DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording medium for creating drawings and an apparatus for creating drawings.

[0002]

2. Description of the Related Art For example, as a design drawing, there is a drawing for temporary material arrangement planning shown in FIG. 7 in which scaffolding materials are arranged along the outer periphery of a building. When such a scaffold drawing 51 is drawn, it is common to use a two-dimensionally displayed plan view 53 or elevation view 54 of a building 52 and arrange scaffolding materials 55 on each drawing. . Therefore, it is necessary to draw a plan view 53 and an elevation view 54 of the building 52 first.
However, when using two-dimensional CAD software, the plan view 53,
It is very troublesome because the elevation views 54 must be individually drawn, and the plan view 53 and the elevation views 54 or the elevation views 54 need to correspond to each other. Therefore,
One drawing (building) consisting of three-dimensional data is drawn from the building drawing using three-dimensional CAD software, and the three-dimensional building is displayed on the screen in a coordinate axis system viewed from the X-axis direction, the Y-axis direction, and the Z-axis direction. By displaying, apparently, a two-dimensional plan view and an elevation view can be created. Using this method, the plan view 53 and the elevation view 5 of the building 52 can be efficiently and easily obtained.
4 can be plotted.

[0003]

However, in the plan view 53 and the elevation view 54 of the building 52 created based on the three-dimensionally displayed building data, the display plane coordinate axes are different only by changing the viewing direction (axis). Since each drawing differs from one drawing to another, the drawings 53 and 54 must be saved in individual files.
Therefore, when displayed on a screen such as a display,
Since the drawings 53 and 54 are displayed on different windows, there is a problem that the scaffold drawing 51 cannot be efficiently drawn.

[0004] Further, since the files are different for each of the drawings 53 and 54, the drawings 53 and 54 are not related to each other. For example, when changing various settings such as a magnification and a line type, it is inevitable to set each file. Further, for example, when a building drawing of the plan view 53 is corrected, if a program for reflecting the corrected content on another standing drawing 54 is created, the drawing efficiency can be improved. In this case, it is necessary to associate the data of the drawings 53 and 54 with each other. However, there is a problem that the association between different files requires a complicated program. Further, when printing the created drawings, if the files are different for each of the drawings 53 and 54, there is a problem that it takes time to arrange the files on the same paper.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to arrange a predetermined drawing out of six views on the same coordinate axis even when a method using a three-dimensional drawing is employed. Accordingly, it is an object of the present invention to provide a recording medium for drawing creation and a drawing creation device capable of easily drawing an efficient drawing.

[0006]

Drawing creation processing procedure for creating drawing data for displaying a surface, and arrangement for arranging the plurality of drawings on the coordinate axes of the display plane so as not to overlap the plurality of drawing data obtained by the drawing creation processing procedure The computer executes a drawing arrangement processing procedure for performing processing and storing the drawing data after the arrangement processing in a storage means, and a display processing procedure for displaying the drawing data stored in the storage means on a screen of a display means. The point is that a program for causing the program to be executed is recorded.

According to the present invention, the coordinate conversion data is read by the coordinate conversion data reading procedure, and the three-dimensional data is subjected to the coordinate axis conversion processing based on the coordinate conversion data by the drawing creation processing procedure. A plurality of types of drawing data arranged above are created.
Then, drawing data arrangement processing was performed by the drawing arrangement processing procedure so that the drawings did not overlap on the display plane coordinate axes, the processed drawing data was stored in the storage means, and each procedure was executed by the display processing procedure. The subsequent drawing data is displayed on the screen. As a result, even if a plurality of drawings are drawn out of the six views of the display object using the three-dimensionally displayed drawings, each drawing is arranged on the same display plane coordinate axis as the reference drawing. Further, since a plurality of types of drawing data can be stored in the same file, a plurality of types of drawings are displayed on the same screen (the same window). Therefore, when adding or modifying each drawing or printing the drawing,
An efficient drawing is drawn.

According to a second aspect of the invention, in the first aspect of the invention, at least one of the plurality of drawings displayed on the screen of the display means by the display processing procedure is input to at least one of the drawings. Correction data corrected by the above is subjected to coordinate conversion processing using correction coordinate conversion data stored in a predetermined storage area prepared for each drawing, and drawing data including the correction data after the coordinate conversion is obtained. The gist of the present invention is to provide a modification reflection processing procedure for performing display processing for displaying on the screen of the display means, thereby reflecting the modification contents added by the input means on another drawing.

According to the present invention, in addition to the operation of the first aspect of the present invention, when at least one of a plurality of drawings is corrected, the correction content is converted using the correction data. By displaying the data by performing a coordinate conversion process, the data is reflected in other drawings, so that it is not necessary to individually correct each drawing.

According to a third aspect of the present invention, in the first or second aspect of the present invention, the drawing creation processing step includes, among the coordinate values of the drawing data subjected to the coordinate conversion processing, the axes not appearing on the screen.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an embodiment in which the present invention is embodied in a storage medium for storing program data for creating a drawing for temporary material placement planning and a drawing creating apparatus.
This will be described with reference to FIG.

As shown in FIG. 6, a drawing creating apparatus 1 includes a personal computer 2, a display 3 as a display means, a keyboard 4 and a mouse 5 as input means, a reading device (hard disk or the like) 6 as reading means, a printer. 7 and the like. The PC body 2 has C
A PU 8 and a memory 9 as storage means are incorporated.
A CD-ROM 10 as a recording medium is set in the reading device 6. The CD-ROM 10 stores various programs, coordinate conversion data, and the like. CPU 8 is C
The program data read from the D-ROM 10 is executed. Data and the like necessary for executing the program data are temporarily stored in the memory 9. The printer 7 prints the created drawing.

Next, the program stored in the CD-ROM 10 will be schematically described. Finally, on the screen placed under the construction environment of the scaffolding drawing, the plan view 12 and the elevation view 1 of the building 11 are placed on a common coordinate axis plane (two-dimensional coordinate axis).
Building drawing 17 where 3 to 16 are arranged (see FIG. 4)
The purpose is to draw

The procedure before drawing the building drawing 17 is performed in advance by using three-dimensional software (a program for creating a three-dimensional drawing).
Using the three-dimensional data of the building (display target) 11 that is three-dimensionally displayed as shown in FIG. 5 and executed by the program data, a plurality of two-dimensional drawings 12 are created based on the three-dimensional drawing data. A building drawing 17 consisting of the numbers 16 to 16 is automatically created. The drawing of the three-dimensional drawing is executed by inputting the outline drawing of the building 11 on the screen 3a using the keyboard 4, the mouse 5, and the like. May be used.
In addition, when drawing a three-dimensional drawing, a point view or a line is written on the screen 3a using the mouse 5 or the like, and (x, y) coordinate data is input to create a plan view. This is done by inputting coordinate data (numerical values) in the height direction (z axis).

The operator specifies (sets) which of the six views is to be created, using the mouse 5 or the like, based on the drawn three-dimensional building drawing. In this example, this 3
As a drawing target created based on the three-dimensional drawing, this building 11
(E view in FIG. 5) and four elevation views (A to D views in FIG. 5) are designated. The coordinate axis plane in FIG. 2 is an xy plane, which is a plane when the three-dimensional drawing is viewed from the z direction. In this plane, the three-dimensional drawing is expressed as a plan view.

One of the five drawings 12 to 16 is set as a reference drawing in order to determine the coordinate axis plane of the building drawing 17 composed of one plan view and four elevation views. That is, a plane orthogonal to the direction (viewing direction) that can be viewed as the reference drawing by selecting the viewing direction of the three-dimensional drawing is set as the coordinate axis plane of the building drawing 17. For example, when the reference drawing is the plan view 12 (E view in FIG. 5), the coordinate axis plane is determined by the xy plane, and when the reference drawing is the elevation view 13 (A view in FIG. 5), the coordinate axes are The plane is determined by the xz plane, and when the reference drawing is the elevation view 14 (the B view in FIG. 5), the coordinate axis plane is determined by the yz plane. In this example, the plan view 12 is set as the reference drawing, and therefore, the five drawings 1 constituting the building drawing 17 are shown.
2 to 16 are all created on the xy coordinate axis plane. The three-dimensional drawing data is used as it is for the reference drawing, and in this example, the three-dimensional drawing data is arranged (displayed) on the xy plane to be represented as the plan view 12. That is, the three-dimensional drawing data is copied to the plan view 12 as it is.

The drawing data of the four elevation views 13 to 16 arranged on the same coordinate axes as the plan view 12 designated as the reference drawing are drawn by performing coordinate conversion processing on the three-dimensional drawing data. The coordinate conversion data is data used when a reference drawing is designated and axis conversion is performed so that the coordinate axis component of another drawing becomes the same as the coordinate axis component of the reference drawing. This coordinate conversion data is a CD-
It is stored in a predetermined storage area of the ROM 10. When the reference drawing is the plan view 12, the coordinate axis plane displayed on the screen is the xy axis, and the vertical component is the z axis, and the plan view 12 and the elevation view are arranged so that they can be arranged on the coordinate axes. The drawing data of 13 to 16 is created. Next, screen 3a
By setting the z-axis component not displayed above to “0”, the elevation views 13 to 16 are made two-dimensional, and a scaffolding drawing 17 in which all the drawings are arranged on the same coordinate axis plane is drawn. A conventional scaffolding material (posts, treads, handrails, etc.) is arranged on the building drawing 17 drawn in this way, and FIG.
The scaffold drawing 51 shown in FIG. Note that z in the plan view 12
The axis component may be set to “0” to obtain two-dimensional drawing data.

In the two-dimensional building drawing 17,
Depending on the viewing direction, a line that should be hidden by a display object on the near side is displayed on the screen. Therefore, hidden line processing is performed on the completed two-dimensional building drawing 17. As shown in FIG. 6A, the hidden line processing is to erase the line 18 of the display object M that is hidden by the display object N when the display object N is located in front of the display object M. This is the processing to be performed.

Next, the procedure up to the drawing of the building drawing 17 will be described with reference to the flowcharts of FIGS.
In this example, the reference drawing for coordinate conversion as described above is the plan view 12. When drawing the building drawing 17,
The building drawing drawing routine shown in FIG. 1 and stored in the CD-ROM 10 is executed. At this time, first, the drawing data of the three-dimensional drawing is read and the three-dimensional drawing is displayed on the screen 3a. Next, when the operator selects the drawing button of the building drawing using the mouse 5 or the like, the CPU 8 executes a drawing program.

In step S101, three-dimensional drawing data (three-dimensional CAD data) of the building 11 is read. This drawing data is data having coordinate values of (x, y, z) three-axis components based on a three-dimensional drawing.

In step S102, the coordinate conversion data is read. In this example, since the plan view 12 is selected as the reference drawing, the two axes displayed on the screen 3a are the xy coordinate axes, and the vertical component is the coordinate axis that is the z axis. Therefore, four elevation views 13 corresponding to the views A to D of the building 11 are shown.
The four coordinate transformation data for creating the data Nos. To 16 from the three-dimensional drawing data are (x, y, z) in the A elevation view 13 →
(X, z, -y), (x, y, z) →
(Y, z, x), (x, y, z) →
(-X, z, y), (x, y, z) in D elevation view 16
(-Y, z, -x).

In S103, a coordinate conversion process is performed using the coordinate conversion data read in S102. Then, the coordinate axes (x
Each drawing data is created such that four elevation views 13 to 16 are displayed on the (-y coordinate axis). At this time, the drawing data of the four elevations 13 to 16 are coordinate values in which the plan view 12 and the elevations 13 to 16 overlap each other when viewed from the z-axis direction. This coordinate conversion processing corresponds to a drawing creation processing procedure.

In S104, a drawing arrangement coordinate setting process is executed. This process converts each drawing data into x
This is a process of disposing in the axial direction. That is, in this example, the drawing data of the elevations 13 to 16 are arranged in the x-axis direction in the order of A to D, so that the drawings 12 to 16 do not overlap the x coordinate value of the drawing data. A predetermined coordinate value is added to convert the coordinate data. For example, as shown in FIG. 4, with respect to the plan view 12, each of the elevation views 13 to 16 viewed from A to D respectively has +,
It is set so as to be shifted in the direction, and the values of α to δ are added to each x coordinate value.

In step S105, the coordinate axis component, which is the depth direction as viewed from the screen 3a, is set to "0", thereby
Execute the dimensioning process. In this example, two-dimensionalization is performed by setting z = 0 for the drawing data of the elevation views 13 to 16. Then, since the coordinate data of the z-axis becomes “0”, the drawing data of each of the drawings 13 to 16 becomes two-dimensional data arranged on the xy coordinate axis plane. Also, the plan view 12
Is three-dimensional data having three-axis components. The building drawing 17 is stored in a predetermined storage area as one file.

In step S106, hidden line processing is performed.
At this time, since the drawing data is two-dimensional, the intersection of the lines is necessarily specified. Then, as shown in FIGS. 6B and 6D, assuming that a display object on the front side (front side) is N and a display object on the rear side (depth side) is M on the screen 3a,
When M is completely hidden after N (FIG. 6B)
And part of M or N overlap (FIG. 6D)
In the case of, the line on the rear side is deleted, and when N is displayed entirely on the front side of M (FIG. 6C), both M and N are displayed.

In S107, display processing of the building drawing 17 based on the drawing data after each processing is executed is executed. Then, the building drawing 17 as shown in FIG.
Displayed above.

As described above, the plan view 12 on the same coordinate plane
And a building drawing 17 in which elevations 13 to 16 are arranged. After the building drawing 17 is created,
May have minor modifications. The program is provided with a layer function, and a layer is added when the content of correction is large or complicated. This layer is also a two-dimensional coordinate plane.

When the operator wants to store the correction contents (additional data) in a layer, the operator selects a layer, and the additional data of the correction contents is stored in a layer different from the drawing data. Therefore, if additional data is stored in the layer,
When the three-dimensional drawing is modified and the building drawing 17 is updated using the three-dimensional drawing, the original drawing data is overwritten by the new building drawing 17 and deleted, but the additional data remains in the layer . Therefore, even if the three-dimensional drawing is modified and the drawing data is updated after the additional data is added to the drawing data, the additional data can be used as it is, so that it is not necessary to perform the modification work of adding the additional data again. Become. This configuration corresponds to an additional data storage procedure.

When correcting the drawing data, a line on the screen is selected and designated with the mouse 5 or the like. At this time, for example, if the drawing data is displayed three-dimensionally, FIG.
As shown in FIG. 7, the intersection of the display objects M and N is not specified. Therefore, even if the user tries to select and extract the line 18 shown in FIG. 6A, it is necessary to newly specify the intersection of the display objects M and N, which is troublesome. However, elevation view 1
Since 3 to 16 are displayed in two dimensions, the intersections of the line segments displayed on the screen are automatically specified. Therefore, the line segment can be selected, and the drawing data can be easily corrected.

Also, correction data such as additional data directly added to the drawing data as a separate layer or as it is,
A modification reflection function to be reflected on other drawings is also stored in the program. Then, when the correction data is to be reflected on another drawing, the operator selects a correction reflection execution button displayed on the screen and issues a correction reflection execution command. Then, the operator selects a reflection source drawing with a mouse or the like, inputs a z-axis coordinate value so that the correction data has three-axis component coordinate values, and then selects a reflection destination drawing. Then, the coordinate conversion of the original correction data is executed using the correction coordinate conversion data.

The coordinate conversion data for correction is stored in the CD-ROM 10
Is stored in a predetermined storage area, and the data content is basically based on the same concept as the coordinate conversion data described above. That is, an inverse transformation process of subtracting the coordinate value moved in the x-axis direction in the drawing arrangement process to return to a position overlapping the plan view 12 and then restoring the coordinate axes of the reflection source drawing is performed. Then, after performing the coordinate conversion for converting to the coordinate axes of the drawing of the reflection destination, the contents corresponding to the conversion of shifting in the x-axis direction by a value corresponding to the drawing of the reflection destination are performed at once. In the coordinate conversion data for correction, when the reflection destination is the elevation view 13 to 16, the coordinate value of the z-axis is “0” for two-dimensionalization.

When reflecting the contents of the correction, a correction reflection processing routine shown in FIG. 2 is executed. In S201,
Execute the correction data reading. The correction data is data having three (x, y, z) coordinate values input to the drawing of the reflection source on the screen.

In step S202, the coordinate conversion data for correction is read. The coordinate conversion data for correction has the data content described above. In S203, the correction reflection processing is executed using the coordinate conversion data for correction input in S202. Then, the correction data is reflected on the drawing of the reflection destination.

In S204, a display process for displaying the processing result on the screen is executed. As a result, for example, the correction content input to one drawing displayed on the same plane is reflected on another drawing also arranged on the same plane and displayed on the screen.

Therefore, in this embodiment, the following effects can be obtained. (1) The plan view 12 and the elevation views 13 to 16 are arranged on the same coordinate plane by performing coordinate transformation processing using data of a three-dimensional drawing of a building drawn in three dimensions. It is possible to draw an efficient building drawing 17 that does not require much time for the subsequent work. That is, even if three-dimensional drawing data is used, it is possible to easily obtain a drawing such as a plan drawing and an elevation drawing using two-dimensional CAD software, and each drawing is placed on the same coordinate plane. The drawing time of the building drawing 17 can be reduced.

Further, for example, since the building drawing 17 can be stored in one file, setting such as magnification and line type may be performed for the file, and it is not necessary to perform the setting for each drawing. Is printed on a single sheet of paper, the building drawing 17 may be printed, and the trouble of laying out each drawing can be omitted. Furthermore, since all the drawings 12 to 16 are arranged in one file,
When the drawings 12 to 16 are corrected, there is no need to open a file for each of the drawings 12 to 16, and the drawings can be easily associated with each other.

(2) When additional data is added to the building drawing 17 in order to correct the two-dimensional building drawing 17,
Since the additional data can be stored in a different layer, even if the 3D drawing is corrected and the drawing data is updated (overwritten) after adding the additional data to the drawing data, the additional data remains because the additional data remains. Can be avoided.

(3) Even if one of the plurality of drawings 12 to 16 is modified, the modification data is reflected in the other drawings by the modification reflection processing, so that it is not necessary to individually modify the drawings. Thus, the efficiency of drawing creation can be improved.

(4) Since the building drawing 17 (only the elevations 13 to 16 in this example) is converted to two-dimensional data by setting the z-axis component of the three-axis components to "0", all intersections between lines can be selected. In addition, the correction work is easy, and the data amount can be reduced.

(5) A plan view drawn when a three-dimensional drawing is drawn is used as a reference drawing, and the three-dimensional plan view is a plan view 1.
Since it is used as 2, the correction of the plan view 12 does not take much trouble, and processing such as coordinate conversion may be performed only when the elevation views 13 to 16 are created, so that the program can be simplified.

(6) Since hidden line processing is automatically executed,
It is possible to reduce the work of correcting drawings by an operator. Note that the embodiment is not limited to the above, and for example, may be changed as follows.

The coordinate conversion data used in S102 is not limited to having the coordinate value of the z-axis. That is, the coordinate data of the z-axis of the converted drawing data may be set to coordinate conversion data that is set to “0” in advance. In this way, a program required for the two-dimensional processing can be omitted.

The coordinate conversion data is not limited to that of the above embodiment. That is, when the reference drawing changes, data corresponding to the reference drawing is used as the coordinate conversion data.

The drawing arrangement processing is not limited to the processing of moving each drawing data in the x-axis direction so as not to overlap on the same coordinate axis, and, for example, storing each drawing data on a different layer. At the time of screen display, each layer may be selected and displayed. According to this method, the five types of drawings constituting the building drawing 17 are
One file can be stored, which is convenient for various settings and printing, and it is easy to associate drawings (correction reflection processing and the like).

The z-axis component is set to “0” in order to make the elevation views 13 to 16 two-dimensional. However, the elevation views 13 to 16 are not limited to being made two-dimensional, and may be kept three-dimensional. Then, a scaffolding drawing may be created using the three-dimensional data of the plan view 12 and the elevation views 13 to 16.

The drawing to be created based on the three-dimensional drawing is not limited to one plan view and four elevation views as in the building drawing 17. That is, any combination of a plurality of arbitrary drawings among the six views of the display object may be used. For example, all of the six views may be arranged on the same coordinate axis. Further, another combination such as one plan view and two elevation views may be used.

In this example, the present invention is used for the building drawing 17 for the scaffolding drawing on which the temporary materials are to be arranged, but it can be used for other mechanical design drawings. The technical ideas other than the claims that can be grasped from the embodiment and other examples will be described below together with their effects.

(1) The drawing data according to any one of claims 1 to 3, wherein, in the drawing data displayed on the display means, among drawing data overlapping in an axial component direction orthogonal to the same plane, the drawing data is located on a depth side on a screen. The hidden line processing (S) for erasing the drawing data located and hidden by the drawing data on the near side
106). In this case, it is possible to save the operator the trouble of the correction work.

(2) In claim 1, additional data added by input means to the plurality of drawings displayed on the screen of the display means by the display processing procedure is stored in a layer different from the drawing data. Additional data storage procedure. In this case, even if a drawing is created by adding additional data to a plurality of types of drawings, since the additional data is stored in a different layer, even if the plurality of types of drawings are updated again after adding the additional data, The additional data can be used as is.

(3) In Claims 1 to 3, the reference drawing is a plan view, and the drawing data of the plan view includes the three-dimensional drawing.
Use dimensional data. In this case, even if the reference drawing is a plan view and the three-dimensional data is used as the plan view as it is, the plan view has an advantage that it is easy for the operator to correct the drawing. This is because a three-dimensional drawing is generally created by adding data in the height direction to a plan view. Further, if the three-dimensional drawing is used as a plan view, the coordinate conversion process is reduced by one, and the program is simplified.
