Which is the good and easiest software for 3D animations(mechanical) - ?

I think that depends if you are in animation, mechanical or architectural drafting.

For one person3D studio max is better than solidworks, since the person works for years with this program and perhaps rarely works with an other program ....

I do not know3D studio max, therefore I only can tell you that I like Solidworks better than AutoCad.. It is every one's opinion which program is better ... 

For making solid models of mechanical parts then3d-max and Solid works is best suited software.

I agree with Mrs. Elke Woofter.

I think Solid Works,. Thank you for your invitation

I agree with experts answer. Thanks for the invitation. .

3d studio max ..........................

Keyshot is easiest software for3D  animation

Cinema4D is a good place to start. A lite version ships with After Effects CC so it is a good first step before you purchase the full program.

the good and easiest software for3d animations is Proengineering
