Abstract

PURPOSE:To easily correct a handwritten drawing at a high speed and to make a data base of the correction result to reduce the space for drawing storage. CONSTITUTION:A handwritten drawing input processing 1 reads in the handwritten drawing from an image scanner 2 to display it in an image layer. A CAD drawing editing processing 3 uses CAD to plot, change, and edit a drawing to display the CAD drawing in an editing layer. A handwritten drawing partial deletion processing 4 deletes unnecessary parts from the handwritten drawing in the image layer. A drawing synthesizing and output processing 5 synthesizes the handwritten drawing in the image layer after deletion and the CAD drawing in the editing layer and outputs the result.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a CAD system, and more particularly to a CAD system in which handwritten drawings and CAD drawings coexist.

[0002]

2. Description of the Related Art A conventional CAD system has a function of simply displaying an entire handwritten drawing on a CAD display screen for raster data in which a handwritten drawing or the like is input, but a function of correcting the handwritten drawing. Did not have.

[0003]

SUMMARY OF THE INVENTION Conventional CAD described above
Since the system does not have a correction function for raster data, it has a drawback that it is difficult to make corrections to a handwritten drawing once created.

The object of the present invention is to eliminate the need to recreate a new drawing even when the handwriting drawing needs to be modified.
Provided is a CAD system in which correction of handwritten drawings can be performed easily and at a high speed, and by correcting the handwritten drawings, the drawings of the correction results can be stored in a database to save space in storing the drawings. To do.

[0005]

A CAD system according to a first aspect of the present invention comprises (A) a handwriting drawing input process for reading a handwriting drawing by an image scanner and displaying the read image data on an image layer; B) From the CAD drawing editing process of drawing and changing and editing the drawing by CAD and displaying the created CAD data on the editing layer, and (C) the image data displayed on the image layer by the handwriting drawing input process, By the handwritten drawing portion deleting process for deleting the unnecessary portion due to the CAD data created by the CAD drawing editing process, and (D) the CAD data created by the CAD drawing editing process and the handwritten drawing part deleting process And a drawing combination output process for combining the image data after deletion and outputting the combined data.

The CAD system of the second invention is
(A) Read the handwritten drawing with the image scanner and display the read image data on the image layer. (B) C
Drawing and changing and editing drawings by AD,
The created CAD data is displayed on the editing layer, and (C) the CA data is displayed based on the image data displayed on the image layer.
Delete the part that is no longer needed because D data was created,
(D) Combining the CAD data and the image data after deletion and outputting composite data.

[0007]

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a CAD system of the present invention. 2 is a diagram showing an example of an image layer and an editing layer in the display of the CAD system of this embodiment.

In the CAD system of this embodiment, as shown in FIG. 1, the handwriting drawing input processing 1 is performed by the image scanner 2
The handwritten drawing is read by and the read image data is displayed on the image layer 21 shown in FIG.

Further, the CAD drawing editing process 3 draws, changes and edits the drawing by using the CAD, and displays the created CAD data on the editing layer 22.

Therefore, the handwriting drawing portion deletion processing 4 deletes the portion of the image data displayed on the image layer by the handwriting drawing input processing 1 that is no longer needed because the CAD data was created by the CAD drawing editing processing 3. ing.

Then, the drawing synthesis output processing 5 synthesizes the CAD data created by the CAD drawing editing processing 3 and the image data deleted by the handwriting drawing portion deletion processing 4, and outputs the synthesized data.

FIG. 3 is a diagram showing an example of correcting a part of a handwritten drawing according to this embodiment. As shown in FIG. 3, the handwriting drawing input process 1 first reads the handwriting drawing 31 to be corrected and displays the image layer drawing 32.

On the other hand, the CAD drawing editing process 3 uses CAD on the editing layer drawing 33 to draw the portion marked with a circle to be corrected to create and display the editing layer drawing 34.

Further, the handwriting drawing portion deletion processing 4 generates an image layer drawing 35 in which the portion marked with Δ is deleted from the image layer drawing 32.

Next, the drawing synthesis output processing 5 generates and outputs a synthesis drawing 36 in which the image layer drawing 35 and the editing layer drawing 34 are combined.

[0017]

As described above, the CAD of the present invention
The system is able to
There is no need to recreate a new drawing, and handwritten drawings can be easily and quickly corrected, and by making corrections to handwritten drawings, the drawings of the correction results can be stored in a database to save drawing storage. It has an effect that space can be achieved.
