DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drawing printing apparatus for printing drawings and a program recording medium on which a program used for realizing the drawing is stored. The present invention relates to an apparatus and a program recording medium in which a program used to realize the apparatus is stored.

With the spread of CAD systems, CAD drawings created by the CAD systems have been widely used. In order to enhance the practicality of this CAD drawing, it is necessary to make it possible to print an easily usable CAD drawing.
It is necessary to build a printing device for AD drawings.

[0003]

2. Description of the Related Art In a CAD system, by interacting with a designer, a drawing size is set in advance such as A3, and a C
A configuration for creating an AD drawing is employed.

When a CAD drawing created by a designer is printed, a printer capable of printing a printing sheet of a drawing size set by the designer is prepared and the printer is used. The configuration is such that the CAD drawing created by the designer is printed on printing paper of the drawing size set by the designer.

[0005] By the way, CAD drawings, especially architectural CAD
In the drawing, the scale value of the drawing is very important. This is because the actual size value is calculated by measuring the length between two points on the CAD drawing with a ruler and multiplying the length by the reciprocal of the scale value.

[0006] In order to facilitate the use of CAD drawings, designers will use scale values without fractions such as "1/100" or "1/150" as scale values of the drawings. The method of setting is adopted.

When such a scale value having no fraction is set, it is easy to calculate the actual size value by measuring the length between two points on the CAD drawing with a ruler and multiplying the length by the reciprocal of the scale value. And the mistakes go away.

[0008] However, there is a case where a printer capable of executing printing of a printing paper of a drawing size set by a designer cannot be prepared. In such a case, conventionally, a configuration is adopted in which the scale value of the CAD drawing is corrected using the ratio between the drawing size set by the designer and the paper size of the printing paper that can be executed by the printer. According to the reduced scale value, the CAD drawing is reduced and printed.

For example, if the drawing size set by the designer is A
In the case of A3, if the paper size of the printing paper that can be executed by the printer is A4, it is necessary to reduce the size of the printing paper to about 71% of that when printing on the printing paper of A3. For example, a scale value of "1/100"
The CAD drawing is reduced and printed according to the corrected scale value by adopting a configuration that corrects to "1 / 140.8-(where 140.8-is derived from 100 * [1 / 0.71])". I was going to go.

[0010]

However, according to such a conventional technique, when a printer capable of executing printing on a printing paper of a drawing size set by a designer cannot be prepared, a CAD drawing of a printed CAD drawing is not provided. If the scale value is "1"
/140.8- ", which is inconvenient, making its use extremely inconvenient.

That is, when calculating the actual size value by measuring the length between two points on a CAD drawing with a ruler and multiplying the length by the reciprocal of the scale value, a half-width numerical value such as "140.8-" is obtained. Has to be multiplied, which is very inconvenient to use.

Such a problem also occurs when a drawing expressed on a computer other than the CAD drawing is to be printed. The present invention has been made in view of the above circumstances, and provides a new drawing printing apparatus capable of printing an easy-to-use drawing, and a new program recording medium for storing a program used for realizing the drawing printing apparatus.

The drawing management table 50 is provided in association with the drawings 1 and 2 shown in FIG.
As shown in, the name of the CAD drawing to be managed, the comment for the drawing, and the scale value of the drawing
A numerical value such as “100” indicating that the basic scale value is “1/100” and the number of layers constituting the drawing (indicating the number of figures forming the drawing) are managed.

The layer management table 51 is provided in association with the layers 1 to 4 shown in FIG. 4, and as shown in FIG. 6, a name of a layer to be managed, a comment for the layer, , The scale value of the layer is “1”

As described above, a layer manages a figure as a part of a CAD drawing. In the layer management table 51, the origin coordinates of the figure managed by the layer are managed, and the figure is stored in the CAD drawing. The layer scale value of the figure is managed in response to the fact that it can be created at a scale value different from the basic scale value.

In order to cope with a case where the layer scale value is different from the basic scale value, a function of a graphic enlargement / reduction process for adjusting the layer scale value to the basic scale value is provided. In the following description, it is assumed that the layer scale value and the basic scale value are the same, since they are not directly related to the present invention.

As shown in FIG. 8, the print management table 60 manages the print mode, the X and Y coordinates of the center of the paper frame, the scale value for printing, and the upper left and lower right coordinates of the print range. Become. These management values are stored by the processing of the print mode setting program 42 described below.

FIGS. 9 to 12 show an embodiment of a processing flow executed by the print mode setting program 42. FIG.
Next, the present invention will be described in detail according to these processing flows.

When a user issues a print range setting request while displaying a CAD drawing to be printed using the CAD drawing display screen, the print form setting program 42 executes the processing flow of FIG. As shown in FIG. 13, first, in step 1, a print range setting screen as shown in FIG. 13 is displayed on the display using a window (dialog) display format. Here, in this setting screen,
It has a “Breview” button for instructing display of the state when actually printed on the display.

On the print range setting screen shown in FIG. 13, as the print range setting method, there are a print mode of “printing inside the paper frame” and a print mode of “moving and printing the paper frame”. A print mode for printing the entire figure, a print mode for printing the selected range, and a print mode for printing the current display range are provided.

In the print mode of "printing inside the paper frame", the displayed CAD drawing is printed on the printing paper of the assumed printing paper size of the CAD drawing without changing the basic scale value of the CAD drawing. Instruct. The print mode of “moving the paper frame and printing” is to print a part of the displayed CAD drawing on the printing paper of the printing paper size prepared by the printer 4 without changing the basic scale value of the CAD drawing. Instruct. The processing executed in the print mode of “moving the paper frame and printing” will be described later in detail.

In the print mode of “printing the entire figure”, the whole of the displayed CAD drawing is changed to a printing paper of a printing paper size prepared by the printer 4 while changing the basic scale value of the CAD drawing. Print paper of the same size as the print paper). C
Since the AD drawing allows a drawing to be created so as to protrude from the range of the printing paper of the set printing paper size, the printing mode of “printing the entire figure” does not allow the entire printing of such a CAD drawing. Instruct printing.

The print mode of “print selected range” indicates that the CAD drawing of the selected range is to be printed on printing paper of a printing paper size prepared by the printer 4 while changing the basic scale value of the CAD drawing. I do. When the print mode of “print selected range” is set, the print range is set on the displayed CAD drawing by interacting with the user. The print mode of “print the current display range” instructs to print the currently displayed CAD drawing on a printing paper of a printing paper size prepared by the printer 4 while changing the basic scale value of the CAD drawing. .

As described above, when the screen for setting the print range is displayed on the display in step 1, the process proceeds to step 2 (the processing flow in FIG. 9), and is displayed by interacting with the user. When the print mode of the CAD drawing is set and the print mode of “print selected range” is set, unlike the other print modes, the print mode is not automatically determined by the print mode. The print range of the displayed CAD drawing is set by interacting with.

Subsequently, in step 3, the set print mode is stored in the print management table 60, and then in step 4, the print range specified by the set print mode (when the print mode is “print selected range”, The actual coordinates in the CAD drawing corresponding to (the set print range) are obtained, stored in the print management table 60, and the process ends.

According to the processing flow of FIG. 9, when the print mode of “print the whole figure” is set, for example, the print form setting program 42 sets the upper left coordinates for specifying the print range of the entire CAD drawing. (-25000,15000)
When the lower right coordinate is (15000, -20000), as shown in the upper part of FIG. 14, the print mode of "print the whole figure" and the upper left coordinate (-25000) of the print range are stored in the print management table 60. , 15000) and the lower right coordinate of the print range (15000, -2000
0) is stored.

The paper frame center X-coordinate / paper frame center Y-coordinate of the print management table 60 is stored at the time of executing a print mode of “moving the paper frame and printing” to be described later.

When the user sets the print mode (print range) of the displayed CAD drawing in accordance with the print range setting screen shown in FIG. 13, the displayed CAD drawing is in any form by this setting. In order to know whether or not printing is to be performed, the user operates a “Breview” button provided on this setting screen.

When the user operates the “Breview” button, the print mode setting program
As shown in the processing flow of Step 2, first, Step 1
Thus, a preview screen for displaying a print form to be displayed in place of the display screen of the CAD drawing is created.

Subsequently, in step 2, by accessing the driver of the printer 4, the print paper size of the printer 4 is obtained. For example, A4 of "297mm x 210mm"
The print paper size is obtained.

Subsequently, in step 3, the print range set in the processing flow of FIG. 9 and the basic scale value of the CAD drawing to be printed displayed on the CAD drawing display screen (managed in the drawing management table 50). ) To obtain a regular print size when the CAD drawing to be printed is printed on a print sheet of a print paper size set in the CAD drawing, and the obtained regular print size and step 2
Calculate the ratio in the vertical direction / horizontal direction with respect to the print paper size acquired in the step.

For example, the print range set in the processing flow of FIG. 9 is “40000 mm × 35000 mm” defined by upper left coordinates (−25000, 15000) and lower right coordinates (15000, −20000) of the print range.
If the basic scale value of the CAD drawing to be printed is "1/100", "400 mm x 350 mm" is obtained as the regular print size. Then, the obtained regular print size and, for example, “29
7mm x 210mm "in the vertical direction" 400/297 = 1.346
8 ”and the horizontal ratio“ 350 ÷ 210 = 1.66 ”
67 ”.

Subsequently, in step 4, a multiplication value of the larger ratio of the ratios in the vertical / horizontal direction obtained in step 3 and the reciprocal of the basic scale value of the CAD drawing to be printed is obtained. The reciprocal of the scale value for printing when printing the CAD drawing to be printed on the print paper of the print paper size prepared by the printer 4 is determined, and the print scale value determined in this way is stored in the print management table 60. Store.

For example, when the ratio in the vertical direction obtained in step 3 is "1.3468", the ratio in the horizontal direction is "1.6667", and the basic scale value of the CAD drawing to be printed is "1/100", it is large. And the basic scale value “1/667”
By calculating the multiplication value “166.67” of “100” which is the reciprocal of “100”, the reciprocal of the scale value for printing when the CAD drawing to be printed is printed on the printing paper of the printing paper size prepared by the printer 4 “ 166.67 ", and as shown in the upper part of FIG. 14, the print scale value" 1/16 "
“166.67”, which represents “6.67”, is stored in the print management table 60.

Subsequently, in step 5, a drawing management table 50a for printing is created. The drawing management table 50a for printing is executed by specifying a drawing management table 50 stored in the CAD drawing file 3a that manages the CAD drawing to be printed and copying the specified drawing.

Subsequently, in step 6, the number of layers of the CAD drawing to be printed is obtained by referring to the created drawing management table 50a for printing. Then, Step 7
Then, one unprocessed layer is selected from the layers under the management of the created drawing management table 50a, and in the following step 8, it is determined whether all layers have been selected. When it is determined that has not been selected, that is, when it is determined in step 7 that an unprocessed layer has been selected, the process proceeds to step 9 to refer to the layer management table 51 indicated by the selected layer. ,
Get the layer scale value of the selected layer.

Subsequently, in step 10, the layer management table 51 a for printing is created by copying the layer management table 51 indicated by the layer selected in step 7, and the reciprocal of the layer scale obtained in step 9 is calculated. The reciprocal of the print layer scale value is determined by obtaining a multiplication value with the larger ratio specified in step 4, and the print layer scale value determined in this way is copied to the print layer. By storing in the management table 51a,
The printing layer management table 51a is completed.

For example, when the layer reduction value obtained in step 9 is “1/100” and the larger ratio specified in step 4 is “1.6667”, the layer management table 51 shown in the upper part of FIG. 15 is copied. When creating the print layer management table 51a, the multiplication value "16"
By calculating 6.67, the reciprocal of the layer scale value for printing "16
15. Then, as shown in the middle part of FIG. 15, “166.67” representing the printing layer scale value “1 / 166.67” determined as described above is stored in the printing layer management table 51a. By storing, the layer management table 51a for printing is completed.

As described above, the layer scale value stored in the layer management table 51 can be changed for each layer. From this, the print layer scale value stored in the print layer management table 51a also changes for each layer.

Subsequently, in step 11 (the processing flow of FIG. 11), the figure managed by the figure management table 52 indicated by the layer selected in step 7 is reduced according to the layer scale value for printing obtained in step 10. By copying, the graphic management table 52a for printing of the layer selected in step 7 is created, and the process returns to step 7.

As described above, by repeating the processing of steps 7 to 11, in step 8,
When it is determined that all the layers have been selected, the process proceeds to step 12, where the reduced-copy figure is combined (combined according to the coordinate information stored in the figure management table 52a for printing) and displayed on the preview screen. Thus, on the preview screen, a print state when the CAD drawing to be printed is printed while being reduced according to the print scale value obtained in step 4 is displayed, and the print scale value is displayed. A frame indicating the size of the printing paper of the printer acquired in step 2 is displayed.

The print scale value stored in the print management table 60 and the print layer scale value are allowed to be different, and the print layer scale value of each layer is also different. Is allowed, and as described above, a function is provided for adjusting the print layer scale value to this print scale value. However, for convenience of explanation,
Here, it is assumed that all layer scale values have the same value as the print scale value.

The CAD drawing displayed at this time is shown in FIG.
As shown in (1), it is indicated that the print will be performed in a form that fits on the printing paper prepared by the printer 4, but the scale value of the CAD drawing to be printed at that time (this scale value is also printed) Is usually incomplete, such as "1 / 166.67". Here, the broken-line frame shown in FIG. 16 indicates the display of the frame of the size of the printing paper.

Therefore, if the CAD drawing printing program 41 prints the CAD drawing in this state, the user
When calculating the actual size value by measuring the length between two points on the CAD drawing with a ruler and multiplying it by the reciprocal of the scale value,
It is necessary to multiply a halfway numerical value such as "166.67", which makes the use of CAD drawings very inconvenient.

Therefore, the print mode setting program 42
Subsequently, in step 13, it is determined whether or not a request for ending the display of the printing mode has been issued. It is determined whether or not a print scale value change instruction has been issued, and if it is determined that this change instruction has not been issued, step 1 is executed.
By returning to step 2, processing is performed so as to wait for a print scale value change instruction from the user.

If it is determined in step 14 that the user has issued an instruction to change the print scale value to be displayed on the display, the process advances to step 15 to obtain the print scale value of the change input by the user. Then, in the subsequent step 16, the obtained print scale value is stored in the print management table 60.

For example, when the user inputs a new print scale value of “1/200” instead of “1 / 166.67”, as shown in the lower part of FIG. 14, the input print scale value is displayed. "200" which will represent the value "1/200"
Is stored in the print management table 60.

Subsequently, in step 17 (the processing flow in FIG. 12), the number of layers of the CAD drawing to be printed is obtained by referring to the drawing management table 50a for printing created in step 5.

Subsequently, at step 18, one unprocessed layer is selected from the layers under the management of the drawing management table 50a for printing created at step 5, and at step 19, all the layers are selected. When it is determined whether or not all layers have not been selected, that is, when it is determined in step 18 that an unprocessed layer has been selected, the process proceeds to step 20 where the selected layer is selected. By referring to the print layer management table 51a pointed to by, the print layer scale value indicated by the selected layer is acquired.

Subsequently, in step 21, if the reciprocal of the new print scale value acquired in step 15 is S1 and the reciprocal of the print scale value before the change is S0, the following is obtained. The reciprocal of the new layer scale value for printing is calculated in accordance with the calculation formula of S1 ÷ S0, and the printing layer scale value determined in this manner is determined by the corresponding printing layer. It is stored in the management table 51a.

For example, the reciprocal of the new print scale value obtained in step 15 is “200”, the reciprocal of the print scale value before change is “166.67”, and the print layer scale value obtained in step 20. When the reciprocal of is “166.67”, the reciprocal of the new layer scale value for printing “200” is determined, and
As shown in the lower part of FIG. 15, “200”, which represents the printing layer scale value “1/200” determined in this manner.
Is stored in the layer management table 51a for printing.

Subsequently, in step 22, according to the print layer scale value obtained in step 21, the print graphic management table 52a indicated by the layer selected in step 18 is used.
Then, the process returns to step 18 after reducing the figure to be managed.

By repeating the processing of steps 18 to 22 in this way, step 19
When it is determined that all layers have been selected, step 1
2 (the processing flow of FIG. 11), the graphic reduced in step 22 is synthesized (combined in accordance with the coordinate information stored in the graphic management table 52a for printing), and displayed on the preview screen. In response to this, the print state when the CAD drawing to be printed is printed while being reduced according to the print scale value obtained in step 15 is displayed, and the print scale value is displayed. A frame indicating the size of the printing paper of the printer is displayed.

As shown in FIG. 17, the CAD drawing to be printed displayed at this time is displayed in a form smaller than that shown in FIG. 16 in accordance with the print scale value specified by the user. The scale value for printing of the CAD drawing that is sometimes printed (this scale value is also printed) has no fraction, such as "1/200" according to the instruction from the user.

When the user obtains a CAD drawing to be printed by the CAD drawing printing program 41 in accordance with the printing scale value set in this manner, the user measures the length between two points on the CAD drawing with a ruler. When calculating the actual size value by multiplying it by the reciprocal of the scale value, for example, "200
The actual size value can be calculated by multiplying a numerical value having no fraction, such as "", so that the CAD drawing becomes very easy to use.

Next, the processing executed by the print mode setting program 42 when the print mode of “moving the paper frame and printing” is selected on the print range setting screen shown in FIG. 13 will be described.

The print form setting program 42 uses a CAD drawing display screen as shown in FIG. 18 to print one CAD drawing (the CAD drawing of FIG. 18 is composed of four drawings). When a print range setting request is issued from the user while displaying a single CAD drawing), the print range setting screen as shown in FIG. To display on the display.

As described above, the 1 to be printed is
A sheet of a CAD drawing is created by setting a sheet size of a printing sheet such as A1, for example. In response to the display of the print range setting screen, when the user selects the print mode of “moving the paper frame and printing”, first, as shown in the processing flow of FIG.
The print range setting screen is erased, and in the subsequent step 2, it is determined whether or not the mouse of the terminal 2 has been operated. When it is determined that the mouse has been operated, the process proceeds to step 3, and the operation is performed. It is determined whether or not the operation is a mouse movement operation.

If it is determined in this determination process that the operation is a mouse movement operation, the process proceeds to step 4, where the size of the printing paper of the printer 4 is set at the position indicated by the mouse as indicated by the broken-line frame in FIG. The paper frame shown is displayed.

At this time, the size of the paper frame to be displayed is CA
The size is determined based on the relationship with the size of the print paper frame set in the D drawing when the paper frame is displayed. Here, it is assumed that the print paper size of the printer 4 has already been acquired by accessing the driver of the printer 4 according to the processing flow of FIG. By accessing the driver 4, the print paper size of the printer 4 is obtained.

On the other hand, when it is determined in step 3 that the operation is not a mouse movement operation, the flow advances to step 5 to determine whether or not the left button of the mouse has been operated. Is returned to step 2 without performing any processing. On the other hand, when it is determined that the left button of the mouse has been operated, the process proceeds to step 6, where the center coordinates of the displayed paper frame are obtained, and
It is stored in the entry of the paper frame center coordinates (X coordinate / Y coordinate) in the print management table 60, and in the following step 7,
The print range setting screen is displayed again, and the process ends.

Upon receiving the coordinates of the center of the paper frame in the print management table 60, the CAD drawing print program 41
Is the center of the paper frame center,
The CAD drawing is printed on printing paper of a printing paper size prepared by the printer 4 by printing the D drawing according to the basic scale assumed by the D drawing.

The print scale value of the CAD drawing printed in this way does not have a fraction such as “1/100” because it matches the basic scale value assumed by the designer of the CAD drawing. become.

When the user obtains the CAD drawing to be printed, the user measures the length between two points on the CAD drawing with a ruler and calculates the actual size value by multiplying the length by the reciprocal of the scale value. Then, the actual size value can be calculated by multiplying a numerical value having no fraction, for example, "100", so that the CAD drawing becomes very easy to use.

That is, in the embodiment according to the processing flow shown in FIGS. 10 to 12, when the CAD drawing must be reduced and printed due to the small size of the printing paper prepared by the printer 4, the user must By adopting a configuration in which a CAD drawing having a print scale value having no fraction is set by setting a print scale value having no fraction, it is possible to realize easy-to-use CAD drawing printing. In the embodiment according to the processing flow of FIG. 19, the size of the printing paper prepared by the printer 4 is small,
When a D drawing must be printed in a reduced size, the user is required to specify a CAD drawing portion to be printed at the basic scale value assumed in the CAD drawing, and only the portion is printed according to the basic scale value. By adopting it, it is possible to realize easy-to-use CAD drawing printing.

The present invention has been described with reference to the illustrated embodiments.
The present invention is not limited to this. For example, in the embodiments, the present invention has been described by using a CAD drawing as a specific example. However, the present invention can be applied as it is even when a drawing expressed on a computer other than the CAD drawing is to be printed.

Further, the present invention can be applied to printing of various data such as text data other than drawings, and in this case, a unique scale value defined by the size of the printing paper is used. This has the significant effect of preventing printing on a printed image and printing at a scale value desired by the user.
