(For example, the CPU 8 in FIG. 2).

FIG. 1 shows an external configuration of a building equipment CAD system to which the present invention is applied. As shown in the figure,
In this system, a display 2 for displaying a drawing and a tablet 3 for inputting with a pen 1 are integrally configured. When the user touches the tablet 3 with the pen 1, the tablet 3 detects the position (contact coordinates). The pen 1 is provided with a switch 12, and when the user presses the switch 12, a predetermined command is input to the CPU 8 (FIG. 2) in the main body 11. The tablet 3 is formed of a transparent member, and allows a user to visually recognize an image displayed on the display 2 disposed thereunder.

The main body 11 contains an interface 4, a hard disk 5, a CPU 8, a ROM 9, a RAM 10, and the like, which will be described later with reference to FIG. The keyboard 6, the display 2, the tablet 3, and the plotter 7 are connected to the main body 11.

FIG. 2 shows the electrical configuration of the system shown in FIG. The CPU 8 executes various processes according to a program stored in the ROM 9. The RAM 10 appropriately stores data, programs, and the like necessary for the CPU 8 to execute various processes.
A pen 1, a display 2, a tablet 3, a hard disk 5, a keyboard 6, and a plotter 7 are connected to the interface 4, and the interface 4 executes interface processing between these devices and the CPU 8. ing.

Accordingly, a key signal input by the user operating the keyboard 6, or coordinate data input from the tablet 3 by the user operating the pen 1,

Reference numeral 8 controls the display 2 via the interface 4 to display a predetermined figure. The CPU 8 controls the plotter 7 via the interface 4 so that the drawing created by the user is plotted on paper or the like.

FIG. 3 shows functional blocks substantially formed inside by the CPU 8 executing the program. The coordinate input unit 13 performs a process for the user to input coordinates using the pen 1. For example, coordinates at which a predetermined process is to be executed are input here.

The processing target graphic search section 14 performs processing for searching for a graphic (symbol) to be subjected to a predetermined processing. The processing determination unit 15 determines whether or not a predetermined process can be performed using the searched graphics, and if it is determined that the predetermined processing can be performed, the coordinates input by the coordinate input unit 13 indicate the processing target graphic. A predetermined process is performed on the graphic searched by the search unit 14.

Next, referring to FIG.
The operation in the case of performing symbol connection processing in the system will be described. When this system is started, CPU8
Is, for example, as shown in FIG.
1 causes the display 2 to display a screen arranged at a predetermined position. Also in this display example, the user selects the elbow symbol selection button 101-1 and displays the elbow graphic 30.
A is displayed.

In this state, when connecting the straight pipe to the elbow, first, in step S11, the user selects the straight pipe symbol selection button 101-2 shown in FIG. Subsequently, in step S12, it is determined whether or not the currently selected object is a pipe or a duct among general, skeleton, drafting, pipe, and duct. When it is determined that the selected object is not a pipe or a duct, the process proceeds to step S13, and other processing is performed. When it is determined that the selected object is a pipe or a duct, the process proceeds to step S14.

In step S14, the coordinate input unit 13
Thus, it is determined whether or not the pen 1 has touched the tablet 3. When it is determined that the pen 1 is not in contact with the tablet 3, the process returns to step S14. If it is determined in step S14 that the pen 1 has touched the tablet 3, the coordinate input unit 13 detects the contact coordinates in step S15.

In step S16, as shown in FIG. 5, the contact coordinates detected by the coordinate input unit 13 have an aperture 20 having a predetermined distance range around the contact coordinates.
Is displayed. Subsequently, in step S17, the processing target graphic search unit 14 determines whether or not the connection points of the graphics already displayed (the connection points 40A and 40B of the elbow graphic 30A in this case) exist in the aperture 20. Is determined. Connection points 40A, 40 in aperture 20
If it is determined that B does not exist, in step S18, the processing target graphic search unit 14 deletes the mark 50A if it is displayed, and does not do anything if the mark 50A is not displayed. It returns to S14. In step S17, the connection point 40 is set in the aperture 20.
If it is determined that A and 40B exist, step S1
Then, as shown in FIG. 6, a mark 50A indicating that connection processing is possible is displayed. In this display example,
The character “continuation” is the mark 50A. Thereby, the user can easily recognize that the connection processing is possible.

In step S20, the processing determining unit 15
Thus, it is determined whether or not the switch 12 of the pen 1 has been pressed. If it is determined that the switch 12 of the pen 1 has not been pressed, the process returns to step S14. If it is determined that the switch 12 of the pen 1 has been pressed, the process proceeds to step S21. In step S21, the processing determination unit 15
The height, diameter, and the like of the straight pipe that match the height, diameter, and the like of the already displayed elbow graphic 30A are calculated. Subsequently, in step S22, the processing determination unit 15
As shown in FIG. 7, a straight pipe figure 30B is displayed on the display 2 while being connected to the elbow figure 30A.

Thus, the symbol connection process is performed. Note that the mark 50A may be changed in color or blinking.

FIG. 8 shows the construction equipment CAD system.
It is a flowchart explaining the operation of symbol insertion processing. The processing of steps S41 to S46 is processing corresponding to the processing of steps S11 to S16 shown in FIG. 4, and thus the description thereof is omitted. Here, in step S41, the symbol selection button 101-3 is operated.
It is assumed that a valve is selected as a symbol to be inserted. In step S47, the processing target graphic search unit 14
Accordingly, it is determined whether or not there is a graphic into which a valve can be inserted in the aperture 20. If it is determined that there is no figure in the aperture 20 into which a valve can be inserted, the process proceeds to step S48. If the mark 50B is displayed, it is deleted and the process returns to step S44. In step S47, when it is determined that there is a figure into which the valve can be inserted in the aperture 20, the process proceeds to step S49, and the processing determination unit 15 sets the mark 50B indicating that the insertion processing is possible as shown in FIG. And so on. In this display example, the character “up” is the mark 50B.

In step S50, the processing determining unit 15
Thus, it is determined whether or not the switch 12 of the pen 1 has been pressed. If it is determined that the switch 12 of the pen 1 has not been pressed, the process returns to step S44. If it is determined that the switch 12 of the pen 1 has been pressed, the process proceeds to step S51. In step S51, the processing determination unit 15
The diameter of the valve conforming to the straight pipe figure 30B is calculated. Subsequently, in step S52, the processing determination unit 15
As shown in FIG. 10, the valve graphic 30 </ b> C is displayed on the display 2 while being inserted into the straight pipe graphic 30 </ b> B.

In this manner, the symbol insertion processing is performed. Note that the mark 50B may be configured by a change in color or blinking as in the case of the mark 50A described above.

As described above, in the state where a predetermined point of a symbol exists in the aperture 20, the mark 50A or 50B indicating that connection or insertion processing is possible is displayed. It is not necessary to move the pen 1 much
Operation efficiency is improved.

In the above description, the process of connecting and inserting pipes has been described. However, this process can also be applied to the case where a drawing of a duct or the like is created. The present invention can also be applied to a case where processing other than connection and insertion is performed.

The program for performing each of the above-described processes is provided to the user by recording it on a recording medium such as a magnetic disk or a CD-ROM, or provided to the user via a network or the like. You may make it record on a recording medium.
