3d animation program search

[Sierra]

hello to all, I apologize if I have wrong section, I would need a program that allows to create 3d animations of the various components of an object, which assemble to then shape the final object. Usually on the web there are many of these animations, but generally in the mechanical-industrial context, I would need a program that allows to do so in the building-civil field.
Thank you in advance for your help.

all animation programs allow you to create animations of objects that self-assemble. try with blender that is free.

the autodesk produces some, take a look at their site.
What programs do you use to make your designs? it would be appropriate that the animation program was compatible with your cad, redesigning everything would be a considerable time use

thanks to all for answers, I use autocad mainly, and I saw 3d studio max, but I noticed that it is quite complex. .
