Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a schematic configuration of a CAD system incorporating a progressive dimension creating apparatus according to an embodiment of the present invention. In the CAD system of this embodiment, when an additional progressive dimension is entered in addition to the progressive dimension written on the drawing data, the progressive dimension element to be referred to at the time of the additional entry is designated, and further additional measurement points, Or, by designating additional measurement points and dimensional value positions, the type of progressive dimension and the origin for measuring the dimensions, etc. are common to the reference element, and the drawing data that is displayed and stored shows the additional measurement points. Data of progressive dimensions can be written.

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 and CAD processing including a progressive dimension creation processing for reference addition is executed. The input device 2 includes an operation input device such as a keyboard and a pointing device such as a mouse, and inputs operation input information by an operator and other external information necessary for CAD processing to the CAD processing unit 1. Display 3
Necessary information such as processed image information by the CAD processing unit 1 and information related to input by the input device 2 is displayed. 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, operates in association with the CAD processing unit 1, and stores data such as image information before, after, 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 process, the display control unit 11, the command input unit 12, and the reference element designating unit 13 for executing the progressive dimension creating process for adding the reference of the progressive dimension according to the embodiment of the present invention. , A measurement point / dimension value position designating section 14, an overlap determining section 15, a shift amount calculating section 16, a memory 17, and a writing control section 18.

The display control unit 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 including a progressive dimension reference additional entry command through an interactive operation with the screen of the display 3, for example. The command input unit 12 also performs processing for selectively designating whether the automatic shift mode is “on” or “off” when adding a reference. Therefore, the command input unit 12 controls the display control unit 11 as necessary.

The reference element instructing unit 13 functions at least when the command for adding the reference addition writing of the progressive dimension is input by the command input unit 12, and, for example, the display 3
Through an interactive operation with the screen, the operator performs a process for instructing the operator to indicate the progressive dimension element to be referred to when adding the progressive dimension, that is, the progressive dimension element to which the progressive dimension is added. Therefore, the reference element instruction unit 13 also controls the display control unit 11 as necessary.

The measurement point / dimension value position designating section 14 functions when at least the reference additional entry command of the progressive dimension is inputted by the command input section 12, and, for example, by an interactive operation with the screen of the display 3, A process for causing the operator to instruct the measurement point or the position of the measurement point and the dimension value when an additional progressive dimension is entered on the drawing is performed. Therefore, the measurement point / dimension value position designating section 14 also controls the display control section 11 as necessary. The measurement point / dimension value position designating section 14 may share the measurement point / dimension value position designating section used when creating a new progressive dimension in the CAD processing section 1.

The overlap determining section 15 functions when the automatic shift mode is set, and the reference element designating section 13 is provided.
Based on the measurement origin of the reference progressive dimension and the measurement point to be added according to the instruction from the measurement point / dimension value position designating section 14, the progressive dimension to be added is virtually provisionally arranged on the drawing and added. It is determined whether or not the dimensional values of the progressive dimensions overlap with each other and interfere with each other.

The shift amount calculating section 16 arranges an additional progressive dimension on the drawing based on the instruction of the reference element designating section 13 and the measurement point / dimension value position designating section 14 in the overlap determining section 15. The processing is performed when it is determined that the dimensional values of the progressive dimensions interfere with each other due to overlapping or the like, and a process of calculating a shift amount of the dimensional values necessary to prevent the dimensional values of the progressive dimensions from interfering with each other is performed. Shifting the dimension value means bending the dimension line to shift the dimension value position.

The overlap determining unit 15 and the shift amount calculating unit 16 may also share the overlap determining unit and the shift amount calculating unit used for the automatic shift when creating a new progressive dimension in the CAD processing unit 1. The memory 17 stores information including CAD drawing data to be displayed by the display control unit 11. The storage contents of the memory 17 are transferred to the storage device 5 as needed. This memory 17 is a CA
The memory used in the normal CAD processing in the D processing unit 1 may be shared.

The writing control section 18 is provided on the drawing data displayed on the display 3 and stored in the memory 17, at the dimension value position and the measurement point obtained by the measurement point / dimension value position designating section 14, or Based on the measurement point and the shift amount obtained by the measurement point / dimension value position instructing unit 14 and the shift amount calculating unit 16, the progressive dimension element is designated based on the origin of the progressive dimension element designated by the reference element instructing unit 13. Write progressive dimension data of the same type.

Next, the operation relating to the reference addition of the progressive dimension in the CAD system having such a configuration will be described with reference to FIG.
This will be described in detail with reference to the flowchart shown in FIG. 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, when a progressive dimension reference addition command is selected by the operator via the command input section 12 of the CAD processing section 1 (step S1), the system is set to the progressive dimension reference addition mode (step S2).

When the progressive dimension reference addition mode is entered, the operator is instructed via the command input section 12 whether the shift mode, that is, whether the automatic shift mode is "on" or "off" (step S).
3), the reference element instructing unit 13 of the CAD processing unit 1 gives an instruction by the operator of an existing progressive dimension element to be referenced when adding a progressive dimension on the drawing (step S4). The instruction of the reference target by the reference element instruction unit 13 is performed by an operator's input request via the screen of the display 3, and the operator accordingly performing an instruction operation using a cursor on the screen.

Next, the measurement point / dimension value position instructing section 14 instructs the operator of an additional measurement point on which a progressive dimension should be entered on the drawing (step S5), and the automatic shift mode is turned "ON" / “Off” is determined (step S6). When it is determined in step S6 that the automatic shift mode is "ON", the overlapping determination unit 15 virtually provisionally arranges the progressive dimension to be added based on the information already given (step S7). Furthermore, it is determined whether or not the dimension values overlap with each other due to the addition of the progressive dimension and thus interfere with each other (step S8).

When it is determined in step S8 that the progressive dimension values interfere with each other, the shift amount calculating section 16
Then, the shift amount of the dimension value corresponding to the additional measurement point necessary to prevent the dimension values of the progressive dimension from interfering with each other is calculated (step S9), and the write control unit 18 measures the measurement point / dimension value position. Based on the additional measurement points and shift amounts obtained by the instruction unit 14 and the shift amount calculation unit 16,
The additional progressive dimension data of the same type based on the common origin as the reference object designated by the reference element designating unit 13 is written on the drawing data displayed on the display 3 and stored in the memory 17. (Step S
10).

In step 10, when the additional progressive dimension data is written, it is determined whether or not the end of the reference addition of the progressive dimension is instructed (step S11). If it is finished, the process proceeds to the next process, and it is not finished. In this case, the process returns to step S5, and the processes after step S5 are repeated.

When it is determined in step S6 that the automatic shift mode is "OFF", the measurement point / dimension value position designating section 14 designates the position where the dimension value to be added should be arranged (step S12). In the write control unit 18, the reference element designating unit 13 is based on the additional measurement point and dimension value position obtained by the measurement point / dimension value position designating unit 14.
The additional dimensional data of the same type based on the common origin as the reference object indicated by
Is written on the drawing data displayed on the screen and stored in the memory 17 (step S10).

Also in the case of this automatic shift mode "OFF",
In step 10, when the additional progressive dimension data is written, it is determined whether or not an instruction to finish adding the progressive dimension has been instructed (step S11). If it is finished, the process proceeds to the next process, and if it is not finished, the step is finished. The process returns to S5, and the processes after step S5 are repeated.

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), a menu as shown in Fig. 4 will be displayed. In this menu, select "Dimension"-"Element" 5) is displayed, a menu such as that shown in Fig. 5 is displayed, and "Please specify the type of dimension line" is displayed on the prompt line at the bottom of the display 3, for example. This requires the operator to instruct the type of dimension line to be filled.

When "progressive"-"execute" (meaning execution of progressive dimensions) is selected in the menu of FIG. 5, the process shown in FIG.
A menu like the one shown below is displayed, and the prompt line on the screen of the display 3 displays "Please indicate the type of progressive dimension line", so that the operator is requested to indicate the type of progressive dimension to be entered. To be done. When "Add reference" is selected in this menu, the mode is changed to the progressive dimension reference addition mode regardless of the type of the progressive dimension line selected at that time, and the menu as shown in FIG. The indication "Please indicate the element to be referred to" is displayed on the above prompt line, and the operator is requested to indicate the progressive dimension element to be referred to.

In the menu shown in FIG. 7, "auto shift" is set to "on" (the "□" before "auto shift" is "■").
Then, when the user designates the reference target element and selects “execute”, a menu as shown in FIG. 8 is displayed. In this menu, in the normal case, "automatic recognition"-"execution" has already been preferentially selected at the time of display. The selection of the menu and the change thereof are performed by the operator operating the cursor movement key or the mouse of the input device 2 while moving the cursor bar on the menu while looking at the edit screen of the display 3.

In this state, as shown in FIG. 8, the prompt line "Please indicate the point to be measured" is displayed, and the operator is requested to indicate the measurement point of the progressive dimension to be added. To be done. When a measurement point is designated by operating a mouse or the like, as shown in FIG. 9, based on the data designated so far, an additional progressive dimension of the same type with respect to the progressive dimension of the reference object and the common origin is used as a reference. Is written and a message "please specify the point to be measured" is displayed on the prompt line, thereby requesting the operator to instruct the next measurement point on the drawing.

When the progressive dimensions are written, if the dimension values interfere with each other, the dimension values are automatically shifted and written as shown in FIG. In this way, by repeating the indication of the measurement points, the progressive dimensions for many additional measurement points are sequentially written. When writing the dimension values, the dimension values are sequentially and automatically shifted so that the dimension values do not interfere with each other.

In the menu of FIG. 10 similar to that of FIG. 7, after the “auto shift” is turned “off” as shown in the figure (“■” before “auto shift” becomes “□”), the reference target element , And select “execute”, a menu as shown in FIG. 11 is displayed. Also in this menu, in the normal case, "automatic recognition"-"execution" is already preferentially selected at the time of display.

In this state, as shown in FIG. 11, a message "please specify the point to be measured" is displayed on the prompt line to request the operator to instruct the measurement point of the progressive dimension to be added. To be done. When the measurement point is designated by operating the mouse or the like, next, as shown in FIG. 12, a cursor CS indicating the position is displayed on the dimension line and the dimension value, and the prompt line on the screen displays "the position for displaying the dimension value. Please indicate. ”
The operator is required to indicate the position on the drawing where the dimension value should be placed.

When the dimension value position is designated by operating the mouse or the like, as shown in FIG. 13, based on the data designated up to that point, the progressive dimension of the reference object and the common origin of the same type are used as a reference. An additional progressive dimension is written and the prompt line "Please indicate the point to be measured" is displayed to request the operator to indicate the next measuring point on the drawing.

In this manner, by progressively repeating the designation of the measurement points and the dimension value positions, the progressive dimensions for a large number of additional measurement points are sequentially written. In the above,
Although the progressive dimensions to be added are sequentially input one by one, it is also possible to collectively enter the information about a plurality of additional measurement points and then collectively write the progressive dimensions for these measurement points. .. Also, automatic shift "on"
The system may be configured to perform only one of the mode 1 and the automatic shift “off” mode.
