My husband is a journeyman pipe fitter and is working pipelines. He recently bought a TI-89 calculator because a buddy has one that displays take-outs for fittings and calculates cut lengths on fittings for odd angles. Can the Piper Suite do this? Can Piper Suite be loaded to the TI-89 and provide this info? Do you know of any other program that could do this and be loaded on the TI-89? Thanks for all your help.
