Follow the below steps in AutoCAD to create animation (motion path animation):
1} Open the drawing which you want make videos. In the drawing, create a path object for either
the camera or the target. A path can be a line, arc, elliptical arc, circle,
polyline, 3D polyline, or spline.
Note: The path you create is not visible in the
animation.
2} If
the Animations panel is not displayed on the Visualize tab, right-click the
Visualize tab and click Panels ⇒ Animations.
4} In the Motion Path Animation dialog box, Camera
section, click either Point or Path.
5} Do one of the following:
Ä To specify a new camera point, click the Pick
Point button, and specify a point in the drawing. Enter a name for the point.
Click OK.
Ä To specify a new camera path, click the Select Path
button, and specify a path in the drawing. Enter a name for the path. Click OK.
Ä To specify an existing camera point or path,
select it from the drop-down list.
6} In the Motion Path
Animation dialog box, Target section, click either Point or Path.
7} Do one of the following:
Ä To specify a new target point, click the Pick
Point button, and specify a point in the drawing. Enter a name for the point.
Click OK.
Ä To specify a new target path, click the Select
Path button, and specify a path in the drawing. Enter a name for the path.
Click OK.
Ä To specify an existing target point or path,
select it from the drop-down list.
8} In the Animation Settings section, adjust the
animation settings to create the animation to suit your needs.
9} When you have finished adjusting the points,
paths, and settings, click Preview to view the animation, or OK to save it.
Here, in below a sample of animation is presented (which is not so
good looking, only for idea i have attached) which made by following above
procedure. But you can make more sharp animations in solid work and
also in autodesk inventor.solid work and
also in autodesk inventor.
You can make lots of cool 3d videos by using autoCAD. Here I have made an sample video (see below) of a Hand Paint Frame Rack which is using in fabric printing factory. The material of rack various sizes of is GI box.
