ok not sure if this is the right forum but i guess so

i am writing a software that has a result form (eg 3d qube)
and smal parts and hase to calculate how the small parts fit in to the finishing form ..like a 3d puzzle.

now i do not know how to save the data of these 3d forms pieces how ever you want to call them. first i thought of a 3dimensional array but wanted to ask if there is a nother easier or better way of sving 3dimensional information ??? you get it??

thanks for the help in advance
