Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a data processing device such as a CAD system, and in particular, it processes input data in various ways to process complex data such as blueprints, etc. The present invention relates to a data processing device suitable for creating data by making mistakes.

[Prior Art] In conventional CAD systems, when operating a geometric model stored in a storage device and displayed on a screen, for example, a certain curve, there are only two possibilities for that curve: ``exists'' and ``does not exist.'' , its operation was also simple. For example, when executing a deletion command, there are only two options: ``Delete'' and ``Do not delete.'' If the operator selects ``Delete,'' the curve data will also be deleted from the storage device and cannot be restored. Therefore, for example, JP-A-62-115
In the conventional technology described in Publication No. 575, when "Delete" is selected, only the display is first deleted, the operator is asked whether "Delete is possible", and "Delete is allowed" is inputted before the display is deleted from the storage device. I am trying to delete curve data.

[Problems to be Solved by the Invention] In recent years, there has been a movement to use CAD systems created for detailed design also in planning design, which is an upstream process of design.

At this time, the drawing methods for detailed design and planned design are different, so the conventional method has the following problems.

Users of conventional CAD systems are more likely to be relatively inexperienced designers or full-time operators than veteran designers. Their main task is to input parts drawings and assembly drawings into a CAD system based on plans drawn on paper by veteran designers.

Here, the technique of copying the model accurately, quickly and neatly, or in other words, inputting it, is required. Therefore, the lines they draw on their CRT screens, even if they are for drawing, are already fixed and are unlikely to be changed significantly.

However, in more upstream planning and design, you study the structure and mechanism of the machine while drawing the plans, and as you draw various drawings yourself, things that were vague in your head gradually become clearer. This means that it will continue to solidify. In this case, the position and length of the lines are mixed, with some being required to be there and others being decided temporarily.

For example, in actual design, from the initial stage of the design to the end of the design, the decision as to whether or not to use a certain part depends on the circumstances of the surrounding design, etc. It is normal for it to sway slightly inside.

In addition, when designing the shape, there will be a mixture of parts that have almost been decided and parts that are still in a tentative state.
In traditional paper-and-pencil designs, this difference could be adjusted by adjusting the strength with which the pencil lines were drawn. In other words, the parts that have been decided can be written darker, and the parts that have not been decided can be written lighter.

However, in conventional CAD systems, the presence and shape of a part can only be in two states: presence or absence. Therefore, if the shape data of a certain part is about to be determined and is deleted due to an erroneous operation or misrecognition, it cannot be restored and must be re-entered. This not only interrupts design thinking, but also irritates designers.
This will significantly reduce design efficiency.

An object of the present invention is to provide an easy-to-use image creation method that matches the human drawing sense, and a data processing device such as a CAD system using the method.

[Means for solving the problem] The above purpose is to add attached information indicating the "degree of certainty" to data such as a shape model, change this "degree of certainty" according to operations, etc., and perform operations on the data. This is achieved by differentiating the processing content of the operation command based on the "determinacy" of the data, and when outputting data, changing the output form depending on the "determinacy" of the data.

[Operation] For example, when a deletion command is executed for a certain curve, if the "degree of certainty" of the curve is lower than a predetermined threshold, the display of the curve is erased and the data of the curve in the storage device is also deleted. However, if the "degree of certainty" is high, the "degree of certainty" of the attached information is reduced without deleting the curve data in the storage device. At this time, the display may be erased or dimmed, and when moving a certain curve with a movement command, the curve will be moved more if its "certainty" is higher than the threshold than if it is lower. For example, make the movement of the mouse cursor slower. Furthermore.

When displaying on a screen, as the "degree of certainty" increases, colors are displayed, lines are made thicker, display brightness is increased, etc.

The "degree of certainty" of data such as text data such as shape models and documents includes the degree of certainty of whether the data exists, the degree of certainty of the shape of the shape model, the degree of certainty of the position of the data, and the degree of certainty of the data's position. The degree of certainty of the size of the model, the degree of certainty of the dimensions of the data placement position, the degree of certainty of its dimensions, the degree of certainty of the viewing direction and origin position of the drawing view, the degree of certainty of the component configuration in the blueprint, the degree of certainty of the origin position of the parts Possible factors include certainty.

In addition, means for outputting "determinacy" according to the degree of certainty is such that if the data is a character, the brightness of the character or line if it is a shape model is increased as the degree of certainty is higher, or by color separation. is displayed. In addition, if it is a shape model, the type of line is a solid line or a 9-dot line depending on the degree of certainty.

Make it a broken line, chain line, or change the thickness of the line. Alternatively, the display information of the surface of the shape model is changed depending on the degree of certainty. For example, change the display color of the surface or change the filling pattern of the surface. Furthermore, when attempting to manipulate the layout of a shape model or text, a shape model or text with a high degree of certainty makes it difficult to manipulate.

For example, when moving the cursor, the moving speed of the cursor that instructs the movement is slowed down. Alternatively, when performing an operation on data with a high degree of certainty, the display of that data is blinked, or the blinking speed is changed depending on the degree of certainty.

Alternatively, the "certainty" of the data may be displayed numerically on the screen. Furthermore, it sounds a buzzer and changes the background color of the display window.

Methods for increasing or decreasing the "certainty" include preparing a dedicated command and having the user directly increase or decrease the degree of certainty, or automatically adjusting the data when an operation is performed on the data, depending on the type of operation. For example, there is a way to automatically increase or decrease the "degree of certainty".

When an operation is performed to define the arrangement position of certain data from the reference origin by dimensions, etc., the degree of certainty of that data is increased, and when the data is moved, the degree of certainty is decreased. Alternatively, when the data IJ is referred to and an operation such as copying is performed, the degree of certainty of the data Lj is increased, and if a deletion operation is performed, the degree of certainty is decreased. Also,
When an operation on data is instructed to be input from a keyboard, the degree of certainty is made high, and when an input instruction is given from a mouse, the degree of certainty is made lower than that for keyboard input. That is, keyboard, mouse, dial light pen,
Change the degree of certainty and increase/decrease for each input device such as a tablet or stylus pen. Furthermore, if certain data is input and no operations are performed on that data for a long time, the degree of certainty of that data increases, and if the number of operations, for example the number of movements, for certain data increases, the "position"
The degree of certainty of the data becomes lower, but the degree of certainty of the "existence" of that data is increased.

The means for differentiating the contents of the processing of the operation command according to the "degree of certainty" may, for example, differentiate the executable operations themselves.

For example, if the degree of certainty of the design is high, execution of deletion is restricted.

In addition, the operation target is differentiated. For example, if the degree of certainty of the "position" is high, restrictions are placed on movement processing. Furthermore, when selecting a target for operation, priority is given according to the degree of certainty. Alternatively, the person operating the data processing device is made to input an identification number, and the identification number is used to prevent a beginner from operating data with a high degree of certainty. Alternatively, data with a high degree of certainty cannot be manipulated at times when it is easy to manipulate the data incorrectly, such as late at night.

Alternatively, since errors are more likely to occur as the operation time becomes longer, the longer the operation time, the more difficult it is to manipulate data with a high degree of certainty, or the message may be output.

Furthermore, in systems that take the form of distributed processing or LAN,
Data with a high degree of certainty can only be manipulated from a specific terminal.

[Example] Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

As an example, let's consider the design of the paper feed section of a computer printer. FIG. 3 shows a gear train 101, 102, 103, which transmits the power of the motor 100 to the paper feed roller 105,
This shows a two-dimensional examination of 104.

It is assumed that the number of teeth and pitch circle diameter of each gear have already been determined through preliminary design calculations. Note that a pitch circle, which is a typical shape, is used here to represent a gear.

First, four gears 101 to 104 and the motor 100 are temporarily arranged as shown in FIG. In this example, each part and line segment has design confirmation such as the degree of “existence”, “shape”, “position”, and “size”. The degree is held as attribute data of each CAD data. The degree of certainty, that is, the degree of certainty, is set to an initial value of 0, for example, and as the design progresses and ambiguity is eliminated, this degree of certainty increases,
The number decreases when a defect is discovered and the design has to be revised.

The designer is made to be able to recognize this increase/decrease as display information of the lines forming the shape model.

For example, it can be displayed on a CRT screen such that the thicker the line, the higher the degree of certainty, and the thinner the line, the lower the degree of certainty. Another way to make the designer aware of the difference in certainty is to change the type of line in the geometric model (solid line, dashed line, one-dot line, etc.).
) method, method using line density (brightness when displaying) method, method to differentiate by line color, method to output as feedback information to operating equipment when trying to manipulate a shape model, method for designers. There are methods of outputting it as image information, methods of outputting it as sensory information to the designer, etc.

In the case of Fig. 3, the degree of certainty of the "position" of each gear 100 to 104 is low, and since some of the gears may disappear due to design changes, the degree of certainty of the "existence" of each gear is also low. , so the "shape" of the gear is all shown as a thin line. Figure 4 shows a state in which the study has progressed to some extent, with the shape model indicated by the thick line (in Figure 4, the motor
100 and gear 101) indicate that the degree of certainty of "existence" is high.

For example, by defining the dimensions between the gear 101 and the line segment 106 as a reference line, the degree of certainty of the vertical "position" of the gear 101 is increased. As the degree of certainty of "position" increases, the degree of certainty of "existence" also increases. However, “existence”
Just because the degree of certainty of is high does not necessarily mean that the degree of certainty of "position" is high. For example, even if you have decided from the beginning that you will absolutely use this part and the degree of certainty of its ``existence'' is high, the degree of certainty of its ``position'' is low if you are not sure where to place it.

As means for increasing or decreasing the degree of certainty, for example, in addition to means for indirectly increasing or decreasing the degree of certainty depending on the type of operation performed with reference to the shape model (for example, the degree of certainty increases when it is referred to during copying), You can increase or decrease the degree of certainty directly by using a dedicated command (for example, by inputting the degree of certainty as a numerical value), or indirectly by the type of operation performed on the shape model (for example, by using the definition The degree of certainty increases when deletion is performed, and decreases when deletion is performed.

), means to increase or decrease depending on the type of equipment used when operating the shape model (for example, "points" input from the keyboard have a high degree of certainty, and "points" input from the mouse have a high degree of certainty). (low), means to increase or decrease depending on the existence time of the shape model after it was created (for example, when the shape is not changed by the operator for a long time, the degree of certainty becomes high), operations performed on the shape model There are means for increasing and decreasing the number of operations based on the number of operations performed with reference to the shape model, and means for increasing and decreasing the number of operations based on the number of operations performed with reference to the shape model.

FIG. 5 shows a three-dimensional examination of the gear train. Even if it seems to go well in two-dimensional examination,
This is because when examined in three dimensions, it may actually be that they are interfering. Suppose now that the gear 103 is found to be interfering with other parts. In order to avoid interference, the designer will move the position of the interfering parts or change the shape of the parts. Changing the shape of a part may mean adopting a different part. Therefore, the designer modifies the area around the gear 103, but in the conventional method, it was often moved or deleted. The problem with erasing something is that nothing remains behind, making it difficult to redesign.

In conventional paper-and-pencil designs, it is common to write strongly and darkly in areas where the degree of certainty of existence is high, and these areas differ from other areas where the degree of certainty is low. By doing this, even if you find a defect in the surrounding design and erase it with an eraser in order to redo it, the pencil mark remains in the areas where there is a high degree of certainty of ``existence'' written strongly and darkly, so it remains behind. Using lines makes it easy to modify the design. However, conventional CAD systems were not easy to use because they completely ignored the human tendency to write darkly in areas with a high degree of certainty.

However, in this embodiment, using a command similar to deletion described later, even if the display is erased to selectively leave only those areas where the design is advanced and the degree of certainty of "existence" is high, the data in the memory will remain. I'll keep it. ), all areas with low certainty (even in memory) can be used to remove :s4, so the same thing as with a piece of paper and a pencil can be achieved.

The effect of this is that the finalized part of the design is not erased, so the design can be redone efficiently.

A similar function is to store a sequence of command operations in chronological order and cancel the execution of each operation one by one. This feature allows you to undo incorrect operations in sequence.

However, with this function, if an operation has been performed relatively recently on a part where the certainty of "existence" is high, that operation will also be canceled, so the operation performed on the part with a high certainty of "existence" will be wasted. The problem is that it becomes

Here, we have shown an example of distinguishing the deletion target in commands similar to deletion as a means of distinguishing the processing contents of operation commands based on the difference in certainty, but there are also other ways to distinguish the executable operations themselves. It is possible to distinguish between priorities for selection as an operation target, distinguish between targets to be referred to during an operation, distinguish the range of influence of an operation, distinguish between operators, distinguish the operation time, and distinguish between operations. It is also possible to distinguish time and operation location.

FIG. 1 is a PAD showing an example of a processing procedure for an operation similar to deletion in which a shape model has a certainty of existence j as a design certainty, and FIG. 2 is a PAD according to this embodiment. CA
It is a block diagram of D system.

In FIG. 2, reference numeral 1 denotes an input device consisting of a keyboard, mouse, tablet, stylus pen, etc., through which an operator inputs graphic information, etc. The device control device 3, which is composed of a memory, a magnetic disk, etc., processes the information given from the input device 1 and the storage device 2 using a program stored in the storage device 2, and creates a shape model. Define or change. The output device 4 outputs this state to an output device such as a CRT display, plotter, or printer.

Next, the operation of each part in FIG. 2 will be explained based on the PAD in FIG. 1.

First, when a deletion command is selected from the operation menu (step toooo), the control device 3 selects the deletion target (1
001) to the designer. When the designer inputs a deletion target from the input device 1, the control device 3 refers to the degree of certainty of the “existence” of the selected shape model from the storage device 2 (1.
002). Deletion processing is distinguished based on this degree of certainty (1003).

If the degree of certainty of “existence” is high (1004), the control device 3
Confirm with the designer whether you really want to delete it (1005).
When the designer approves (1006), the shape model to be deleted is deleted from the storage device 2 (1007), and the corresponding shape model is deleted from the appearance bag M3 (1008). If the designer denies deletion (1009), the control device 3
lowers the degree of certainty of the shape model in the storage device 2 (IO
IO), and on the output device 3, the display width of the line is made thinner (
1011).

If the degree of certainty of “existence” is low (1012), the control device 3
deletes the shape model to be deleted from the storage device 2 without asking the designer for confirmation (1013), and erases the corresponding shape model from the output device 3 (1014).

According to this embodiment, it is possible to prevent a shape model whose degree of certainty has become high after repeated examinations from being mistakenly deleted. Then, by executing the delete command, it is possible to reuse lines whose certainty level has been lowered, and design changes can be easily made.

Next, another embodiment of the present invention will be described in detail.

FIG. 6 is a PAD showing an example of a processing procedure when a shape model has "position" certainty as the design certainty and the processing contents of movement operations are distinguished.

When the degree of certainty of “position” is high (2004), the control device 3
(2005)
When the designer approves (2006), the shape model to be moved is moved in the storage device 2 (2007), and the degree of certainty of the IJ of the shape model data is lowered (2007).

displays the state in which the “position” and line width of the corresponding shape model have been changed (2010). When the designer denies movement (2011), the control device 3 increases the degree of certainty of the shape model data in the storage device W2 (2012),
Increase line width (2013). The width of the display line is also increased in the exit bag W3 (2014).

If the degree of certainty of “position” is low (2015), control device 3
moves the shape model to be moved in the storage device 2 without asking the designer for confirmation (2016), and lowers the certainty of the "position" of the shape model data in the storage device 2 (2016).
17) Make the line width thinner (2018). Output device 3
Now, change the display "position" of the corresponding shape model and narrow the width of the display line (20.19).

According to this embodiment, it is possible to prevent erroneously moving a shape model whose position IEJ has a high degree of certainty after careful consideration. Since it can be moved freely, it has the effect of interrupting the designer's thinking.

〔Effect of the invention〕

According to the present invention, since the content of the operation is differentiated depending on the degree of certainty of the design, it is possible to prevent mistakes in the final stage of the design, and it is possible to operate freely in the early stage of the design, which is convenient for the designer. Improves operability.
