you know what i can't stand about gibbs. if you spend the time to make a sheet of parts and create the code for them (operations) save them as your cnc file you can not reload these back into gibbs to make changes in case of a mistake. once you clear the wells and save your program you can't bring them back like you can in a much simpler program Bobcad. you have to recreate the whole parts sheet over again. if you have allot of parts on the sheet this can be a real hassle. :.(
