Apparatus and method of producing 3D structural sketch and computer-readable recording medium on which computer program for executing the method is recorded

An apparatus and method of producing a three-dimensional structural sketch (3DSS) and a computer-readable recording medium on which a computer program for executing the method is recorded are provided. The apparatus includes a property-detecting unit detecting a unary property of each part of a predetermined two-dimensional sketch and relational properties of the parts; a node-generating unit receiving the detected unary properties and the parts and converting the parts into nodes having three-dimensional shapes together with the detected unary properties; and a node-arranging unit receiving the detected relational properties and the nodes, arranging the nodes according to the detected relational properties, and generating a three-dimensional structural sketch, wherein the unary property includes geometric property and the relational property include topologic property. Thus, the apparatus can easily produce a 3DSS and update the produced 3DSS.
