1. A design aiding apparatus comprising:
- a retaining unit to retain plural pieces of shape information in a first form about respective plural registered components which may constitute a structure;
a first extracting unit to extract plural pieces of feature information from the plural pieces of shape information in the first form about the plural registered components, respectively, retained in said retaining unit;
an obtaining unit to obtain a piece of shape information in a second form about a structural component constituting the structure;
a second extracting unit to extract a piece of feature information from the piece of shape information in the second form about the structural component obtained by said obtaining unit; and
a retrieving unit to calculate degrees of similarity of each of the plural pieces of feature information about the respective registered components extracted by said first extracting unit to the piece of feature information about the structural component extracted by said second extracting unit, and retrieving a registered component whose calculated degree of similarity is equal to or larger than a predetermined degree as a similar component of the structural component, wherein said first extracting unit and said second extracting unit extract frequency distribution of distances from the shape information as the feature information by extracting arbitrary two points on a shape represented by shape information in the first form or the second form and calculating a distance between the two points a predetermined number of times.

Abstract
An apparatus comprises a retrieving unit calculating a degree of similarity of each of the plural pieces of feature information about the respective plural registered components extracted by a first extracting unit to the piece of feature information about the structural component extracted by a second extracting unit, and retrieving a registered component whose calculated degree of similarity is not less than a predetermined degree as a similar component of the structural component. Even if shape information about a component to be newly added to design data of a structure is in a form that is difficult to be used as the design data, it is possible to easily add the shape information about the component in a form that is usable as the design data to the design data.

7. A design aiding method comprising:
-
first extracting plural pieces of feature information from plural pieces of shape information in a first form about a plurality of registered components, respectively, in a retaining unit retaining the plural pieces of shape information in the first form about the respective plural registered components which may constitute a structure; obtaining a piece of shape information in a second form about a structural component which constitutes the structure; second extracting a piece of feature information from the shape information in the second form about the structural component obtained at said obtaining; and calculating degrees of similarity of each of the plural pieces of feature information about the respective plural registered components extracted at said first extracting step to the piece of feature information about the structural component extracted at said second extracting step, and retrieving a registered component whose calculated degree of similarity is equal to or larger than a predetermined degree as a similar component of the structural component, wherein, at said first extracting and said second extracting, frequency distribution of distances is extracted from the shape information as the feature information, the frequency distribution of distances being obtained by extracting arbitrary two points on a shape represented by shape information in the first form or the second form and calculating a distance between the two points a predetermined number of times; and wherein the method is performed using a processor or a computer. - View Dependent Claims (8, 9, 10)
