Trajectory Computation (Tip #2141), by Albert Botton, is another great number crunching example. This function draws a representation of the trajectory for objects dropping off a moving conveyor line. Once loaded, type TRJ at the AutoCAD Command line to get the belts moving. Several inputs are required as related to the speed of the belt, pulley details, material details and other dimensions before it calculates and displays the trajectory. A nice set of programming loaded with comments and other useful programmer utilities. |
