Three-dimensional shape data editing device, and non-transitory computer readable medium storing three-dimensional shape data editing program

A three-dimensional shape data editing device comprising a processor configured to,

• with regard to a first three-dimensional shape configured using a plurality of forming surfaces of at least one of flat surfaces and curved surfaces, and a second three-dimensional shape in which an object represented by the first three-dimensional shape is configured using a plurality of three-dimensional elements, convert the second three-dimensional shape into a third three-dimensional shape represented by the forming surfaces,
• extract edges of the object from the first three-dimensional shape,
• specify edge forming surfaces that correspond to the extracted edges of the object, from among the forming surfaces in the third three-dimensional shape after conversion, and
• configure the edge forming surfaces of the third three-dimensional shape such that shapes of the edges of the object represented by the first three-dimensional shape are reproduced.

A non-transitory computer readable medium storing a three-dimensional shape data editing program causing a computer to execute a process comprising:

• with regard to a first three-dimensional shape configured using a plurality of forming surfaces of at least one of flat surfaces and curved surfaces, and a second three-dimensional shape in which an object represented by the first three-dimensional shape is configured using a plurality of three-dimensional elements, converting the second three-dimensional shape into a third three-dimensional shape represented by the forming surfaces;
• extracting edges of the object from the first three-dimensional shape;
• specifying edge forming surfaces that correspond to the extracted edges of the object, from among the forming surfaces in the third three-dimensional shape after conversion;
• and
• configuring the edge forming surfaces of the third three-dimensional shape such that shapes of the edges of the object represented by the first three-dimensional shape are reproduced.
