This program demonstrates how the 3D file works.

A brief recap of this program out lines that is is a sophisticated three-dimensional design and display program. Using simple commands, the user may create a solid object or set of objects in three- dimensional space, observe, modify, print and store such displays.

The program includes commands to allow you, the user, to move round the object and look at it from different distances and directions. In this way, we can design a solid object and obtain a sense of its reality in the three-dimensional world. After loading VU-3D from cassette, the user is asked if he wishes to create a new design or set of objects, or whether he wishes to load a data file from cassette. If this is the first time you have used VU-3D, press the option "1".
