2. Description of the Related Art In the drawing work for preparing air conditioning equipment drawings and sanitary equipment drawings, members such as valves and dampers provided on pipes such as pipes and ducts are used to determine how the pipes are accommodated and the path of the pipes. The installation position is frequently changed due to a change or the like. Conventionally, when the position of a member such as a valve or a damper is moved by a CAD system, it is necessary to delete a drawn straight pipe, a valve, and the like and to draw again. In addition, since the fitting state of the pipeline and the like cannot be determined until the drawing is performed again, the drawing must be performed many times when the valve or the like is moved. Further, when the diameter of the moving pipe such as a valve or a damper is different from the diameter of the moving pipe, the operator must relocate the pipe in consideration of a valve suitable for the diameter of the pipe. In some cases, an operation of changing the type of the member was also required. As described above, conventionally, when a member is moved, it is necessary to redraw the drawing, and the member cannot be moved efficiently. Further, the operation of changing the size and the type of the member according to the attribute of the pipe such as the pipe diameter after the member is moved is also a factor that makes it impossible to move the member efficiently. Had become.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing a hardware configuration of a member moving device for implementing the member moving method of the present invention. The member moving device is a CPU (central processing unit) 1
0, keyboard 11 (input device), mouse 12 (input device), color display 13 (display device), printer 14 (output device), scanner 15 (input device), F / D
It comprises a drive 16 (input / output device), a storage device 17 and the like. Each device is connected by a bus 18. The storage device 17 stores a CAD program and the like.

Next, a member moving process for moving a member such as a valve or a damper provided on a pipe such as a pipe or a duct on the pipe will be described with reference to a flowchart shown in FIG. First, a member to be moved is selected from members provided on the pipeline (step A1). The member to be moved is selected, for example, by clicking a mouse click button while pointing a part of the member displayed on the screen with the cursor. Here, when a member other than the movable member is selected, a warning, a display, and the like are performed. The movable members include, for example, (1) straight pipes such as valves, strainers, and dampers (group 1).
One having two connection ports having the same pipe diameter and no other connection ports and having a function of controlling the flow of fluid in a straight pipe. (2) Reducers, hoppers, etc. (Group 2) Of two straight pipes having different connection diameters and having no other connection ports, and having a function of changing the diameter of the straight pipe;
(3) One having at least one connecting port in addition to two connecting ports of a straight pipe, such as a cheese, a cloth, etc. (group 3), having a function of forming a branch path; ) Some of them have a plurality of connection ports such as S-cab, run-out duct, etc. (group 4), each connection port has a parallel vector, and change the flow direction of the fluid in the straight pipe. .

Next, it is determined whether or not the selected member is an elbow (step A2). If the selected member is not an elbow, the process proceeds to step A8. If the selected member is an elbow, it is determined whether the selected member is a movable elbow (step A3). A movable elbow is determined by the selected elbow satisfying the condition (1) or the condition (2). Condition (1): One connection port (first connection port) of the selected elbow is provided in the vertical direction. For example, in FIG. 11, when a 90-degree elbow A is selected on the XY plane,
The second connection port is provided parallel to the XY plane,
Since the first connection port is provided in the Z-axis direction that is perpendicular to the XY plane, the condition (1) is satisfied. Condition (2): The selected elbow has a vertical component in the coordinate component of one connection port (first connection port) and the other connection port (second connection port)
Has no vertical component in the coordinate component. For example,
In FIG. 11, when the 90-degree elbow A is selected on the XY plane, the Z-axis component of the coordinates of the first connection port is changed to the second connection port (the coordinate component is displayed on the XY plane). (No vertical component) is different from the Z-axis component of the coordinates, so condition (2)
Meets.

If it is not a movable elbow, a warning is displayed (step A4), and if it is a movable elbow, it is determined whether there is a paired elbow (step A5). That is, members are sequentially searched from the selected elbow in the direction of the first connection port, and the elbow searched first is set as a paired elbow. For example, in FIG. 11, a search is sequentially performed from the selected 90-degree elbow A toward the first connection port, and the 90-degree elbow B is recognized as a paired elbow. In addition, among the connection ports of the pair of elbows, the connection port on the first connection port side of the selected elbow is the first connection port, and the connection port on the other side is the second connection port. If there is no paired elbow, a warning is displayed (step A4). If there is a paired elbow, it is determined whether or not the second connection ports are three-dimensionally parallel (step A6). That is, it is determined whether or not the vector of the selected elbow and the second connection port of the paired elbow are vectors in the same direction. Second
If the connection ports are not three-dimensionally parallel, a warning is displayed (step A4), and if the second connection ports are three-dimensionally parallel, the selected elbow and the elbow paired with each other are displayed. Is recognized as one member, and is set as the selected member (step A7). For example, in FIG. 11, the vector of the selected second connection port of the 90-degree elbow A and the vector of the second connection port of the paired 90-degree elbow B are vectors in the same direction. The straight pipe C and the 90-degree elbow B are recognized as selected members.

Next, a movement reference point is designated by a cursor and input (step A8). If a part of the member is designated by the cursor to select a member in step A1, step A8 can be omitted if the designated point is recognized as a movement reference point. Next, the amount of movement of the cursor that moves on the screen following the movement of the mouse or the like is determined from the movement reference point, and the members selected based on the amount of movement are held in a connection relationship with the pipeline. While moving on the straight pipe, the moving state is temporarily displayed on the screen (step A9). Here, when the selected member comes into contact with another member on the pipeline, whether or not to move the selected member over the other member based on the combination of the selected member and the other member is determined. Is determined (step A10). For example,
When the selected member and the other member are members of the same group, when the other member is a member of group 1, the other member is a member (elbow) other than the members of groups 1-4. except for)
If the moving member is a member of the group 4 and the other member is an elbow, the moving member is prevented from moving beyond the other member. Next, a designated point of a movement destination for moving the selected member is input (step A11). The designated point of the movement destination is input by, for example, clicking a mouse click button in a state where the designated point of the movement destination is designated by the cursor. Next, the selected member is drawn at the position of the designated point of the movement destination and is confirmed and displayed (step A12). By pressing a mouse click button while selecting a part of the member with the cursor, the member is selected, and by moving the mouse with the click button pressed, the moving state of the selected member is continuously changed. It is also possible to temporarily display the selected member at the cursor position when the press of the click button is released.

The moving process of the member in step A9 in FIG.
This will be described in detail with reference to the flowchart shown in FIG. First, the straight pipe connected to the selected member is recognized (step B1). Next, of the movement amount of the mouse or the like, that is, the movement amount of the cursor displayed on the screen from the movement reference point, the vector component of the vector component parallel to the straight pipe connected to the selected member. The movement amount a is calculated (step B2). Here, the moving direction of the mouse, that is, the cursor on the screen is free, but the members such as the valve and the damper can move only on the straight pipe. The amount component is detected and used as the movement amount of the member.
The method of calculating the movement amount of the member is not limited to this,
For example, the distance between the movement reference point and the cursor may be calculated. Next, the selected member is moved by the movement amount a, and the straight pipe connected to the selected member is expanded and contracted by the movement amount a (step B3). The moving process of the selected member and the expanding / contracting process of the straight pipeline are repeated while the mouse is moved.

Next, referring to FIGS. 4 to 10, a straight pipe A, a straight pipe B, and a straight pipe C such as pipes are arranged, and a member 1 such as a valve is provided between the straight pipe A and the straight pipe B. A process for moving the member 1 in an air-conditioning / water supply / drainage drawing in which a member 2 such as a reducer for changing the diameter of the straight tube is provided between the straight tube B and the straight tube C will be specifically described. . First, a member 1 to be moved is selected on the screen according to a cursor instruction or the like (FIG. 4).
Next, a movement reference point for calculating the movement amount is input (FIG. 5). This movement reference point may be at any position on the screen. Further, the designated point for selecting the member 1 may be set as the movement reference point. Next, of the movement amount of the mouse, that is, the movement amount of the cursor displayed on the screen from the movement reference point,
The movement amount a of the vector component parallel to the straight pipes A and B connected to the member 1 is calculated, and the member 1 is moved by the movement amount a in the moving direction of the mouse, and the straight pipe A is extended by the movement amount a. Then, the straight pipe B is contracted by the moving distance a (FIG. 6).

When the length of the straight pipe B reaches the minimum value e1 of the telescopic straight pipe B due to the movement of the member 1 due to the movement of the cursor, the moving amount a becomes the telescopic straight pipe of the straight pipe B. Minimum value e1,
Length L (L = e1 + L2 + e) obtained by adding the length L2 of the member 2, the minimum value e2 of the straight tube C, and the length L1 of the member 1.
2 + L1), the movement of the member 1 is stopped (FIG. 7).
a). The minimum value of the expansion and contraction straight pipe is considered to be that a pipe and a joint such as a reducer are rarely directly connected to each other in a pipe, and that a straight pipe is generally required between the joints. Things. However, the minimum value of the telescopic straight pipe may be zero. The minimum value of the telescopic straight pipe can be set for each diameter of the straight pipe or can be set arbitrarily. And
When the movement amount a reaches L, the member 1 is moved to the minimum value e2
Is jumped to the opposite side of the member 2 with the straight pipe C being interposed therebetween, and the straight pipe B and the straight pipe A are connected, that is, the member 1 is moved beyond the member 2 (FIG. 7B). When moving in the opposite direction, it is moved in the same manner. At this time,
When the attributes of the straight pipes A and B and the straight pipe C, for example, the pipe diameters are different, the size of the member 1 is changed according to the pipe diameter of the destination straight pipe C (FIG. 7c). In FIG. 7, the process of moving the member 1 onto the straight pipe C is performed using the length of the member 1 having a size corresponding to the diameter of the straight pipes A and B before the movement as L1. The size of the member 1 is changed according to the pipe diameter of the straight pipe C. However, when such processing is performed, when the size of the member 1 is changed, the movement amount a and the straight pipe of the member 1 are changed. It is necessary to correct so that the arrangement position on C corresponds. On the other hand, if the length of the member 1 having the size corresponding to the diameter of the straight pipe C at the movement destination is used as L1, the process of moving the member 1 onto the straight pipe C and changing the size of the member 1 are performed simultaneously. In addition, it is not necessary to correct the correspondence between the movement amount a and the arrangement position of the member 1 on the straight pipe C.

Next, a designated point to which the member 1 is moved is specified (FIG. 8). When the designated point of the movement destination is designated, the member 1 is drawn at the designated point and is confirmed and displayed (FIG. 9). Note that the display method of the member 1 until the designated point of the movement destination is designated may be the same as the display method of the member 1 when the designated point is designated. It is preferable to change the line type, color, etc.

In the above embodiment, the function of changing the size of the selected member in accordance with the attribute of the destination pipe is provided. However, the type of the member may be changed according to the attribute of the pipeline. For example, if the pipe diameter is 100A
If it is less than 100A, a gate valve is used, and if it is 100A or more, a butterfly valve may be used. Therefore, a function is provided for changing the type of the selected member in accordance with the attribute of the destination pipeline. This embodiment will be described in detail with reference to FIG. In addition, in FIG. 10, the straight pipe B and the minimum straight pipe e2 of the telescopic straight pipe minimum value e1 shown in FIG.
The illustration of the straight pipe C is omitted. In addition, the pipe diameter of the straight pipe A is 120A, the pipe diameter of the straight pipe C is 60A, and if the pipe diameter is 100A or more, a rose-fly valve is used. If the pipe diameter is less than 100A, a gate valve is used. I do. A member 1 such as a valve, in this case, a butterfly valve BV provided on a straight pipe A having a diameter of 120A is selected, and the member 1 is moved by instructing a movement amount a with a mouse or the like (FIG. 10a). When the member 1 comes into contact with the member 2,
The member 1 is moved to the straight pipe C side beyond the member 2 by a method similar to the method described with reference to FIG. 7 (FIG. 10B). Here, since the pipe diameter of the destination straight pipe C is 60A, the size of the member 1 is changed (FIG. 10c). Further, if the pipe diameter is less than 100A, a gate valve is to be used, so the member 1 (butterfly valve BV) is changed to the member 3 (gate valve GV) (FIG. 10c).

In the above embodiment, a case was described in which a member such as a valve or a damper which can move only on a straight pipe was selected. However, a member other than the valve and the damper, for example, FIG.
Can be selected. In this case, the 90 ° elbow A, the straight pipe C, and the 90 ° elbow B are recognized as selected members, and the moving process is performed by expanding and contracting the straight pipe A and the straight pipe B according to the amount of movement of the mouse. .

In the above-described embodiment, the present invention is applied to a drawing in which a valve or the like is represented by a single-line member (a figure in which the shape of the member is symbolized or simplified). The present invention can also be applied to a drawing represented by a graphic figure as it is.

It is to be noted that the present invention allows a computer to recognize a member selected from members provided on a pipeline, recognize a designated member movement amount, and The medium can be configured as a medium in which a member movement program for moving on the pipeline while maintaining the connection relationship with the pipeline according to the amount of member movement is recorded.
