A device even at the time of initial planning of plant design easily and rapidly generates three-dimensional arrangement adjustment CAD data which describes a route for arrangement of cable housing components. An area generation sectiongenerates a prescribed rectangular parallelepiped area from the minimum and maximum coordinates. A cable information acquisition sectionacquires information relating to cables such as cable specifications, starting point information, and end point information. A route generation sectiongenerates a cable housing component route between a starting point area and an end point area through via areas. A route consolidation sectionconsolidate into a single route any route having the same cable specification, starting point information, via information, and end point information. A three-dimensional model conversion sectionadds a prescribed width and height to the consolidated route to generate a three-dimensional cable housing component route model.

Generation device of three-dimensional arrangement adjustment CAD data for cable housing components, and control method and control program for same

To make possible using three-dimensional data of electric cable housing components to automatically generate and output a drawing that is simple and useful as two-dimensional data for clearly representing the relationship between upper and lower components. Determination controllerof two-dimensional data generation unitconverts three-dimensional data of electric cable housing components, which is read by the data reading part, into a line segment for each component by diagram generation part, and converts a contact part between components or a part where components partially overlap with each other, into an intersection point, to generate a diagram composed of the line segment and intersection point. Determination controller, by coplanarization part, shifts line segments of a plurality of components that overlap vertically on the diagram onto a single plane, and slides the line segments at a predetermined interval to represent the vertical overlap on the plane. Determination controlleroutputs the generated two-dimensional data of the electric cable housing components from interface unitin the form of file by file output part, and stores the data in the form of file in storage unit

In three-dimensional data generation unit, data edition unit, generates a spreadsheet data that includes information relating to a plurality of node points on a continuous arrangement route of target components by interactive process with a user, and stores the data in storage unit. Three-dimensional data conversion unit, on the basis of spreadsheet data, arranges the node points in a three-dimensional space, connects node points having a predetermined relationship using line segments, and imparts cross-sectional shapes to the connected line segments, to carry out thereby conversion into target component arrangement three-dimensional data. Three-dimensional data management unitstores the obtained target component arrangement three-dimensional data in storage unit, in a format readable by three-dimensional CAD or three-dimensional review system, and outputs the data in response to an output instruction from interface unit

Three-dimensional data generation device, method and program thereof

An optimum route searching apparatus, method and recording medium make it possible to obtain the optimum cable laying route in a short period of time. The optimum route searching apparatus includes an external storage device for storing search data comprising information related to a route that has a node as a connection point; a simplification device for creating simplified data by extracting information related to a node constituting a branching point, a bending point and a terminal point; a connection information creation device for creating a connection information file of cable laying route based on the simplified data; and a searching device for searching for an optimum cable laying route candidate based on the connection information file. The search termination determination determines search termination for all routes in accordance with the route of interconnected nodes from the start point to either the end point or the dead end having been written to all cards by a card writing device.
