Generation of a search key shape for identifying a dedicated shape with respect to three-dimensional CAD data is facilitated. A shape group registration unit registers multiple pieces of three-dimensional CAD data; a feature amount computation unit computes a feature amount with respect to each of the registered pieces of three-dimensional CAD data; a clustering unit clusters the pieces of three-dimensional CAD data based on a feature amount; a cluster center computation unit determines a feature amount of a cluster center of each cluster from a feature amount of three-dimensional CAD data; and a search key shape registration unit registers feature amount data of a cluster center as feature amount data of a search key shape.

A programming aiding apparatus that includes a visual program storage unit performs a programming aiding method. In the apparatus, a training data generating unit edits the visual program. A graph learning unit trains a graph learning model that receives a feature of a node and a connection of the node in the visual program as an input, among the input data, and outputs a likelihood of a feature of a node to be added to in the visual program. An added node selecting unit calculates a likelihood of a feature of a node by using data of a visual program as input data input to the learning model trained by the graph learning unit, and selects a node to be added based on the likelihood.
