Computer aided graphics as an aid to mechanism design

A computer program used to generate accurate scaled diagrams of mechanisms is described. The program contains 16 subroutines which are written using an integrated graphics software system called DI-3000. Each subroutine can be called, using several arguments, to generate a computer-aided drawing of a basic link group of a mechanism. In this manner, an accurate diagram of a complicated mechanism, either in a single position or a sequence of subsequent images, can be generated by a simple program containing only several statements
