Description

[0001]
[Industrial application fields]
The present invention relates to a menu display method used for parameter setting after selection of a graphic element in a CAD system.
[0002]
[Prior art]
In a CAD system, parameters such as line type, character size, and scale may be set when various operations and processes are instructed to the system. This type of parameter is usually not displayed at all on the display screen or is often displayed in a very narrow fixed area of the display screen. However, when there are a large number of parameters to be set, it is difficult to display all the parameters, so when a target element related to parameter setting is selected, a parameter setting menu is selectively displayed. Systems that do this are also known.
Conventionally, this type of menu is generally displayed at a fixed position on the display screen. In addition, a system is also known in which a parameter setting menu is displayed in the vicinity of the cursor position in order to minimize the amount of movement of the cursor used for parameter setting.
[0003]
[Problems to be solved by the invention]
However, in the conventional menu display method described above, the parameter setting menu is displayed at a fixed position on the display screen or in the vicinity of the cursor position, so that the selected element may be hidden under the menu. Especially in the latter case, the menu appears at the position where the element is selected, and the selected element is necessarily hidden under the menu. For this reason, there is a problem that it is difficult to set parameters while confirming the selected element on the screen.
[0004]
The present invention has been made to solve the above problems, provides a CAD system capable of making sure the selected element on the screen, you set the parameters of the selected element by the menu for setting parameters The purpose is to do.
[0005]
[Means for Solving the Problems]
The present invention provides an input means for inputting position information, a cursor position identifying means for identifying the position of the cursor based on the position information from the input means, a graphic element to be edited, and the cursor position identifying means. A display means for displaying a cursor at the identified position, an element selection means for selecting a graphic element existing in the vicinity of the cursor position identified by the cursor position identification means as a selection element, and an element selection means Window display element cutting means for identifying the existing area of the selected element from the selected element information and cutting out the display data of the existing area of the selected element from the display data displayed on the display means; Display data cut out by the output means and a menu for setting the parameter of the selected element are simultaneously displayed on the display means. Characterized by comprising a display control means for changing a display form of the display data of the selected elements the displayed simultaneously in accordance with the change input parameters by the menu causes.
[0006]
[Action]
According to the present invention, since a window is provided in a menu and the target element is displayed in the window, a parameter setting operation can be performed using the menu while checking the target element on the screen.
[0007]
【Example】
Embodiments of the present invention will be described below with reference to the accompanying drawings.
FIG. 1 is a functional block diagram of a CAD system according to an embodiment of the present invention.
The input device 1 includes a pointing device such as a mouse and code input means such as a keyboard. Position information from the mouse or the like of the input device 1 is input to the cursor position identification unit 2, and the position of the cursor operated by the mouse or the like is identified. The position identification result of the cursor position identification unit 2 is given to the display control unit 3 so that the cursor is displayed at the identified position on the display 4. The position identification result from the cursor position identification unit 2 is also supplied to the element selection unit 5 and the command execution unit 6. The element selection unit 5 selects a graphic element existing in the vicinity of the cursor position identified by the cursor position identification unit 2 from the CAD processing unit 7, and sets the graphic element as a selection element. The command execution unit 6 executes the command displayed at the cursor position identified by the cursor position identification unit 2 and performs a designated process on the CAD processing unit 7.
[0008]
Further, the window display element cutting unit 8 identifies the existence area of the selected element from the information of the selected element given from the element selecting unit 5, and among the display data supplied to the display control unit 3, Cut out the display data of the existing area. The cut display data is given to the dialog menu display control unit 9. The dialog menu display control unit 9 includes display information of a dialog menu including a window therein. Then, the dialog menu display control unit 9 appropriately enlarges / reduces the cut-out display data to the size of the window prepared in the dialog menu, and then pastes it on the window part, together with other display information, the display control unit Give to 3. Thus, a dialog menu having a window at a predetermined position on the display 4 is displayed.
The output device 10 is a plotting device such as a plotter that outputs a drawing according to the control of the CAD processing unit 7.
[0009]
FIG. 2 is a diagram showing an example of a screen displayed on the display 4 of this CAD system.
The screen 11 includes a graphic display area 12, a main menu 13, and a message display line 14. This example shows a display example at the time of adding a dimension line, and a portion surrounded by a dotted line in the figure is a target element 15 to be edited. The target element 15 includes a selection element 16 selected for automatic recognition of the end point distance, a cursor 17 for designating the position of the dimension line, an auxiliary line 18 indicating the position of the dimension line, and the like. In other words, the target element 15 includes all of the portions that are directly changed during the editing operation or that are the operation target.
[0010]
When the operator confirms the position of the dimension line by clicking the mouse or the like in accordance with the message “Specify the position of the dimension line” displayed on the message display line 14, as shown in FIG. A dialog menu 19 for setting parameters related to the element 15 is displayed. At this time, the display position of the dialog menu 19 may be a fixed position in advance, or may be displayed at the position of the cursor 17 in order to reduce the amount of movement of the cursor.
[0011]
As shown in FIG. 3, when the dialog menu 19 is displayed, the target element 15 may be hidden under the dialog menu 19. For this reason, in this system, a window 20 is provided in a part of the dialog menu 19 and the target element 15 is displayed in the window 20.
[0012]
FIG. 4 is a diagram illustrating an example of the dialog menu 19. In this dialog menu 19, in addition to the window 20 described above, as a parameter of the dimension line to be entered, the point selection for measuring the end point distance is automatically recognized, the pen number is white, The display color is light blue, the pitch is a standard pitch, the line type is a solid line, the dimensional format is “Value”, the character size is 3.2 mm, and the terminal symbol is It is set to be inner open arrow 1 or the like. In order to change these parameters, a necessary parameter in the dialog menu 19 is selected with the cursor 17 and the set value may be changed. When the parameter is changed, the display form of the target element 15 displayed in the window 20 is changed accordingly.
[0013]
【The invention's effect】
As described above, according to the present invention, the window is provided in the menu and the target element is displayed in the window. Therefore, the parameter setting operation is performed using the menu while checking the target element on the screen. There is an effect that it can be performed.
