Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable wiring route (hereinafter, simply referred to as "wiring route") drawing input system used in plant construction design of, for example, water treatment facilities and power plant facilities. The present invention relates to a wiring route drawing input method and device applied to CAD data generation for summing the lengths of wiring materials in a three-dimensional wiring route such as a wire cable in a conduit) or a tray.

[0002]

2. Description of the Related Art In recent years, a CAD system has been constructed in which a length of a material to be wired (such as an electric wire cable) is picked up and aggregated with high accuracy in drawing a wiring route in an electric wire cable laying work for plant construction. The wiring route data of the entire plant is created by drawing the wiring route with three-dimensional coordinates.

Then, the wiring route is selected based on the wiring route data of the electric cable and the wiring information (information from which position to which position) and the lengths are totaled.

The wiring path is mainly a plan view C
It is defined by drawing a straight line on the AD screen,
The XY coordinate value of each straight line is determined by the start point position and the end point position. In addition, the Z coordinate is manually input as a numerical value, whereby a three-dimensional coordinate value is generated.

Generally, in a wiring path such as a tray or a pit, the Z coordinates of the start point position and the end point position are often the same, so that the input operation does not require much labor. However, for example, when connecting two parallel wiring paths with different Z coordinates (height) or when inputting a vertical wiring path such as a conduit, change to perspective view display and input the wiring path. There is a need to.

In this case, since the input operation is performed while switching the viewing angle between the plan view display and the perspective view display, a great deal of labor is required and work efficiency is deteriorated.

[0007] For example, the wiring path from the tray to the device is usually intended for a conduit, and the wiring path for such a conduit is composed of a plurality of horizontal and vertical line segment wiring paths. Therefore, the input procedure in this case is
It becomes like (1) to (3) below.

(1) First, one horizontal wiring path is drawn on the plan view display screen. At this point, the Z coordinate value is "0", so Z coordinate values are given to both end points. (2) Subsequently, similarly, one horizontal wiring path is drawn on the flat display screen, but it is difficult to select two overlapping straight lines on the plan display, so after switching the display to perspective view. , Z coordinate values are given to both ends of the drawn wiring path. (3) Finally, while maintaining the display state in a perspective view, a wiring path connecting two parallel wiring paths is drawn.

In the above-mentioned input procedures (1) to (3),
In order to connect a plurality of horizontal wiring paths whose Z coordinates are different from each other by a vertical wiring path, the main body is a plan view display, and a display switching operation frequently occurs. Therefore, there has been a demand for a system with improved workability and improved operability.

[0010]

As described above, the conventional method for inputting the drawing of the wiring route is based on the information input on the CAD for the wiring route and the information about where to connect the cable. Although the route is selected and the length of the cable is picked up, three-dimensional coordinates are handled in the wiring route, and especially in the case of the wiring route from the tray to the equipment, the conduit is the target, so the start-up And many vertical wiring paths including falling edges occur.

Therefore, when inputting a vertical wiring route, a method of inputting coordinate values or displaying in perspective view is used, but in the case of displaying in perspective view,
It is necessary to alternately enter the perspective view display and the plan view display repeatedly, and as a result, there is a problem that a great deal of labor is required for three-dimensional input.

The present invention has been made in order to solve the above problems. The position between two points to be drawn as a wiring route is designated on the CAD, and a plane passing through the designated two points is set as a route cross section. 3D wiring route data is accurately generated by displaying a screen and displaying a plurality of wiring route patterns including two designated points on the screen and designating the wiring route by designating the wiring route to be drawn. An object of the present invention is to obtain a method and apparatus for drawing a wiring route that can be used.
