The storage unit 20 stores a database that stores necessary conditions of each component in correspondence with the design conditions of the workpiece.

The graphic information storage means 20c stores two-dimensional graphic information (including plane graphic information and cross-sectional graphic information) and three-dimensional graphic information associated with each part. The form of the graphic information may be a single line shape diagram, a double line shape diagram, or a parametric figure. 5A is an example of a single-line shape diagram of the plane of the toilet bowl, FIG. 5B is an example of a double-line shape diagram of the plane of the toilet bowl, and FIG. 5C is a double-line diagram of a cross section of the toilet bowl. FIG. 5D is an example of three-dimensional graphic information of a toilet.

The function of the storage unit 20 can be realized by hardware such as an optical disk (CD, DVD), a magneto-optical disk (MO), a magnetic disk, a hard disk, a magnetic tape, or a memory (ROM, RAM). When the function of the storage unit 20 is realized by a RAM, it is necessary to read the information from an information storage medium storing attribute information and design conditions when the power is turned on.

In this case, the connected part is a duct. The connection target part has at least one connection point connected to the corresponding connected target part.

The display control unit 30b controls the display unit 10 to display the drawing information (for example, the connection target unit instructed to draw by the drawing command unit) of the component of the workpiece.

The connection point determination unit 30 c determines one connection point among the connection points of the connected target parts displayed on the display unit 10. A method of determining the connection point by the connection point determination unit 30c will be described in the later-described processing flow.

Based on the connection point determined by the connection point determination unit 30c, the connection condition extraction unit 30d extracts the type and necessary condition of the connection target part connected to the connection point from the attribute information corresponding to the connection target part. Is. Moreover, as a necessary condition of a connection object part, a dimension (a diameter, when a connection object part is piping) etc. can be mentioned, for example.

The starting means 30e is for starting the drawing command means 30a for instructing the drawing of the connection target part that satisfies the type of the connection target part extracted by the connection condition extraction means 30d and the necessary conditions. For example, when the connection point to which the water supply pipe is connected is selected by the connection point determining means 30c, the activation means 30e activates the drawing command means 30a for instructing the drawing of the water supply pipe.

The attribute determining unit 30f determines the attribute of the component of the workpiece to be drawn based on the workpiece design condition stored in the design condition storage unit 20b. Specifically, when the project condition that the building is a reinforced concrete building has been set as the design condition of the workpiece, the attribute determination means is configured according to the project information when drawing various components. Determine attribute information such as element type.

The graphic information generating means 30g generates two-dimensional graphic information (including plane graphic information and cross-sectional graphic information) and three-dimensional graphic information. Specifically, the graphic information generating unit 30g generates graphic information (for example, parametric graphic) according to the dimensions of the constituent elements included in the attribute information (see FIG. 6). By creating graphic information (parametric drawing) based on the dimensions included in the attribute information, the graphic information stored in the storage unit 20 can be reduced accordingly. FIG. 7 is an example of a three-dimensional parametric figure of a panel tank. This figure is input by inputting the number of horizontal panels, the number of vertical panels, and the number of panel stages, and reading the dimensions of each panel from the attribute information and performing calculation processing. Can be generated.

The graphic information extracting unit 30h extracts two-dimensional graphic information (planar graphic information, cross-sectional graphic information) or three-dimensional graphic information of a part from the graphic information storage unit 20c.

The position recognizing means 30 i is a means for recognizing the position (design position) of the graphic information of the two-dimensional or three-dimensional part displayed on the display unit 10. The position recognition means 30i can calculate based on the distance from the reference point on the screen, for example.

The component designation unit 40b is a unit that designates graphic information of a two-dimensional or three-dimensional component displayed on the display unit 10. When the graphic information of a plurality of parts is displayed on the display unit 10, the cursor is moved with the mouse, and the graphic information is designated by clicking, the mouse functions as a part designating means.

The design condition input means 40c is a means for inputting the design conditions of the workpiece.

The connection area designating unit 40d is a unit for the operator to designate a connection target part and a connection point. For example, the connection area can be specified by moving the cursor displayed on the screen with the mouse as the connection area specifying means 40d and clicking the mouse when the cursor is in a predetermined area.

The route editing means 40e is a means for inputting change information of a route such as piping displayed on the display unit 10. For example, the route of the component displayed on the display unit 10 can be changed by the route editing means 40e by pressing a predetermined key on the keyboard.

2. Operation (1) First Operation Example Description will be given with reference to FIGS. 9 to 11, taking a toilet as an example of a connection target part and a drain pipe as an example of a connection target part.

First, the parts to be connected to be displayed on the display unit 10 are designated by the component designation unit 40b (S10). When the part to be connected is specified by the component specifying unit 40b, the display control unit 30b displays the part to be connected 70 on the display unit 10 (see S11, FIG. 9A).

Next, a connection area is designated by the connection area designation means 40d (S12, see FIG. 9B). This connection area can be specified by moving the cursor 76 with a mouse and clicking the mouse, for example. When the connection region is designated, the connection point determination unit 30c determines the connection point 72. For example, there are two methods for determining the connection point. First, as shown in FIG. 10, distances X1 and Y1 from the designated position 80 designated by the connection area designating means 30c to each connection point are calculated, the nearest connection point 72 is determined, and the connection point is determined. In this method, 72 is a connection point to which the connection target unit is connected. Secondly, as shown in FIG. 11, selection areas 72a and 78a are determined for each connection point 72 and 78, and it is determined which selection area the specified position 80 specified by the connection area specifying means 40d is in. In this method, the connection point 72 in the selection area 72a is determined as the connection point to which the connection target unit is connected.

Next, the connection condition extraction unit 30d reads the connection condition from the attribute information of the connected target unit based on the determined connection point (S14). Next, the starting means 30e automatically starts the drawing command means 30a for instructing the drawing of the connection target part satisfying the type of the connection target part included in the connection condition and the necessary conditions. For example, when the connected target portion is a toilet, a plotting command means for commanding plotting of a water supply pipe or a drain pipe is activated (S15). Here, since the connection point 72 is selected, the drawing command means 30a for the drain pipe is automatically activated.

Next, the route of the connection target unit is displayed on the display unit 10 in association with the route information input by the route input unit 40a. Specifically, by moving the cursor 76 with the mouse, the drain pipe 74 having a path corresponding to the movement path of the cursor 76 can be displayed on the display unit 10 (see S16, FIG. 9C).

(2) Second Operation Example An example of connecting a pipe as a connection target part to a pipe as a connection target part will be described.

Basically, it is the same as the first operation example, but as shown in FIG. 12 (A), the pipe to be connected has a plurality of connection points 72 (1), 72 (2)... 72 (n ). In the case where another pipe 92 is connected to the pipe 90, for example, it can be performed as follows. For example, as shown in FIG. 12A, the connection point 72 (m) is determined by the connection point determination means 30c when the cursor 76 is brought to the region to be connected with the mouse and clicked there. The connection condition extraction unit 30d reads the connection condition corresponding to the connection point 72 (m) from the attribute information, and automatically starts the drawing command unit 30a for drawing the pipe 76 that satisfies the connection condition. Then, a route is input by the route input means 40a, and based on the input information, the display control means 30b displays other piping on the display unit 10 as shown in FIG.

(3) Third Operation Example A third operation example will be described with reference to FIG.

A component of the workpiece is specified by the component specifying means 40b (S20). When the component of the workpiece is specified by the component specifying means 40b, the attribute determining means 30f determines the attribute of the component according to the design condition (project information) of the workpiece stored in the design condition storage means 20b. (S21). Next, the display control means 30b displays the constituent elements that satisfy the determined attribute on the display unit 10 (S22).

(4) Fourth Operation Example A fourth operation example will be described with reference to FIG. In this operation example, an operation example for displaying the components of the workpiece (including the connection target part and the connection target part) will be described.

When displaying the components of the working part, planar graphic information, cross-sectional graphic information, and three-dimensional graphic information may be displayed. Specifically, two-dimensional and three-dimensional graphic information can be displayed as follows. Here, an example of designing with plan view data as an axis will be described.

First, a part is displayed in the plane data area (S30). The position recognition means 30i recognizes the position of the component displayed in the plane data area on the display unit 10 (S31). Next, the position changing means 30j changes the position information of the attribute information of the part to the position information of the graphic information of the part recognized by the position recognition means 30i (S32). Next, the display control unit 30b acquires position information from the attribute information of the component, and displays the corresponding cross-sectional graphic information and three-dimensional graphic information at the position corresponding to the position of the two-dimensional graphic information. And displayed in each of the three-dimensional data areas (S33).

Here, an example is given in which the plan view data is designed as an axis. However, the design may be performed using cross-sectional view graphic data or three-dimensional graphic data as an axis.

The graphic displayed in any of the above operation examples may be a graphic generated by the graphic information generating means 30g or a graphic extracted by the graphic information extracting means 30h.

3. Effects (1) Conventionally, when drawing the connection target part connected to the connection target part, the type of the connection target part, the position of the connection point, the mounting height, and the like are input for drawing. However, according to this embodiment, the connection point determination unit 30c determines a connection point based on information designated by the operator (for example, the position specified by the cursor), and the connection condition extraction unit 30d corresponds to the connection point. The connection condition (type of connection target part and necessary condition) is read from the attribute information, and the starting means 30e automatically starts the drawing command means 30a for instructing the drawing of the connection target part satisfying the type and necessary condition of the connection target part. ing. Therefore, according to this embodiment, since there is no need to start a command for inputting the type of the connection target part, the position of the connection point, etc. or a process for inputting such information, the number of drawing work steps is reduced. This can greatly reduce the efficiency of drawing work.

Further, until now, special work such as input work has been required to execute the drawing command means, but according to this embodiment, if the operator designates a position close to the connection point, it is automatically performed. Since the drawing command means 30a is automatically activated, it is possible to draw with a simpler operation method. Therefore, even a person who is not skilled in a drawing system such as CAD can operate more easily.

In addition, once the connection condition is input to the attribute information, it is not necessary to input the information at the time of connection. Therefore, it is possible to reduce errors in creating the design drawing based on the information input error.

In addition, this embodiment is particularly useful as a design drawing creation system for buildings with many connection processes.

(2) Moreover, according to this embodiment, since the attribute determination means 30f and the design condition memory | storage part 20b are included, there can exist the following effect.

The attribute determining means 30f reads the design conditions from the design condition storage means 20b, and determines the attributes (for example, type and mounting position) of the components of the workpiece to be drawn according to the design conditions. When drawing an element, it is not necessary to input attribute information. For this reason, the efficiency of drawing can be improved.

(3) According to this embodiment, it is possible to display plan view data, cross-sectional view data, and three-dimensional data on the screen when creating a design drawing. Thereby, when designing, the created design drawing can be checked simultaneously from various viewpoints.

The present invention is not limited to the above embodiment, and various modifications can be made without departing from the gist of the present invention.

In the above example, an example in which each component has a plurality of connection points has been described. However, the present invention includes an aspect in which the connection target portion is connected to a component having only one connection point.

It can be applied when designing a workpiece, for example a building.
