1. A modeling method for a modeling system capable of designing an object model, said modeling method comprising causing the modeling system to carry out the steps of:

  • conceptual designing in which functional elements including structure and shape of a solid are described as a combination of unit parts with reference to the shape and connections thereof without entering dimension data anddetailed designing in which geometrical elements including dimensions of the solid are described by coded topological elements in a normal projection of the solid without entering shape data, said coded topological elements being coded according to a predetermined sequence which is dependent on a direction in the normal projection so as to include a sequential number in the code,said conceptual designing being carried out with respect to the solid in its entirety before said detailed designing.
