ridge line or slot, of the basic shape data, a receiving device (22) which receives from the
client terminal device (40) related form data that is different from the basic form data and describes an article related to the article, based on the stored basic form data, wherein the storage medium (23) stores the referenced form data, a
data acquisition device (24) which captures the basic form data and the related form data, a determination tool (25) which determines that a predetermined condition is satisfied if a shape and a position of at least one related element of the related shape data matches a shape and a position of at least one base element of the base shape data such that the related element and the base element are similar, an association means (26) which, when the predetermined condition is met, identifies the basic attribute information of the at least one basic element whose shape and position correspond to the shape and position of the related element; related attribute information which includes the identified basic attribute information, which is a tolerance zone class, a hole
diameter, a distance between centers, a hole type, a hole style, a dimension, a
surface finish, an
effective depth, a full thread length, a slot width tolerance, an appearance plane, a
surface roughness, first tolerance information relating to a tolerance in respect of a distance between the elements, or second tolerance information relating to a tolerance in respect of a dimension within the elements;associated with at least one related element of the related form data and which stores the related attribute information in the storage medium (23), and , a quotation means (27A) that creates quotation information of an article corresponding to the referenced form data, based on the referenced form data and the referenced attribute information stored in the storage means (23).
