2D Modeling

two dimensional modelling is a far more complex operation than one dimensional modelling. drawing devices in 2d is often a challenge and the noding process is far more difficult. finally, 2d modelling needs computers with a larger amount of memory space. the requirements for 2d modelling is now being met by personal comuputers as memory costs have fallen and memory sizes approaching a 1 gbyte or more are possible. historically 2d and 3d programs have been on unix but they may move to pcs.
