  • Geometric constraint condition displaying apparatus
    Patent number: 5784063
    Abstract: A geometric constraint memory processing section causes a data memory section to temporarily store geometric constraint conditions inputted by an input unit. A geometric constraint display data processing section creates geometric constraint display data from individual items of geometric constraint data read from this data memory section. An assembly processing unit shifts solid shape data created by a solid shape creating unit within a display space on the basis of the geometric constraint data and thus creates three-dimensional model display data. A display processing unit displays all the geometric constraint conditions in superposition on the three-dimensional model displayed by the three-dimensional model display data.
