Abstract

PURPOSE:To enable graphic deformation only by inputting a small number of parameters by setting parameter values by using a standard table for defined parameters. CONSTITUTION:A graphic deformation data input means 11 is operated to read graphic data in and parameters for the graphic deformation are defined by the definition part 121 of a figure deformation defining means 12 with commands. A standard table part 122 reads the parameters defined by the definition part 121 in the standard table and registers the parameters values for the parameters in the standard table. Then an output part 123 registers graphic deformation definition information, which is generated by the means 11, definition part 121, and table part 122 in a data base. Then a graphic deforming means 13 reads the figure deformation definition information in and performs the graphic deformation. Consequently, a value is only inputted for a parameter as a retrieval key of the standard table to performs the graphic deformation.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a CAD system, and more particularly to an automatic figure deformation method that enables flexible editing and design in design work. [Conventional technology] Design technology requires a CAD system to have a shape transformation function for editing drawings. Conventionally, a figure transformation data input means for reading figure data, a figure transformation definition means for defining and saving parameters for figure transformation by a command, a figure transformation execution means for inputting values to the definition parameters and transforming the figure, In an automatic figure transformation method that includes a figure transformation output means that saves updated figure transformation definition information after transformation, when parameter values are input during figure transformation, parameter values are input for all defined parameters. I was confused about which parameter corresponds to which definition in shape transformation.

[Problem to be solved by the invention]

The conventional automatic figure transformation method described above has the disadvantage that parameter values must be entered for all parameters defined during figure transformation, since the individual defined parameters are not related. In addition, inputting all parameter values also has the disadvantage that it is necessary to remember which parameter corresponds to which part of the figure.

[Means to solve the problem]

The automatic figure deformation method of the present invention comprises a figure deformation data input means for reading figure data necessary for figure deformation, a figure deformation definition means for defining and saving parameters for figure deformation using commands, and said figure deformation definition means. The present invention is characterized by comprising a figure transformation executing means for inputting values to parameters defined by the figure to transform the figure, and a figure transformation output means for saving the updated figure transformation definition information after the figure transformation. [Example] Next, the present invention will be described with reference to the drawings.

As shown in FIG. 1, the automatic figure deformation method of the present invention includes a figure deformation data input means 1 for reading figure data, and a definition part 121 for defining parameters for figure deformation using commands. A graphic deformation definition means 12 consisting of a standard table part 122 that defines arbitrary values for defined parameters, an output part 123 that stores graphic deformation definition information, and an input part that calls the graphic deformation definition information in order to execute the graphic deformation. 131, a graphic transformation execution means 13 consisting of an execution unit 132 for inputting values to defined parameters, and a graphic transformation output means 14 for storing updated graphic transformation definition information after graphic transformation.

The figure deformation data input means 11 takes in figure data, coordinate values of each element, and the like.

The definition section 121 of the graphic deformation definition means 12 defines parameters for the graphic data read by the graphic deformation data input means 11. Graphical transformation commands include parallel movement, enlargement/reduction, rotational movement, and several other commands, and by combining these commands, all kinds of graphical transformations are possible.

The standard table section 122 takes in the parameters defined by the definition section 121 into a standard table. Therefore, register values for the parameters in the standards table. By using the standard table section, the execution section 132 simply inputs one parameter value to search for other parameter values and uniquely determine them. However, if the same parameter value is registered at the time of parameter value registration, it will not be determined uniquely, so one parameter must be set as a search key in the standard table section 122, and a different value must be registered for that parameter value. No. The data created by the figure deformation data input means 11, the definition section 121, and the standard table section 122 becomes the figure deformation definition information. The output unit 123 registers the graphic deformation definition information in the database, and terminates the graphic deformation definition means 12. The input unit 131 of the figure transformation execution means 13 includes the figure transformation data input means 1l.
The graphic deformation definition information defined from to the graphic deformation definition means 12 is read from the database.

The execution unit 132 deforms the figure by inputting values to the parameters defined by the definition unit 121. However, if parameter values are registered in the standard table, shape transformation can be performed simply by inputting the values into the parameters that serve as search keys. The figure transformation output means 4 uses the updated data after the figure transformation as figure transformation definition information and registers it in the database.

The operation when transforming the figure in Figure 2 will be explained with reference to Figure 1. The figure data of FIG. 2 is read in by the figure deformation data input means 11. At this time, the figure data includes coordinate values (0, O), (100.0), (100,100
), (0.100) are read. Define the command in the definition section 121 as follows. Set the parameters to A and B using the parallel movement command, and set P1 as the reference, P
2. Move P3 to follow the movement of P2. Next, use the same parallel movement command to change the parameters to C and D.
P1 is the standard and P4 is the target. Move P3 to follow the movement of P4. Parameter values are defined for parameters in the standard table section 122 as shown in FIG. Set the parameter that will be the search key at this time to A. The output unit 123 registers the graphic deformation definition information in the database.

The input unit 131 reads the graphic deformation definition information. Execution part 1
In step 32, enter values for the definition parameters. The search key parameter is A and enter the value in the definition parameter. Since the search key parameter is A and the standard table is defined as shown in Figure 3, by inputting A=50, B=0,
Determine C=O and D=50, and transform the figure as shown in Figure 4. The graphic deformation definition information updated by the graphic deformation output means 14 is registered in the database.

〔Effect of the invention〕

As explained above, in the present invention, when editing figures in design work, by setting parameter values using a standard table for definition parameters, it is possible to transform figures simply by inputting the minimum parameters. Also, there is no need to remember which shape transformation a parameter corresponds to. (Margin below)
