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

A method of producing a three-dimensional structural sketch, the method comprising:

• detecting a unary property of each part of a given two-dimensional sketch and relational properties between the parts;
• 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
• 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 includes topologic property.

At least one computer-readable recording medium storing instructions that control at least one processor to perform a method of producing a three-dimensional structural sketch, the method comprising:

• detecting a unary property of each part of a given two-dimensional sketch and relational properties between the parts;
• 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
• 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 includes topologic property.
