DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drawing creation method using a parametric basic figure, and more particularly to a drawing creation method for efficiently processing a basic figure when a plurality of subject parameters are input. Things.

[0002]

2. Description of the Related Art Conventionally, as shown in Japanese Patent Application Laid-Open No. 1-236363, a drawing creation method using a parametric basic figure first requires an operator to register a plurality of registered basic figures from a menu on a screen or a tablet. The name is designated by selecting or inputting the name given at the time of registration of the basic figure, and the basic figure is displayed on the screen. Next, when a set of parameters defined at the time of registration of the basic figure is input, the basic figure is deformed according to the value of the input parameter, and the figure is designed. After that, the figure is registered by further inputting the registration name given to the figure.

[0003]

However, the conventional drawing method has the following problems. Since parameter input can be performed only once for one parametric basic figure call, if you want to create multiple figures by inputting multiple subject parameters for the same basic figure, call the basic figure The input and registration of the figure to be created had to be repeated, which was very inefficient. If there is a parameter that takes a common value in the input of a plurality of subjects, the same parameter value must be key-inputted each time it is input, so that the burden on the operator is large and the risk of input errors has increased. In general, there are many cases where actual deformation of a figure is not necessarily required except for the case where CAM data is created. In this case, it suffices to have a basic figure and a parameter table. However, the method using parametric basic figures creates figures for the number of parameters entered,
The number of drawings increases unnecessarily, and man-hours and cost burdens for printing and managing drawings are increased. Therefore, conventionally, in such a case, a drawing composed of the basic graphic and the parameter table has been drawn by a separate drawing means. However, since this method cannot cope with a case where a deformed figure is required due to a change in the situation, the figure must be created again by a method using the basic figure, which has been troublesome twice. Also, the risk of parameter input errors has increased.

An object of the present invention is to solve the above-mentioned problem. By inputting parameters of a plurality of subjects continuously and minimizing the number of times of inputting parameters, a parametric basic figure with few input errors can be efficiently created. The purpose is to provide a drawing creation method using the drawing. In addition, a drawing consisting of a basic figure and an input parameter table is left, and the basic figure can be fixed from the drawing at an arbitrary timing, so that the efficiency of drawing creation and the burden of drawing printing and drawing management are increased. It is an object of the present invention to provide a drawing creation method using a parametric basic figure in which the number is reduced.

[0005]

In order to solve the above-mentioned problems, in a graphic creating method according to the present invention, a basic graphic is registered in advance using CAD, and a parameter is registered for each subject from the registered basic graphic. In a drawing creation method for designing a figure by giving a parameter, means for creating a parameter table as a figure that allows parameter input of a plurality of subjects,
Means for inputting a parameter to the parameter table, means for displaying the input parameter value in a corresponding column of the parameter table when the parameter is input, and means for storing the input parameter value as attribute data of the table The parameter table is registered together with the basic figure at the time of registration of the parametric basic figure, and at the time of graphic design, a plurality of subject parameters are input continuously while displaying the input parameters in the corresponding columns of the parameter table. After inputting one or more parameters, the basic figure is fixed by the number of input subjects by instructing execution, and the fixed figure is individually registered with the registration name specified at the time of parameter input. I have. In addition,
The fixation of the basic graphic means that the dimensions of each part are determined by giving parameter values to the basic graphic, and the graphic is deformed according to the dimensions.

Further, the figure creating method according to the present invention
In the drawing creation method in which a basic figure is registered in advance using D and a parameter is assigned to each subject from the registered basic figure, a common value is used for inputting a plurality of subjects among input parameters. Is separated from the parameter table as a common parameter. Further, in the drawing creation method according to the present invention, a basic drawing is registered in advance using CAD, and parameters are input for each subject from the registered base drawing. It is characterized in that registration and fixation of a basic figure for which parameters have been input can be freely selected.

[0007]

[Function] A parameter table which allows input of parameters for a plurality of subjects is registered together with a parametric basic figure. In addition, by registering a common parameter table as needed, parameter input of a plurality of subjects can be efficiently performed. Furthermore, after inputting parameters, it is possible to select whether or not to fix the basic figure. If not, register the basic figure, parameter table and common parameter table as a single drawing and use it as a drawing. It should be noted that the drawing is called only when the necessity arises, and the execution of the drawing is instructed to fix the basic figure.

[0008]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an example of a registered figure according to a basic drawing creation method of the present invention. In the figure, 1 is a parametric basic figure, and 2 is a parametric dimension line. 3
Is a parametric table, and a parametric basic figure 1
From the parameters (A, B, H, V,
T), and the name is entered in the registered name column.

[0009] By registering a parameter table 3 which enables input of parameters for a plurality of subjects together with the parametric basic figure 1, the basic figure can be called only once when inputting parameters for a plurality of subjects for the same basic figure. Will be done. Further, by providing a name field at the time of registration in the parameter table 3 and inputting the registered name together with the parameter input, the fixed figure can be automatically registered. By these actions, the process of creating and registering a plurality of figures by inputting parameters of a plurality of subjects for the same basic figure is greatly improved.

FIG. 2 is a flowchart showing the procedure for registering the basic figure in FIG. In the figure, the numerical value following the symbol S indicates the step number. Step S3 is omitted in order to match with another flowchart described later. [S1] The parametric basic figure 1 is drawn using the CAD function. [S2] The parametric dimension line 2 is plotted by the conventional parametric dimension plotting means, and parameter names (for example, A, B, H, V, T, etc.) are added. [S4] The parameter table creation means automatically inputs the number of rows in the table and designates a drawing position to automatically draw the parameter table 3. [S5] A name to be given to the created parametric basic figure is input and stored in the storage device under that name.

FIG. 3 is an example of another registered figure and a fixed figure according to the drawing creating method of the present invention. In FIG. 1A, reference numeral 4 denotes a common parameter table, which gives common parameters (A, B, T in the example) common to each part from the parametric basic figure 1. It is the same as FIG. 1 except that this common parameter table 4 is added, and the description of the other is omitted. When inputting a plurality of subject parameters for the same basic figure as described above, parameters that take the same value all in a group of design objects or the like appear. For example, in the case of a building exterior wall panel, the value of the thickness T varies depending on each building.
It is a common value in the same property. Such parameters are positioned as common parameters, and are collectively referred to as a common parameter table 4 and registered together with the parametric basic figure 1 and the parameter table 3. This eliminates the need to input the same value many times, which is efficient and prevents input errors. (B) is a figure deformed based on the parameter values input to the registered figure in (a).

FIG. 4 is a flow chart showing the registration procedure of the basic figure in FIG. Note that the flowchart is the same as the flowchart in FIG. 2 except that step S3 is added, and thus only step S4 related to step S3 will be described. [S3] The common parameter table creating means specifies common parameter names (A, B, T in the example) to be used as common parameters, and designates a drawing position to automatically draw the common parameter table 4. An error will occur if a parameter name that is not in the drawing is specified. [S4] The parameter table creation means automatically inputs the number of rows in the table and designates a drawing position to automatically draw the parameter table 3. In this case, a parameter name for which no common parameter is indicated is set in parameter table 3.

FIG. 5 is a flowchart showing the procedure of a method for creating a drawing using a parametric basic figure according to the present invention. [S21] A desired basic figure is called out by selecting a menu or inputting a registered name from a plurality of basic figures registered in advance by the basic figure registration procedure of FIG. 4 and displayed on the CAD drawing. [S22] Common parameters are input by the common parameter input means. The parameter value input by key is displayed in a predetermined column of the common parameter table. [S23] If the input of the parameters is completed, the process proceeds to S25, and if not, the process proceeds to S24. [S24] The individual parameters are input by the parameter input means, and the part name and the registered name are input as additional information in units of one item (one line). The parameter value or the like input by key is displayed in a predetermined column of the parameter table. [S25] If the figure is to be fixed, proceed to S26, otherwise proceed to S27. [S26] First, parameter values are read from the common parameter table and set in the memory. Next, the parameter values and the like are read out from the parameter table line by line, set in the memory, and the figure is deformed in accordance with the values of the common parameters set in the memory. Thereafter, the data is stored in the storage device under the name input as the registered name. This processing is performed in an area different from the memory area where the input basic graphic exists. This process is repeated for the number of input cases (the number of lines). [S27] To register a basic figure and a parameter table, enter S
Go to 28, otherwise end. [S28] A registered name to be given to the basic figure in which the parameter is set is input to the parameter table and the common parameter table, and the registered name is stored in the storage device.

As described above, the figure after inputting the parameters is not fixed, but the basic figure and the input parameter table are registered as one drawing. Normally, such drawings are often sufficient in areas other than the processing department such as the design, production control, and assembly departments. On the other hand, when the CAM process is performed in the processing section, individually deformed figures are required. However, when the NC processing apparatus is not used, the same drawing form as another section may be used. However, in many cases, whether or not CAM processing is performed in processing is not determined at the time of drawing creation. Therefore, usually, a drawing consisting of a basic figure and a parameter table is used, and only when necessary in the CAM processing, the drawing is called and a figure which is individually deformed by a procedure of fixing the drawing described later is created. . Further, since the figure created here is only used in the CAM processing, drawing printing is unnecessary, and the graphic data itself can be deleted after the CAM processing. This makes it possible for each department to work with drawings in the most appropriate form. Further, since the number of registered drawings is minimized, management becomes easy and the number of printed drawings is reduced, so that business can be efficiently and economically promoted.

FIG. 6 is a flowchart showing a procedure for fixing a drawing according to the present invention. [S31] A drawing for which parameters have been input is called from among a plurality of registered figures stored in advance in a storage device. [S32] A registration name to be fixed is specified. It is also possible to indicate all the registered names at once. [S33] If the figure is to be fixed, the process proceeds to S34, otherwise the process ends. [S32] The fixing of the parametric basic figure and the registration of the drawings are performed for the number of instructions.

[0016]

As described above, according to the graphic forming method of the present invention, the means for inputting a parameter to the parameter table including the common parameter table, and when the parameter is input, the input parameter value is displayed in the corresponding column of the parameter table. And a means for storing the input parameter values as attribute data of a table. The parameter table is registered together with the basic graphic at the time of registration of the parametric basic graphic, and the input parameter is stored in the parameter table at the time of graphic design. Input the parameters of multiple subjects continuously while displaying them in the corresponding column of, and after inputting at least one parameter, fix the basic figures by the number of input subjects by instructing execution, and fix the figure Is registered individually with the registration name specified at the time of parameter input. When inputting parameters for multiple subjects, only one call to the basic figure is required, and a fixed figure can be registered automatically. Parameters for multiple subjects can be input for the same basic figure at the same time. The process of creating and registering is made much more efficient. Also, the common parameter table eliminates the need to enter the same value many times,
It is efficient and can prevent input errors. By arbitrarily selecting the fixation of the figure after inputting the parameters, it is possible for each department to work on the drawing in the optimal form, the number of registered drawings is minimized, and the management becomes easy. The number of drawings printed can be reduced, and business can be efficiently and economically promoted.
