Development view generation system and non-transitory computer readable medium storing program

A non-transitory computer readable medium storing a program causing a computer to function as:

• 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, among surfaces forming the three-dimensional shape of the article, if an angle between the first surface and the second surface is a pre-set threshold or less, and an angle between the first surface and the third surface is the 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 along a pre-set reference surface, for a surface which is determined as a development surface by the development surface determination unit.
