Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention is based on computer aided technology (CAD).
This invention relates to a cursor window display method in which a window area designated by a cursor is enlarged and displayed in an enlarged drawing display area set separately from the entire drawing display area in a computer-aided design system.

[Conventional technology]

A CAD system uses a graphic display to create figures by treating a specific area of the screen as a drawing paper.
Projecting and editing are performed while interacting with people. In this case, you can input commands using a so-called pointing device such as a mouse, tablet, or light pen, and a keyboard.
It inputs the coordinates of each point of a figure and other data, processes it with commands, and stores it in a storage device or displays it on the screen.

By the way, when performing input processing such as creating, projecting, and modifying a figure as described above, it is necessary to confirm that a plurality of pieces of drawing data are complicated when inputting the details of the figure. Conventionally, input of details in such cases has been confirmed by enlarging the details to fill the screen using an enlargement command.

[Problem that the invention seeks to solve]

Screen enlargement generally requires processing time, and frequent use of this processing results in an increase in input time. Therefore, proceeding without checking reduces the time required for input and often causes trouble. In addition, due to the performance of the display, multiple drawing elements may be displayed as one drawing element, so it is often possible to proceed without noticing the incorrect input, and if the details overlap completely, the desired drawing element will not be displayed. Sometimes it is impossible to get there. Furthermore, if details are enlarged to fill the entire screen using an enlargement command, the entire drawing cannot be seen, making it difficult to see the relationship between the entire drawing and the enlarged details, which may cause input errors.

The present invention is based on the above considerations, and an object of the present invention is to provide a cursor window display method that allows detailed confirmation and input while viewing the relationship with the overall drawing.

[Means for solving problems]

For this purpose, the cursor window display method of the present invention is
Setting an entire drawing display area that displays the entire drawing and an enlarged drawing display area that enlarges and displays drawing elements in the window area specified by the cursor in the entire drawing display area,
A cursor window display method for a computer-aided design system that draws a desired figure on a display screen according to inputting drawing commands and data, in which one drawing element among a plurality of drawing elements in the window area is designated as a designated element by an input instruction. This method is characterized in that the designated element is selected and displayed in a display am different from other drawing elements to search for the drawing element.

[Effect]

The cursor window and window display method of the present invention includes an entire drawing display area that displays the entire drawing and an enlarged drawing display area that enlarges and displays drawing elements in the window area specified by the cursor in the entire drawing display area. This setting makes it easy to understand the relationship between the entire drawing and the enlarged details, and when drawing elements are selected by input instructions,
One drawing element out of multiple drawing elements is selected as the specified element and displayed in a different display mode from other drawing elements, so the input drawing element can be easily confirmed even in the details of a crowded drawing. , can reduce input errors. Further, since it is possible to avoid repeating enlarged display of details and display of the entire drawing in the entire drawing display area, processing speed can be improved.

〔Example〕

Examples will be described below with reference to the drawings.

FIG. 1 is a functional block diagram for explaining one embodiment of the cursor window display method according to the present invention, and FIG. 2 is a diagram showing a display example using the cursor window display method according to the present invention. In the figure, 1 is an input section, 2 is an input data analysis processing section, 3 is a database, 4 is a drawing data holding section, 5
6 is a cursor information holding section, 6 is an entire drawing display control section, 7 is an enlarged drawing display control section, 8 is an entire drawing display area, 9 is an enlarged drawing display area, and A is a line segment.

In FIG. 1, an input unit 1 is used to input various commands and data, and is comprised of a so-called pointing device such as a mouse, tablet, and light pen, and a keyboard. The database 3 stores various drawing data (drawing elements) such as line segments and circular arcs, and the drawing display information holding section 4 holds information on clipping areas to be clipped and displayed and information on jumps. The cursor information holding unit 5 holds information on the window area of the cursor displayed in the entire drawing display area 8. Note that the display attributes of the drawing data are also specified in the drawing display information holding unit 4.

The input data analysis processing section 2 analyzes various commands and data input through the input section 1 and performs predetermined processing, and determines which area in the database 3 to display and the display attributes of which elements. The information for displaying in the entire drawing display area 8, such as whether to change it to something different, is stored in the drawing display information holding unit 4, or the information on the window area of the cursor held in the cursor information holding unit 5 is changed. or The overall drawing display control unit 6 controls display in the overall drawing display area 8 based on the information in the drawing display information holding unit 4, and the enlarged drawing display control unit 7 controls information held in the cursor information holding unit 5. The drawing data of the portion specified by the information of the window area of the cursor is displayed in the enlarged drawing display area 9.

The cursor has a search range (cursor window,
However, in the above configuration, when a point force or element pick is performed with this cursor, or when an input intended only for partial enlargement is performed, the size on the screen is set. Elements included within the search range are displayed in an enlarged manner in an enlarged drawing display area 9 at a specific location, and input points or picked elements are made to have different display attributes, such as patterns or colors, so that they can be discriminated. Such a display confirms whether the input point or pink element is the one desired or the details of interest. In addition, if the input point or pick element is not what you want in the enlarged display, you can change the input point or pick element to the next input point or element in the window by performing an input (command specification, key input, etc.) that instructs to change the input point or pick element. The final candidate becomes a determined input point or pick element by the input at the end of 0 transfer or the input at the next input step that changes the candidate to a display attribute different from the others. If the input point or pick element is not the desired one, the input may be obtained by inputting or picking the desired point or element within the enlarged drawing display area 9.The specific display example shown in FIG. 2 is the entire drawing display. Area 8
The center P+ of the circular figure 31, S, of the overall drawing displayed in
When drawing a line segment A between , Pg, the center PI of the circular figure s1
After placing a dot on the center P3 of the circle figure S2, the cursor is displayed in the enlarged drawing display area 9 (cursor window) to show how the center P2 of the circle figure S2 is made dot. It is something that exists. At this time, the circular figure S
The center P2 of t is displayed as an input point display with a display attribute different from other display attributes. Here, as the display attributes, display attributes that can be distinguished from each other may be used, such as displays with different hues, brightnesses, and saturations, blinking displays, inverted displays, dot pattern auxiliary displays, etc.

FIG. 3 is a diagram for explaining an example of a process when a pick element is displayed in an enlarged manner, and FIG. 4 is a diagram for explaining an example of a process when a point power is displayed in an enlarged manner. An example of processing when enlarging and displaying a pick element will be described below.

■ Recognize that there was an element pick. Next, perform the process (■).

■ Search for each element within the cursor search range of the entire drawing display area (within the range that should be displayed in the cursor window). Next, perform the process (■).

■ Perform a clipping operation on the search element within the search range. Next, perform the process (■).

■ Display elements in the cursor window. Next, perform the process (■).

■ Performs zero-order ■ to ■ processing to calculate the distance between the cursor center and the search element.

■ Confirm search elements.

■ Display the search element closest to the cursor center in a different color in the cursor window.

■ Display the search element closest to the cursor center in a different color on the display screen of the entire drawing. Further, as described above, the display attribute is not limited to color, and may be a display attribute that allows the element to be distinguished from other elements.

Note that the above process (■) is not necessarily limited to the method of determining based on the distance between the cursor center and the search element, but may also be determined based on various criteria such as input order, reverse input order, priority element type, etc. .

In the case of enlarging and displaying the input point, there is no particular difference from the process shown in FIG. 3 in which the pick element is enlarged and displayed as shown in FIG. 4, so a description thereof will be omitted. In Fig. 4, the cursor interior points are the end points of elements, intersection points, and upper points of elements (legs of perpendicular lines).
etc. However, since the top point of an element is generally the closest distance, distance determination may be performed for end points and intersection points, and the top point of the element may be placed at the back of the priority order. You can also judge the distance between the cursor center and each point by selecting the elements in the input order or reverse input order! l1JL, or the priority order may be decided for each type of point or according to various criteria such as priority element type, and the determination may be made based on that order.

FIG. 5 is a diagram for explaining an example of processing when switching elements using a predetermined signal, and FIG. 6 is a diagram for explaining an example of processing when switching input points using a predetermined signal. In this case as well, there is no big difference between the elements and the input points, so an example of the processing when switching elements will be explained with reference to Fig. 5.Up to the switching signal input processing, Since this is the same as FIG. 3, the explanation will be omitted since it will be redundant.

[Phase] Input the transfer signal or confirmation signal. In addition,
In the case of inputting data that already generates a figure, the generated figure is erased by this signal. Next, perform the process (■).

■ Check whether it is a confirmation signal or not. Confirmation can be done by inserting a confirmation input step like this, or by making it recognize that it is continuing by receiving a repeated signal again, and when the next step is input, it is the same as if there was a confirmation signal as if there was no mistake. The determination may be made as follows.

If YES, @ processing is performed, and if NO, 0 processing is performed.

■ Confirm search elements. Note that a setting input may be provided to turn on/off the transfer and confirmation functions at the time of pick element recognition.

■ Identify the following elements. Next, process ① and ②.

■ Restore the color of the previous search element in the cursor window to its normal color, and display the next identified element in a different color. Next, return to the process of [phase].

[Phase] Return the color of the previous search element on the overall drawing display screen to the normal color, and return to the 0th order [Phase] process of displaying the next specified element in a different color.

FIG. 7 is a diagram for explaining an example of processing when inputting or picking a point or element to be sought in an enlarged drawing within a cursor window. If the input point or pick element displayed in a different color in the enlarged drawing in the cursor window is not what you are looking for, and you want to input or pick the point or element you want in the enlarged drawing in the cursor window, do the following: Perform processing like this.

■ Recognize the cursor window function on signal.

Next, perform the process (■).

■ Set the cursor input position as the enlarged display position. Note that at this point, the element pick or point strength described above may be used. Next, perform the process (■).

This function may always be provided. Also, the third
It is not necessary to switch the display attributes in the entire drawing display area in FIGS. 7 through 7.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, each input is enlarged and displayed at any time in a specific area (cursor window) different from the overall drawing, and details can be input while viewing the overall drawing. Since confirmation can be performed, it becomes easier to confirm the details of the input, and it becomes easier to discover incorrect input. In addition, there is no need to switch between the overall drawing and the enlarged drawing, and there is no need to switch to the entire drawing and enlarge it over a wide area each time an enlarged drawing is required, so the enlargement processing time is shortened.
In addition, detailed input can be made in short steps. Furthermore, even completely overlapping elements can be checked by displaying them in different colors by switching between them.
