Hi all
 
I am a new user of cadforum.

Besides that i am looking for a software that able to draw a 3D drawing with animation due to i am a technician which in R & D gruop and required lot of 3D drawing with animation in my presentation.
 
Thanks for the favor. Appreciate that

You can find a LISP utility to draw 3D and 2D spring in AutoCAD here on the Download page.
For animations I would recommend a more suitable application like Autodesk VIZ, 3ds max or Inventor.

This is the Inventor Forum, you should post in the Autocad forum if asking Autocad question

you also might try blender thats mostly for game animation but it is entirely free and you can custom set the physics... there are better programs out there for 3d design and animation than autocad as well i'm just not familiar with them
