most important tools your mind should use, Softwares can only improve the efficiency of GOOD engineers, but can not create them.

softwares like Solidworks, solid edge , auto cad, pro engineer, staad pro and many can be help full, in case you have the strong backgrounds

The most important software in engineering is the one you are able to use very well for the purpose it was made for. There are so many solutions available for so many different things, and so many news in the market every year, that is useless try to get to an ultimate solution or the best that money can buy. Useless. You make the things happen, not the software. It's much better to use "paint" to make a good part drawing for manufacture being able to specify correctly the material, tolerances, and all important things in the very cheapest way, than use a complete soliddesignedge-bert software and "forget" to specify something important, and imagine that that part is the anchor bolt for that child restraint system in the new space wagon family that was involved in a car crash. How would you feel about it?
