Patent ID: 8355023

Claim:
A drawing generation device for electric cable housing components, which converts three-dimensional data of electric cable housing components generated by a three-dimensional arrangement adjustment CAD into two-dimensional data by using a computer, and outputs the converted data in the form of drawing, the computer comprising: interface means for performing input/output of various instructions and data; two-dimensional data generation means for processing the three-dimensional data of electric cable housing components to generate a drawing of the two-dimensional data; and storage means for storing three-dimensional data of electric cable housing components that is acquired by the interface means or another means, as well as two-dimensional data of electric cable housing components that is obtained as a result of a process performed by the two-dimensional data generation means, wherein the two-dimensional data generation means comprises: data reading means for reading the three-dimensional data of electric cable housing components that is stored in the storage means; diagram generation means for converting the three-dimensional data of electric cable housing components, which is read by the data reading means, into a line segment for each component, and converting a contact part between the components or a part where the components partially overlap with each other, into an intersection point, to convert the three-dimensional data of electric cable housing components and generate a diagram composed of the line segment and intersection point; coplanarization means for projecting the line segments of a plurality of components that overlap with each other in a vertical direction on the diagram generated by the diagram generation means, onto a single plane which is orthogonal to the vertical direction, and shifting the line segments along the single plane so that each of the line segments is disposed in a different position from other line segments thereby representing the vertical overlap on the single plane; file output means for outputting, from the interface means, the two-dimensional data of electric cable housing components that is obtained by the diagram generation means and the coplanarization means, in the form of file, and storing the output two-dimensional data in the form of a file in the storage means.
