[0002]

2. Description of the Related Art When using a CAD system, C
It is not uncommon to want to write a plurality of dimensions for the same origin, that is, progressive dimensions in which the dimension value progressively increases with respect to the origin, in the drawing data created by the AD system. In the conventional CAD system, when the progressive dimension is automatically created, simply input the origin, the multiple measurement points and the dimension value position where the progressive dimension should be created, and the progressive dimension for each measurement point is automatically calculated. I just created it. Therefore, in the conventional CAD system, if you want to add to the created progressive dimension and write the progressive dimension for the same origin, repeat the procedure of creating the progressive dimension 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, the origin, the plurality of measuring points, and the dimension value position where the progressive dimension should be created are input. , If you want to automatically create the progressive dimension for each measurement point, add it to the created progressive dimension, and write the progressive dimension for the same origin,
The process of creating the progressive dimension was repeated again from the beginning to create the additional progressive dimension. Further, when the dimension values are arranged corresponding to the positions of the measurement points of the progressive dimension, and when the dimension values overlap with each other or interfere with each other, the positions of the dimension values are shifted so as not to interfere. For this reason, it is not uncommon for the progressive dimensions that are created to be unsightly because the dimension value positions and shifts are not uniform.

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 the progressive dimension to the already created progressive dimension by a simple operation. It is an object of the present invention to provide a progressive dimension correcting method and device which can remarkably reduce the operation load.

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 an embodiment of the present invention is incorporated. In the CAD system according to the present embodiment, in correcting the progressive dimension entered on the drawing data, the progressive dimension element to be modified among the already entered progressive dimensions, the reference data for shift modification, and as necessary. By designating the shift amount, the progressive dimension on the displayed and stored drawing data is re-shifted by the predetermined shift amount based on the designation, based on the standard data, the progressive dimension element to be corrected. It can be rewritten into 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 unit 1, an input device 2, a display 3, an output device 4 and a storage device 5. The CAD processing unit 1 is a CPU
A central processing unit (not shown) is included to execute 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 necessary for processing is input to the CAD processing unit 1. The display 3 displays necessary information such as processed image information 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 the image information processed by the CAD processing unit 1 as a hard copy. The storage device 5 is composed of, for example, a disk device such as a hard disk device, and
It operates in association with the D processing unit 1 to store data such as image information before processing, after processing, and during processing as necessary.

In this case, the CAD processing unit 1 uses the normal CA.
In addition to the configuration for executing the D processing, the display control unit 1 for executing 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 controller 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 the 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 by an interactive operation with the screen of the display 3, for example. Therefore, the command input unit 12 controls the display control unit 11 as necessary. When the shift amount correction command is input by the command input unit 12, the system is in the "shift amount correction mode", and when the decimal point correction command is input, the system is in the "decimal point position correction mode".

In the "shift amount correction mode", for example, the element designating unit 13 performs a process for instructing the operator to indicate the progressive dimension element to be the shift amount correction target,
In the "decimal point position correction mode", a process for causing the operator to designate the progressive dimension element to be the decimal point position correction target is performed. Therefore, the element designating unit 13 works in conjunction 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 carries out a process for allowing the operator to instruct the progressive dimension data as a reference for the shift amount correction, and in the "decimal point position correction mode", the decimal point position correction mode. A process for causing the operator to instruct the dimensional value data of the progressive dimension as the position correction reference is performed. Therefore, the reference data instruction unit 14 also controls the display control unit 11 as necessary. The shift amount input unit 15 functions in the "shift amount correction mode", and performs a process for allowing the operator to input and set the shift amount when correcting the shift amount. For this reason, the shift amount input unit 15 also includes 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 stored contents of the memory 16 are transferred to the storage device 5 as needed. The memory 16 may share the memory used in the normal CAD processing in the CAD processing unit 1.

In the "shift amount correction mode", the rewrite control section 17 uses the reference data instructed by the reference data instructing section 14 as a reference to refer to the entire progressive dimension element group specified by the element specifying section 13. Shift amount input section 1
The rearrangement is performed with 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 rewrite control unit 17 uses the decimal point position of the dimension value of the reference data instructed by the reference data instruction unit 14 as a reference, and the progressive dimension specified by the element designating unit 13 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, with reference to the flow chart shown in FIG. 2, the operation relating to the correction of the progressive dimension in the CAD system having such a structure will be described in detail. It is assumed that the processing shown in FIG. 2 is started as an interrupt processing by a command input during a normal drawing or editing operation in the CAD system.

First, the command input section 1 of the CAD processing section 1
When the operator selects a dimensional correction command for progressive size via 2 (step S1), and the operator instructs either the "shift amount correction mode" or the "decimal point position correction mode" (step S1) (step S1). S2), the system determines whether it is the "shift amount correction mode" or the "decimal point position correction mode" (step S3).

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

The rewrite control unit 17 performs the above-mentioned steps S5 to S5.
Based on the information instructed or input in S7, the progressive dimension element group specified by the element specifying unit 13 is input by the shift amount input unit 15 with reference to the reference data instructed by the reference data instructing unit 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 processing by the rewriting control unit 17 is performed in step S9, it is determined whether or not the shift amount correction is finished (step S10). If the shift amount correction is not finished, that is, for other elements. When performing shift amount correction, the process returns to step S5 and steps S5 to S
The process of 10 is repeated. When it is determined in step S10 that the shift amount correction is to be ended, the system ends the shift amount correction process and shifts to the next process.

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", the progressive dimension element group on the drawing to be subjected to the decimal point position correction is selectively designated (step S1.
2) Dimension data to be used as a reference for rearranging the dimension values of the progressive dimension in the designated progressive dimension element group is selectively designated (step S13).

The rewrite control section 17 determines the above-mentioned step S12.
And based on the information designated in S13, the dimension values of the progressive dimension element group designated by the element designating section 13 are rearranged with the decimal point position of the reference data designated by the reference data designating section 14 as a reference. The dimensional value position is corrected (step S14), and the progressive dimensions of the drawing data displayed on the display 3 and stored in the memory 16 are rewritten as necessary (step S15).

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

Here, an example of a specific operation in this system will be described in detail. First, C as shown in FIG.
In the menu on the editing screen of the AD system, "Annotation"-
If you select "Execute" (annotation means to enter annotations other than drawing such as dimension lines), the menu as shown in Fig. 4 will be displayed. In this menu, select "Dimension"-"Element" 5) is displayed, a menu as shown in Fig. 5 is displayed, and the prompt line at the bottom of the display 3, for example, "Please specify the type of dimension line" is displayed. This requires the operator to instruct the type of dimension line to be filled.

When "progress"-"execute" (meaning execution of progressive dimensions) is selected in this menu, the progressive dimension creation mode is entered, the menu as shown in FIG. 6 is displayed, and the prompt on the screen of the display 3 is displayed. The indication "Please indicate the type of the progressive dimension line" is displayed on the line, and the operator is required to indicate the type of the progressive dimension to be entered. When "Dimension correction" is selected in this menu, the progressive dimension correction processing mode is entered regardless of the type of the progressive dimension line selected at that time, and the menu shown in FIG. The message "Please specify the correction type" is displayed on the above prompt line, and the operator is requested to instruct which of the "decimal point position correction mode" and "shift amount correction mode" to select. It

The selection of these menus and the change thereof are performed by the operator operating the cursor movement key of the input device 2 or the mouse while moving the cursor bar on the menu while looking at the edit screen of the display 3. When "shift amount correction"-"execution" is selected in the menu of FIG. 7 and "shift amount correction mode" is selected, the system becomes "shift amount correction mode", and a menu as shown in FIG. 8 is displayed. It

In the menu shown in FIG. 8, normally, at the time of display, "single"-"designation" has been preferentially selected as shown in the figure. In this state, as shown in FIG. 8, the prompt line "Please specify the target element" is displayed, and the operator is requested to individually specify the progressive dimension element to be the target of the shift amount correction. To be done. When the first target element is designated by operating the mouse or the like, the instruction 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 "Execution" selected, and the prompt line on the screen displays "Please specify the reference element". As a result, the operator is required to instruct the progressive dimension element that serves as a reference for the shift amount correction.

When the standard progressive dimension element is designated by operating the mouse or the like, next, as shown in FIG. 11, "Enter shift amount" is displayed on the prompt line on the screen. This requires the operator to input the shift amount. When the shift amount is input as, for example, “30” (mm) by operating the keyboard or the like, as shown in FIG. 12, the designated object progressive dimension element on the drawing is based on the designated reference element ( That is, the reference element is not shifted), and the progressive dimension is rewritten by re-shifting with the input shift amount. In this state, the menu and prompt line prompt the instruction of the target element as shown in the figure, and when correcting the shift amount of other progressive dimension elements, the operation after the instruction of the target element similar to the above is again performed. repeat. In addition, when the correction of the shift amount is finished, "stop" is selected.

When the shift amount correction is completed, the screen returns to the correction mode selection screen similar to that shown in 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 the normal case,
When it is displayed, "single"-"designation" is preferentially selected, and the prompt line displays "please specify the target element", so that the decimal point position is displayed to the operator. Although it is required to specify the progressive dimension element to be corrected, for example, "inside the fence"-"designation" is selected, the target element is surrounded by an instruction frame, and "inside the fence"-"designation" is selected. Thereafter, as shown in the figure, the selection of the selected element is completed by selecting "in fence"-"end".

When the selection of the target element is completed, the menu as shown in FIG. 15 is displayed with "Execution" selected, and the prompt line on the screen displays "Please specify the standard dimensions". As a result, the operator is required to instruct the progressive dimension element that serves as a reference for decimal point position correction.

When a standard progressive dimension element is designated by operating a mouse or the like, as shown in FIG. 16, the dimension value of the designated progressive dimension element on the drawing is changed to that of the designated standard element. Based on the decimal point position (that is, the decimal point positions are aligned), they are rearranged and the progressive dimension is rewritten. In this state, the menu and the prompt line prompt the instruction of the further target element as shown in the figure. Furthermore, when the decimal point position correction of other progressive dimension elements is performed, again after the instruction of the target element similar to the above. Repeat the operation of. To end the correction of the decimal point position, select "Cancel". When the shift amount correction is completed, the screen returns to the correction mode selection screen having the same menu and prompt line display as in FIG. 13 or 7.

As described above, by designating the progressive dimension element to be modified, the reference data for shift modification, and the shift amount if necessary, of the already entered progressive dimensions, the drawings displayed and stored. Based on the instruction, the progressive dimension on the data can be rewritten into the progressive dimension re-shifted by the predetermined shift amount with reference to the reference data, based on the instruction. Further, correction of the shift amount and decimal point position correction of the dimension value of the progressive dimension can be performed very easily by almost the same operation.

In the above description, the shift amount is newly input during the shift amount correction, but the shift amount during the shift amount correction may be fixedly set in advance. Further, 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 simultaneously performed at once.

[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 the progressive dimension shift in the designated progressive dimension group is performed. By designating the dimensional data to be used as the reference, the data of the designated progressive dimension group is rewritten into the progressive dimension group which is subjected to a required shift around the designated dimensional data. It is possible to provide a progressive dimension correction method and device capable of easily and appropriately correcting the shift state of the progressive dimension with respect to the created progressive dimension and remarkably reducing the operation burden on the operator. it can.
