2. Description of the Related Art When using a CAD system, C
It is not uncommon for drawing data created by an AD system to write a plurality of dimensions for the same origin, that is, progressive dimensions whose dimension values progressively increase with respect to the origin. In a conventional CAD system, when automatically creating a progressive dimension, simply input the origin at which the progressive dimension is to be created, a plurality of measurement points, and dimension value positions, and automatically enter the progressive dimension for each measurement point. It just created. For this reason, in the conventional CAD system, if you want to write a progressive dimension for the same origin in addition to the previously created progressive dimension, repeat the operation of creating the progressive dimension again from the beginning to create the additional progressive dimension. I was trying to do it.

[0003]

As described above, in the conventional CAD system, when creating a progressive dimension, an origin at which the progressive dimension is to be created, a plurality of measurement points and dimension value positions are input. If you want to automatically create the progressive dimensions for each measurement point, add them to the previously created progressive dimensions, and write the progressive dimensions for the same origin,
The operation of creating a progressive dimension was repeated again from the beginning to create an additional progressive dimension. In addition, when the dimension values are arranged corresponding to the positions of the measurement points of the progressive dimensions, and the dimension values interfere with each other due to overlapping, etc., the positions of the dimension values are shifted so as not to interfere. For this reason, the created progressive dimensions are often unsightly due to irregularities in the dimension value positions and shifts.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and it is possible to easily and appropriately correct the shift state of a progressive dimension with a simple operation for an already created progressive dimension. It is an object of the present invention to provide a progressive dimension correcting method and apparatus which can remarkably reduce the burden of the operation of the above.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a schematic configuration of a CAD system in which a progressive dimension correcting device according to one embodiment of the present invention is incorporated. In the CAD system of the present embodiment, when correcting the progressive dimensions entered on the drawing data, the progressive dimension elements to be corrected among the already entered progressive dimensions, the reference data for shift correction, and if necessary, By specifying the shift amount, the progressive dimension on the displayed and stored drawing data is re-shifted by a predetermined shift amount on the basis of the reference data, the progressive dimension element to be corrected based on the instruction. Can be rewritten to progressive dimensions.
In this embodiment, not only the shift amount correction but also the decimal point position correction of the dimension value of the progressive dimension can be performed.

The CAD system shown in FIG. 1 includes a CAD processing section 1, an input device 2, a display 3, an output device 4, and a storage device 5. CAD processing unit 1 includes a CPU
(Central processing unit) (not shown), and executes CAD processing including progressive dimension correction processing such as shift amount correction and decimal point position correction. The input device 2 includes an operation input device such as a keyboard and a pointing device such as a mouse.
Other external information required for processing is input to the CAD processing unit 1. The display 3 displays necessary information such as image information processed by the CAD processing unit 1 and information related to input by the input device 2. The output device 4 includes a plotter, a printer, or the like, and outputs image data processed by the CAD processing unit 1 as a hard copy. The storage device 5 is composed of a disk device such as a hard disk device, for example.
It operates in association with the D processing unit 1 and stores data such as image information before processing, after processing, and during processing as needed.

In this case, the CAD processing unit 1
In addition to the configuration for performing the D processing, the display control unit 1 for performing the progressive dimension correction processing according to the embodiment of the present invention.
1, a command input unit 12, an element designation unit 13, a reference data instruction unit 14, a shift amount input unit 15, a memory 16, and a rewrite control unit 17.

The display control section 11 controls the display on the display 3. Under the control of the display control unit 11, drawing data and the like are displayed on the screen of the display 3. The command input unit 12 performs a process for allowing an operator to input a command for correcting a progressive dimension, that is, a command including a shift amount correction command and a decimal point correction command, for example, by interactive operation with the screen of the display 3. For this reason, the command input unit 12 controls the display control unit 11 as needed. When the shift amount correction command is input from the command input unit 12, the system enters a “shift amount correction mode”, and when the decimal point correction command is input, the system enters a “decimal point position correction mode”.

For example, in the "shift amount correction mode", the element designating unit 13 performs a process for allowing an operator to designate a progressive dimension element to be subjected to shift amount correction,
In the "decimal point position correction mode", a process is performed for allowing the operator to specify a progressive dimension element to be subjected to decimal point position correction. For this reason, the element specifying unit 13 works with the command input unit 12 and controls the display control unit 11 as necessary.

In the "shift amount correction mode", the reference data instructing section 14 performs a process for instructing the operator to specify progressive dimension data as a reference for the shift amount correction, and in the "decimal point position correction mode", A process is performed to allow the operator to specify dimension value data of a progressive dimension as a reference for position correction. Therefore, the reference data instruction unit 14 also controls the display control unit 11 as needed. The shift amount input unit 15 functions in the “shift amount correction mode”, and performs a process for inputting and setting a shift amount for shift amount correction by an operator. For this reason, the shift amount input unit 15 is also provided with the display control unit 1 as necessary.
Control 1

The memory 16 stores information including CAD drawing data to be displayed by the display control unit 11. The contents stored in the memory 16 are transferred to the storage device 5 as needed. The memory 16 may share a memory used in normal CAD processing in the CAD processing unit 1.

In the "shift amount correction mode", the rewrite control unit 17 sets the entire progressive dimension element group specified by the element specifying unit 13 on the basis of the reference data specified by the reference data specifying unit 14. Shift input unit 1
The rearrangement is performed according to the shift amount input by 5 and the progressive dimension of the drawing data displayed on the display 3 and stored in the memory 16 is rewritten as necessary. Further, in the “decimal point position correction mode”, the rewriting control section 17 determines the progressive dimension specified by the element specifying section 13 with reference to the decimal point position of the dimension value of the reference data specified by the reference data specifying section 14. The dimension values of the entire element group are rearranged so that the decimal point positions are aligned, and the progressive dimensions of the drawing data displayed on the display 3 and stored in the memory 16 are rewritten as necessary.

Next, the operation related to the correction of the progressive dimensions in the CAD system having such a configuration will be described in detail with reference to the flowchart shown in FIG. The process shown in FIG. 2 is started as an interrupt process by a command input during normal drawing or editing operation in the CAD system.

First, the command input unit 1 of the CAD processing unit 1
2, a dimension correction command for a progressive dimension is selected by the operator (step S1), and when the operator indicates which of the "shift amount correction mode" and the "decimal point position correction mode" is the correction mode (step S1). S2), the system determines whether the mode is the "shift amount correction mode" or the "decimal point position correction mode" (step S3).

In step S3, "shift amount correction mode"
Is determined, the system is set to the shift amount correction mode (step S4). In the "shift amount correction mode", a progressive dimension element group on the drawing to be subjected to the shift amount correction is selectively designated (step S5), and the re-shift of the progressive dimension in the designated progressive dimension element group is performed. The dimensional data to be used as a reference is selectively designated (step S6), and the shift amount of the re-shift of the designated progressive dimension element group is input (step S7).

The rewriting control unit 17 executes the above steps S5 to S5.
Based on the information specified or input in S7, the progressive dimension element group specified by the element specifying section 13 is input by the shift amount input section 15 with reference to the reference data specified by the reference data specifying section 14. The rearrangement is performed with the shifted amount and the shift amount is corrected (step S8), and the progressive dimension of the drawing data displayed on the display 3 and stored in the memory 16 is rewritten as necessary (step S9). .

After the rewriting process is performed by the rewriting control section 17 in step S9, it is determined whether or not to end the shift amount correction (step S10). If the shift amount is to be corrected, the process returns to step S5 and returns to steps S5 to S5.
Step 10 is repeated. If it is determined in step S10 that the shift amount correction is to be ended, the system ends the shift amount correction processing and proceeds to the next processing.

If it is determined in step S3 that the mode is the "decimal point position correction mode", the system is set to the decimal point position correction mode (step S11). In the "decimal point position correction mode", a progressive dimension element group on the drawing to be subjected to the decimal point position correction is selectively designated (step S1).
2) Selectively instruct the dimension data to be used as a reference for rearranging the dimension values of the progressive dimensions in the designated progressive dimension element group (step S13).

The rewriting control unit 17 executes the above-described step S12
Based on the information specified in S13 and S13, the dimension values of the progressive dimension element group specified by the element specifying unit 13 are rearranged with reference to the decimal point position of the reference data specified by the reference data specifying unit 14. Then, the dimension value position is corrected (step S14), and the progressive dimension of the drawing data displayed on the display 3 and stored in the memory 16 is rewritten as necessary (step S15).

After the rewriting process is performed by the rewriting control unit 17 in step S15, it is determined whether or not the decimal point position correction is to be terminated (step S16). If the decimal point position is to be corrected, the process returns to step S12, and the processes of steps S12 to S16 are repeated. Step S16
If it is determined that the decimal point position correction is to be ended, the system ends the decimal point position correction processing and shifts to the next processing.

Here, an example of a specific operation in this system will be described in detail. First, as shown in FIG.
In the menu on the editing screen of the AD system,
When "execute" (annotation means an entry of an annotation other than drawing such as a dimension line), a menu as shown in FIG. 4 is displayed. In this menu, "dimension"-"element" Is displayed, a menu as shown in FIG. 5 is further displayed, and a message "Please indicate the type of dimension line" is displayed on the prompt line at the bottom of the screen of the display 3, for example. This requires the operator to indicate the type of dimension line to be entered.

When the user selects "Progression"-"Execute" (meaning the execution of a progressive dimension) in this menu, the mode changes to a progressive dimension creation mode, and a menu as shown in FIG. The display of "Please indicate the type of progressive dimension line" on the line requests the operator to indicate the type of progressive dimension to be entered. When "dimension correction" is selected in this menu, the mode becomes the progressive dimension correction processing mode regardless of the type of the progressive dimension line selected at that time, and a menu as shown in FIG. The message "Please specify the type of correction" is displayed on the upper prompt line, and the operator is requested to select one of the "decimal point position correction mode" and the "shift amount correction mode". You.

Selection and change of these menus are performed by an operator operating a cursor movement key or a mouse of the input device 2 while looking at the editing screen of the display 3 to move a cursor bar on the menu. When the user selects “shift amount correction”-“execute” in the menu of FIG. 7 and selects “shift amount correction mode”, the system enters “shift amount correction mode”, and a menu as shown in FIG. 8 is displayed. You.

In the menu of FIG. 8, in the normal case, “Single”-“Specify” has already been preferentially selected at the time of display as shown in the figure. In this state, as shown in FIG. 8, a message "Please indicate the target element" is displayed on the prompt line, so that the operator is requested to individually specify the progressive dimension element to be subjected to the shift amount correction. Is done. When the first target element is designated by operating the mouse or the like, designation of the next target element is similarly requested, and this is repeated to designate all desired target elements. To end the selection of the target element, select “Single”-“End” as shown in FIG.

When the selection of the target element is completed, a menu as shown in FIG. 10 is displayed with "Execute" selected, and a prompt "On the screen," Please specify the reference element "" is displayed. Is performed, the operator is required to specify a progressive dimension element serving as a reference for shift amount correction.

When the user designates a standard progressive dimension element by operating a mouse or the like, a message "Please enter a shift amount" is displayed on the prompt line on the screen as shown in FIG. Thus, the operator is required to input a shift amount. When the shift amount is input to, for example, “30” (mm) or the like by operating a keyboard or the like, as shown in FIG. 12, the designated target progressive dimension element on the drawing is determined with reference to the designated reference element ( That is, the reference element is not shifted), and the progressive dimension is rewritten by the input shift amount. In this state, the menu and the prompt line prompt the instruction of the target element as shown in the figure, and when the other progressive dimension elements are corrected for the shift amount, the same operation as the above-described operation of the target element is performed again. repeat. To end the shift amount correction, select "Cancel".

Upon completion of the shift amount correction, the screen returns to the correction mode selection screen similar to FIG. 7 as shown in FIG. Next, the "decimal point position correction mode" will be described. For example, when "decimal point position"-"execute" is selected in the menu of FIG. 13, the system enters "decimal point position correction mode", and a menu as shown in FIG. 14 is displayed.

In the menu of FIG. 14, in a normal case,
At the time when it is displayed, "Single"-"Specify" is preferentially selected, and the indication "Please indicate the target element" is displayed on the prompt line, so that the operator can see the decimal point position. It is required to specify the progressive dimension element to be corrected. For example, "Inside fence"-"Specify" is selected, and the target element is enclosed in the instruction frame and "Inside fence"-"Specify" is selected. Thereafter, by selecting "inside the fence"-"end" as shown, the selection of the selected element is ended.

When the selection of the target element is completed, a menu as shown in FIG. 15 is displayed with "execute" selected, and the prompt "On the screen," Please indicate the reference dimensions "" is displayed. Is performed, the operator is required to specify a progressive dimension element that is a reference for decimal point position correction.

By operating a mouse or the like to designate a reference progressive dimension element, as shown in FIG. 16, the dimension value of the designated target progressive dimension element on the drawing is changed to the dimension value of the designated reference element. With respect to the decimal point position (that is, with the decimal point position aligned), the rearrangement is performed and the progressive dimension is rewritten. In this state, the menu and the prompt line prompt the instruction of a further target element as shown in the figure, and when the decimal point position of another progressive dimension element is to be corrected, the same as the above-mentioned instruction of the target element is performed again. Repeat the operation. To end the decimal point correction, select "Cancel". Upon completion of the shift amount correction, the screen returns to the correction mode selection screen having the same menu and prompt line display as in FIG. 13 or FIG.

As described above, the displayed and stored drawings are indicated by designating the progressive dimension elements to be corrected, the reference data for shift correction, and the shift amount as required, of the previously entered progressive dimensions. The progressive dimension on the data can be very easily rewritten based on the instruction to the progressive dimension element to be corrected to the progressive dimension re-shifted by a predetermined shift amount with reference to the reference data. In addition, the decimal point position of the dimension value of the progressive dimension can be extremely easily corrected by performing the same operation as the correction of the shift amount.

In the above description, the shift amount is newly input at the time of the shift amount correction. However, the shift amount at the time of the shift amount correction may be fixedly set in advance. Alternatively, only the shift amount correction may be performed without performing the decimal point position correction. Further, the shift amount correction and the decimal point position correction may be performed simultaneously and collectively.

[0036]

As described above, according to the present invention, a group of progressive dimensions on a drawing to be subjected to shift amount correction is selected and designated, and a shift of the progressive dimension in the designated group of progressive dimensions is performed. The dimension data to be used as a reference is designated, and the data of the designated progressive dimension group is rewritten to the progressive dimension group subjected to a required shift around the designated dimension data. It is possible to provide a method and an apparatus for correcting a progressive dimension that can easily and appropriately correct a shift state of the progressive dimension with a simple operation for a created progressive dimension, and can significantly reduce an operator's operation burden. it can.
