3 Model the part using DCAD, convert the file format, read it into the application software for animation, set the part, determine the camera andal, specify the transparency, and specify the video. Create the file, assign the video file to the HTML file, and finish the creation.

The present invention is characterized in that parts created by 3D CAD are made transparent by application software for animation, so that complex parts can be made transparent transparently.

However, even in the above invention, since a special program for using the method of creating a moving image data file is required, the user has to obtain an expensive program, and therefore can use it easily. Did not. Even if you get the program, you still have to do the file conversion and various settings yourself by using a special program, and you need to do the operation yourself for it.
