Development drawing creation system and development drawing creation program

摘要

Provided is a development view generation system including a storage unit that stores information on a three-dimensional shape of an article, a development surface determination unit in which when there is a second surface adjacent to a first surface, the first surface being a determination target, and there is a third surface adjacent to the first surface and the second surface, if an angle between the first surface and the second surface and an angle between the first surface and the third surface are a pre-set threshold or less, the development surface determination unit determines the first surface as a development surface, and if any one of the respective angles is greater than the threshold, the development surface determination unit determines the first surface as a non-development surface, and a development view generation unit that generates a development view, for a surface which is determined as a development surface.
