FIG. 1 is a diagram illustrating an apparatus and method for adjusting a scaled object of a CAD object according to the present invention.

Referring to Fig. 1, a plurality of view areas 10_1 to 10_n and one sheet area 20 are shown. The view areas 10_1 to 10_n are spaces in which CAD objects generated according to the CAD input information received from the CAD user are drawn, and each of the view areas 10_1 to 10_n has respective view area scale values 11_1 to 11_n . These view areas 10_1 to 10_n and the view area scale values 11_1 to 11_n are generated by the values inputted by the user.

When the CAD objects according to the CAD input information are generated in the view areas 10_1 to 10_n created by the user, the view area maps 12_1 to 12_n, in which the CAD objects according to the CAD input information are drawn, are displayed in the view areas 10_1 to 10_n, Is generated.

On the other hand, the sheet area 20 is an area for outputting to the paper sheet, and has information on the sheet sheet size value 21 and the paper size 22.

The user can move the view area maps 12_1 to 12_n shown in the view areas 10_1 to 10_n to the sheet area 20. When the view area drawings 12_1 to 12_n are moved to the sheet area 20, As the scale of the CAD object is adjusted, new sheet area drawings 30_1 to 30_n are generated according to the view area scale and the sheet scale. The user moves the reference points 13_1 to 13_n of the view area drawings 12_1 to 12_n into the sheet area 20 so that the view area drawings 12_1 to 12_n are drawn again in the sheet area 20 in accordance with the scale . The points at which the reference points 13_1 to 13_n of the view area drawings 12_1 to 12_n are shifted into the sheet area become the reference points 33_1 to 33_n of the sheet area map 33_1.

FIG. 2 is a block diagram illustrating an apparatus for scaling and adjusting a CAD object according to the present invention, and FIG. 3 is a flowchart illustrating a scaling adjustment method for a CAD object according to the present invention.

The scaling adjustment method of the CAD object according to the present invention is essentially the same as the scaling adjustment device of the CAD object according to the present invention, and will be described below.

Referring to FIG. 2, the CAD object scaling adjustment apparatus 100 includes a view area generation unit 110, a sheet area generation unit 120, a scaling adjustment unit 130, and a database 140.

The view area generating unit 110 generates at least one view area having a predetermined view area scale value (S100). The size of the view area and the view area scale value are determined according to the input information input from the user.

The view area generating unit 110 includes a view area drawing unit 111. The view area drawing unit 111 draws CAD objects in each generated view area to generate a view area map (S200).

On the other hand, the CAD object includes at least one of a shape object and an annotation object, and may further include a composite object.

The shape object is a physical element related to the shape of a CAD object and means a general shape object such as a general line, a polyline, a polygon, a rectangle, a spiral, a circle, a circle, a donut, and an ellipse. This shape object is not affected by the view area scale value, but is influenced by the area factor described later. An annotation object is a descriptive element that describes a CAD object, which means a character or attribute character. These annotation objects are affected by the view area scale value, but are not affected by the area factor. Finally, a composite object is a descriptive element that describes a CAD object, which means the dimension value or hatch pattern of the CAD object. These composite objects are both affected by the view area scale value and the real-time factor.

Therefore, for the shape object of the view area generation unit 110, the drawing is performed without scaling according to the view area scale value. For the annotation object and the composite object, the view area is scaled according to the view area scale value, do.

 The sheet area generation unit 120 generates a sheet area having a predetermined sheet scale value and a paper size (S300). The size of the sheet area, the sheet scale value, and the sheet size are determined according to the input information input from the user.

The user may move the viewpoint area drawing into the sheet area by moving the reference point of the view area drawing into the sheet area (S400).

The scaling adjustment unit 130 calculates an area factor represented by a view area scale value versus a sheet scale value and includes an area factor calculation unit 131. When the view area drawing enters the sheet area, And a sheet area drawing unit 132 for generating a sheet area drawing by re-drawing the view area drawing within the sheet area (S500) by scaling the annotation object based on the view area scale value (S500). That is, when the view area drawing is moved into the sheet area, the shape object is scaled and drawn according to the area factor, and the annotation object is drawn according to the view area scale value. On the other hand, the scaling adjustment unit 13 scales and draws the composite object according to the area factor.

The database 140 includes a CAD object database 141 that stores each CAD object in a database, and includes a view area database 142 for storing the generated view area, and a sheet area database 142 for storing the generated sheet area. (143).

On the other hand, the scaling of the shape object and the annotation object in the scale region will be described in more detail.

The shape object is not influenced by the view area scale value when it is drawn in the view area, so there is no change in size or position, and when it is drawn in the sheet area, its size or position changes according to the area factor value. For example, if a line with a length of 100 is placed in a sheet area with an area factor of 0.5, the length of the object will be 50 (original object length * 0.5 = 100 * 0.5 =).

On the other hand, as described above, the area factor is a factor value applied when a view area having a different view area scale value is placed on one sheet, and the area factor is a view area scale / sheet scale. For example, if the sheet scale is 1/100 and the view area scale value is 1/200, the area factor is 0.5. As a result, when the shape object is moved from the view area to the sheet area, the magnitude change and the position change which are multiplied by the area factor based on the reference point occur at the same time.

On the other hand, the annotation object varies in size or position due to the influence of the view area scale value in the view area, but is not affected by the area factor in the sheet area.

4 is a diagram illustrating a case where a shape object and an annotation object are drawn in a view area having different view area scale values, respectively.

Referring to FIG. 4, although the view area scale values are different from each other, the shape objects are drawn in the same size, and the annotation object is reduced according to the view area scale value.

The method of the present invention can also be embodied as computer readable code on a computer readable recording medium. A computer-readable recording medium includes all kinds of recording apparatuses in which data that can be read by a computer system is stored. Examples of the computer-readable recording medium include a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, an optical data storage device, and the like, and may be implemented in the form of a carrier wave (for example, transmission via the Internet) . The computer-readable recording medium may also be distributed over a networked computer system so that computer readable code can be stored and executed in a distributed manner.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the invention. Accordingly, the scope of protection of the present invention should be construed in accordance with the following claims, and all technical ideas within the scope of equivalents and equivalents thereof should be construed as being covered by the scope of the present invention.
