2. Description of the Related Art CAD (computer-assisted design)
When a drawing is created, a lot of operations are performed to rotate and arrange one part at a certain angle. On the other hand, the direction of the attribute of the rotated part is usually horizontal writing, and if the part is simply rotated, the graphic and the attribute may overlap, and the attribute may overlap. In such a case, the CAD operator has corrected the position of the attribute.

As a method for reducing such correction of the position of the attribute, there is known an image data rotation method described in Japanese Patent Application Laid-Open No. 62-206677. In this image data rotation method, during the rotation processing, the rotation processing is performed while maintaining the positional relationship between the coordinates related to the figure and the center coordinates of the character closest to the figure, and the character is related to the figure. The correction is made so as not to overlap with the coordinates. Then, the character is displayed at the position of the obtained character coordinate without changing the character direction. That is, the character data does not change the character display direction and moves in parallel with the rotated figure. Thus, the character does not rotate, and the figure and the character do not overlap.

Here, "parts", "graphics", "attributes", "part attributes",
The terms "pin attribute", "part pin", "connection line", and "segment area" are defined.

"Parts" are symbols such as electrical diagram symbols. The “graphic” is a graphic part other than the character string in the parts. “Attribute” refers to each character string other than a figure. The “part attribute” is a character string that describes the type and function of the entire part.
"Pin attribute" is a character string that describes the function of a pin of a part. Here, an example of the parts is shown in FIG.
-(C), "figure", "attribute", "part attribute"
FIG. 3 shows an example of the “pin attribute”.

In the example shown in FIG. 3, a portion indicated by reference numeral 100 (portion surrounded by a dotted line) indicates a "part", and a portion indicated by reference numeral 110 (portion surrounded by a dotted line). "Graphic", and reference numerals 121, 1
The part indicated by 22 indicates “attribute”. In the attribute, a portion indicated by reference numeral 121, for example, “NFB”,
The character strings "KN", "KT", "Z", and "AT" indicate "part attributes", while portions indicated by reference numeral 122, for example, "1", "2", "3", "4". Character string (number)
Indicates a “pin attribute”. Note that information on whether the attribute is a part attribute or a pin attribute is added to the attributes 121 and 122 attached to the part 100. In the case of the pin attribute 122, it is assumed that the pin attribute of the figure is already defined.

A "part pin" is a point at which a part can be connected to a connection line.
Is a line connecting a pin of a certain part and a pin of another part, or a line connecting connection lines. Here, an example of “part pins” and “connection lines” is shown in FIG.
Shown in In FIG. 4, the portion indicated by reference numeral 130 (see the symbol “x”) indicates “part pins” and the reference numeral 1

By the way, the part 10 as shown in FIG.
0, ie, figure 110 and attribute (ie, character string) 1
Data indicating 21 and 122, pin 1 as shown in FIG.
Data indicating the connection line 30 and the connection line 140 is stored in the auxiliary storage device 12, and is loaded into the main storage device 13 during a graphic editing process.

The graphic editing process performed by the symbol rotating device having such a configuration will be described. First, a user such as a graphic editor operates, for example, the keyboard 30 or the mouse 40 to select, for example, an icon or a menu for starting the graphic editing editor displayed on the display device 20.
A command to start the graphic editing editor is input, and a part name to be edited in the part names displayed on the display device 20 is designated (or selected). These command data and data indicating the name of the part to be edited are input to the CPU 11 via the input / output control unit 14.

The CPU 11 performs the following based on the input data.
A graphic editing editor (including a program indicating a rotation processing procedure to be described later) stored in the auxiliary storage device 12 is read into the main storage device 13 and activated, and a part name to be edited stored in the auxiliary storage device 12 is stored. Is read into the main storage device 13. And
The CPU 11 performs a rotation process on the part to be edited by executing the graphic editing editor.

Next, rotation processing by the CPU 11 of the symbol rotation device will be described with reference to FIG. FIG.
Is a flowchart showing the rotation processing procedure.

Here, a rotation process for rotating a part by X degrees will be described. In this rotation process, the data of the graphic editing editor and the part to be edited are transferred from the auxiliary storage device 12 to the main storage device by the CPU 11. 13 is read.

The CPU 11 classifies the attributes of the parts read into the main storage device 13 into two types, "part attributes" and "pin attributes", based on information added to the parts. Here, an example of the read parts is shown in FIG. In the example shown in FIG. 8, "PINa",
Each character string of “MEMO” and “PIN2” is a pin attribute, and other attributes such as “PARTS” and “NF”
Character strings such as "B" and "NFB22" are part attributes. The pin attribute of “PINa” and “MEMO” is a character string related to the pin A at point A in FIG. 8, while the pin attribute of “PIN2” is the pin B at point B in FIG. Is a character string related to

Next, the CPU 11 obtains a segment area for each attribute (character string) for the read part (step S11), and obtains a graphic segment area (step S12). Here, an example of a segment area for each attribute (character string) obtained is shown in FIG. In this example, a segment area of each part attribute indicated by reference numerals 201 to 209 and a segment area of each pin attribute indicated by reference numerals 210 to 212 are obtained. This figure 9
In the example shown in FIG.
FIG. 10 shows how 0 is obtained. In FIG. 10, reference numerals 201 to 212 are omitted.

Note that the symbol "x" in FIGS. 9 and 10 is not a figure but a mark written to clearly indicate a pin in explaining this rotation processing, and is a part of an actual figure. is not. For this reason, they are ignored when obtaining the segment area.

Subsequently, the CPU 11 extends each side of the segment area 220 obtained in step S12, and
As shown in FIG.
Is divided into two areas (step S13), and further, each of the part attribute and the pin attribute is grouped (step S14), and the grouped attribute (character string)
Is obtained for the segment area (step S15).

At the time of this grouping, regarding the part attribute, for each region obtained in step S13,
The attributes (character strings) in the same area are grouped. At this time, if the part attribute extends over a plurality of areas, the area where the segment area of the part attribute overlaps the largest is regarded as the area to which the part attribute belongs. On the other hand, regarding the pin attributes, attributes belonging to the same pin (character strings) are grouped. FIG. 12 shows the result of the grouping in this manner.

In the example shown in FIG.
The part attributes of the segment areas 1 and 202 (see FIG. 9) are grouped, and a rectangular (rectangular) segment area 23 is defined for the grouped attributes.
One is required. Similarly, reference numeral 203 and reference numeral 2
The part attributes of each of the segment areas 04 are grouped, and the segment area 232 is determined for those attributes. Similarly, the part attributes of the segment areas denoted by reference numerals 205 to 208 are grouped, and the segment area 233 is obtained for those attributes.
Further, the pin attributes of the segment areas denoted by reference numerals 210 and 211 are grouped, and the segment area 234 is determined for those attributes.

Next, as shown in FIG. 13, the CPU 11 executes step S12 for the entire part shown in FIG.
The image is rotated by X degrees about the center point of the segment area 220 of the figure obtained in (step S16). Here, it is assumed that X is rotated 90 degrees in a counterclockwise (counterclockwise) direction.

Subsequently, the CPU 11 determines the attribute or attribute group from the state of the parts shown in FIG.
As shown in FIG. 4, the rotation is performed by (−X) degrees about the center point of each segment area (step S17). Here, X is rotated 90 degrees clockwise (clockwise). Of course, in the counterclockwise (counterclockwise) direction, "360-
X (= 90) "= 270 degrees.

Finally, the CPU 11 corrects the overlapping of the attributes after rotation with respect to the state of the parts shown in FIG. 15 (the same state as the parts shown in FIG. 14) (step S1).
8). The details of this correction processing will be described later, but will be briefly described here.

First, the state of the part shown in FIG. 15 (the same state as the part shown in FIG. 14) is changed to the state of the part shown in FIG. 16 by correcting the overlap between the pin attribute and the figure. That is, the segment area 212 that has overlapped with the segment area 220 of the figure has been moved to a position that does not overlap with the segment area 220.

When the overlap between the pin attributes is corrected from this state, the state of the part shown in FIG. 16 changes to the state of the part shown in FIG. That is, the segment area 212 and the segment area 231 that have overlapped each other
Indicates that the segment area 231 has been moved to a predetermined position,
It does not overlap.

Further, when the overlap between the part attribute and the figure is corrected from this state, the state of the part shown in FIG. 17 changes to the state of the part shown in FIG. That is, the segment area 220 and the segment area 233 that have overlapped each other are in a state where the segment area 233 is moved to a predetermined position and do not overlap.

In the first embodiment, the pin attribute or the pin attribute group is managed by an array in which the pins of the figure to which the pin belongs are indexed. For example, pin 1
4 is in an arrangement relationship as shown in FIG. 19A, the values of pins 1 to 4 are used as indices, and an array 250 in which attribute values (that is, pin attributes of pins) are registered. I do. In this case, the pin attribute array 250 includes an index 251 and an attribute value 252. Therefore, even if the CPU 11 creates the pin attribute array 250 as shown in FIG. 19B in the main storage device 13 before rotating the part, even if the CPU 11 rotates the part at a predetermined angle, The relationship between the pin and the pin attribute (attribute value) can be recognized.

The part attribute or the part attribute group is managed by an array in which the area to which the part belongs is indexed. For example, the regions 1 to 8 correspond to those shown in FIG.
In the case where it is assumed that there is an arrangement relationship as shown in FIG. 8, the array 260 in which attribute values (part attributes belonging to the area) are registered using each value of the areas 1 to 8 as an index. In this case, the part attribute array 260 has the index 261
And an attribute value 262. Therefore, C
The PU 11 creates an array 260 of part attributes as shown in FIG. 20B in the main storage device 13 before the rotation of the part, so that even if the rotation processing is performed at a predetermined angle with respect to the part, the area The relationship with the part attribute (attribute value) belonging to the area can be recognized.

Next, the process of correcting the overlap of attributes after rotation in step S18 will be described in detail.

In this correction processing, the position of the attribute is corrected in the order of the following steps S18-1 to S18-5 in order to eliminate the overlap between the attributes or the figure and the attribute with respect to the rotated part. Steps S18-1 to S18-1
Each process of 18-5 is included in the process of step S18. Therefore, each of these steps S18-1
A program indicating a rotation processing procedure (see FIG. 7) including the processing procedures of S18-5 is stored (recorded) in the auxiliary storage device 12 as a computer-readable recording medium.

Step S18-1 (Correction of overlap between "pin attribute" and "graphic") This correction is performed, as shown in FIG.
In the case where the segment areas 321 and 322 having the pin attribute overlap each other, the segment area 321 and the segment area 322 are moved so that the “pin attribute” and the “figure” do not overlap. It is.
When a single pin attribute overlaps a figure, the pin attribute is moved.

More specifically, the CPU 11 defines the number of pins in the figure as N, and repeats the following processing from i = 1 to N. That is, when the segment area of the pin attribute of the pin i or the pin attribute group in the figure overlaps the segment area of the figure, the pin attributes are moved so that the distance between them becomes equal to the distance before rotation. In this case, the position is moved in the direction opposite to the direction in which the figure exists.

For example, as shown in FIG. 22A, the segment area 310 of the figure before rotation and the “PIN
The segment area 321 having the pin attribute “2” is “t1”.
If the segment area 310 of the figure and the segment area 321 of the pin attribute of “PIN2” overlap as shown in FIG. 22B after rotation and before correction as shown in FIG. As shown in FIG. 22C, the segment area 321 having the pin attribute “PIN2”
Are moved in the opposite direction (to the left in FIG. 22 (c)) to the figure (segment area) so that the distance between the segment areas is equal to the distance t1 before rotation.

Step S18-2 (Correction of Overlap between "Pin Attribute" and "Pin Attribute") This correction is performed, as shown in FIG. Although separated from the segment areas 321 and 322, the two segment areas 321 and
When the pins 322 overlap each other, any one of the pin attributes is moved so that the “pin attributes” do not overlap.

More specifically, the CPU 11 defines the number of pins in the figure as N, and repeats the following processing from i = 1 to N. In other words, when the pin attribute of the pin i or the segment area of the group of the pin attribute in the figure overlaps the segment area of the pin attribute or the group of the pin attribute of the pin (i-1) in the figure, the distance between the pins before the rotation The position of the former is moved so as to be equal to the distance of. in this case,
The position is moved in the direction opposite to the direction in which the figure exists.

For example, as shown in FIG. 24A, a segment area 321 having a pin attribute of “PIN1” before rotation is provided.
And segment area 3 with pin attribute of “PIN2” before rotation
22 are arranged with a distance of “t2” (in this case, t2 = 0), and after rotation and before correction, as shown in FIG. 24B, a segment having a pin attribute of “PIN1” When the area 321 and the segment area 322 of the pin attribute of “PIN2” overlap, as shown in FIG. 24C, the segment area 321 of the pin attribute of “PIN2” is shifted by a distance between the segment areas before rotation. Is moved in the opposite direction (to the left in FIG. 24C) to the figure (segment area) so as to be equal to the distance t2.

Step S18-3 (Correction of Overlap between "Parts Attribute" and "Figure") This correction is performed by, as shown in FIG. 25, a segment area 310 of the figure and a segment having a plurality of (for example, two) parts attributes. When the regions 331 and 332 overlap, the segment region 331 and the segment region 332 are moved so that the “part attribute” and the “graphic” do not overlap. When a single part attribute overlaps a figure,
Move the part attribute.

More specifically, the CPU 11 defines the number of areas as “8” and repeats the next processing until j = 1 to 8. That is, when the segment area of the part attribute belonging to the area j or the segment area of the group of the part attribute overlaps the segment area of the graphic, the position of the part attribute is moved so that the distance between them becomes equal to the distance before rotation. In this case, the position is moved in the direction opposite to the direction in which the figure exists.

For example, as shown in FIG. 26A, when the segment area 310 of the figure before rotation and the segment area 331 of the “part attribute” before rotation are arranged with a distance of “t3”. When the segment area 310 of the graphic overlaps the segment area 331 of the “part attribute” as shown in FIG. 26B after the rotation and before the correction, as shown in FIG. The segment area 331 of “attribute” is moved in the opposite direction (left direction in FIG. 26C) to the (segment area) so that the distance between the segment areas is equal to the distance t3 before rotation.

Step S18-4 (Correction of Overlap between "Pin Attribute" and "Part Attribute") As shown in FIG. 27, this correction is performed by using the segment area 310 of the figure, the segment area 321 of the pin attribute, and the part attribute. By moving the part attribute when the segment area 321 of the pin attribute and the segment area 331 of the part attribute overlap with each other, while being separated from the segment area 331, the “pin attribute” and the “part attribute” are changed. This is to avoid duplication.

More specifically, the CPU 11 defines the number of areas as “8” and repeats the next processing until j = 1 to 8. That is, in the repetitive processing for each area,
Further, the number of pins in the figure is defined as N, and i = 1 to N
Repeat the following process until That is, if the segment area of the part attribute or the group area of the part attribute group belonging to the area j is overlapped with the segment area of the pin attribute or the group of the pin attribute of the pin i in the graphic, the distance between the segment area of the graphic Move the former so that is equal to the distance before rotation. In this case, the position is moved in the direction opposite to the direction in which the figure exists.

Step S18-5 (Correction of overlap between "parts attribute" and "parts attribute")
As shown in the figure, the segment area 310 of the figure and the segment areas 331, 3 of plural (for example, two) part attributes
32, but when the segment area 331 of the part attribute overlaps the segment area 332 of the part attribute, any one of the part attributes is moved so that the “part attributes” do not overlap with each other. It is for doing.

More specifically, the CPU 11 defines the number of areas as “8” and repeats the following processing until j = 1 to 8. That is, in the repetitive processing for each area,
Further, the number of pins in the figure is defined as N, and i = 1 to N
Repeat the following process until That is, when the segment regions of the part attribute belonging to the region j or the segment regions of the group of the part attribute overlap, any one of the attributes is moved so that the distance between them becomes equal to the distance before rotation. In this case, the position is moved in the direction opposite to the direction in which the figure exists.

Here, the correction of the overlap between the “pin attribute” and the “part attribute” and the “part attribute” and the “part attribute”
The correction of the overlap will be described with a specific example.

For example, as shown in FIG. 29A, a segment area 321 having a pin attribute of “PIN1” before rotation is provided.
And the segment area 331 of the part attribute of “part attribute 1” before rotation is arranged with a distance of “t4”, and the segment area 331 of the part attribute of “part attribute 1” before rotation and the segment area 331 of “part attribute 1” before rotation. Assume that the part attribute 2 and the segment area 332 of the part attribute 2 are arranged at a distance of “t5”.

Then, after the rotation and before the correction, as shown in FIG. 29B, the segment area 321 of the pin attribute of “PIN1” and the segment area 331 of the part attribute of “Parts attribute 1” are overlapped. When the segment area 331 of the part attribute of “part attribute 1” and the segment area 332 of the part attribute of “part attribute 2” overlap, first, as shown in FIG. The segment area 331 is moved in the opposite direction (to the left in FIG. 29 (c)) to the figure (segment area) such that the distance between the segment area 331 and the “PIN1” segment area 321 becomes equal to the distance t4 before rotation. Let it.

In the state of the parts shown in FIG. 29C, the segment area 3 of the "part attribute 1" is still
31 and the segment area 332 of “part attribute 2” overlap, in such a case, as shown in FIG. 29D, the segment area 332 of “part attribute 2”
Are moved in the opposite direction (left direction in FIG. 29D) from the figure (segment region) so that the distance between the segment regions becomes equal to the distance t5 before rotation.

FIGS. 30 and 31 show examples of parts when the rotation processing is performed according to the above-described rotation processing procedure.
In the example shown in FIG. 30, the part 410 before rotation is rotated 90 degrees counterclockwise to be in the state of the part 410A. Also, in the example shown in FIG. 31, the part 420 before rotation is rotated 90 degrees counterclockwise to become a part 420A, and the part 420A is rotated 180 degrees counterclockwise to turn the part 420B. And the part 420B is moved counterclockwise by 2
The part 420C is rotated 70 degrees (or 90 degrees clockwise).
