I have written this program to make it easy for anyone to make computer graphics based structrual design of simple compounds. (User can also make very complex chemical structures but he/she will need a clear idea of 3D geometry and some basic trignomeric (it is a branch of math) skills.) This progarm takes a text file containig code to design a chemical as input. User can write his own design code in a text file and use it to draw any chemical on the computer. The design code for a chemical follows a predefined pattern. If this pattern is not followed in the design file then the program will give an error message and exit. User can view the chemical from any angle he wishes. To make is easy to see the chemial structure while designing I have added the wire-view mode-　I have written this program to make it easy for anyone to make computer graphics based structrual design of simple compounds.
