[0008]

According to the first aspect of the present invention, the recognizing means generates the data showing the members representing the skeleton and the fitting and the data showing the positions of these members from the plan view data including the skeleton and the fitting created in advance by CAD or the like. By recognizing,
Recognize the members that show the frame and fittings. This plan view data is data in which members indicating a skeleton and a fitting are represented by two-dimensional coordinate data, and thus code data does not need to be input as in the conventional case, so that the data can be easily created.

The recognition means preferably recognizes the door, the window, the wall and the pillar in this order in order to correctly recognize the wall and the pillar which are the members showing the skeleton and the door and the window which are the members showing the fitting. Since the members indicating the frame and the fittings are drawn with predetermined symbols, the door can be recognized by determining whether or not there are arcs and line segments continuous with the arcs. Further, the window is recognized by determining whether or not three parallel lines are present, the wall is recognized by determining whether or not two parallel lines are present, and a line segment representing a line core is identified.

[0017]

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1 shows a schematic view of the present embodiment. A personal computer 10 for creating architectural drawings is a CPU,
It is configured to include a ROM and a RAM. The personal computer 10 includes a tablet (digitizer) 1
6 is connected. Further, the electronic pen 18 is provided, and by moving the tip of the electronic pen 18 in contact with the surface of the tablet 16, the movement locus is converted into point sequence data and input into the personal computer 10.

The tablet 16 is preferably a tablet combined with a liquid crystal display device, and by using this tablet to display a menu screen or the like on the liquid crystal display device, menu selection with the electronic pen 18 or electronic pen display is possible. Data entry becomes easy. Further, a display for display (CRT) 12 can be optionally connected.

ROM of this personal computer 10
The program of the architectural drawing creation routine described below is stored in advance in the. This routine will be described below.

First, the operator turns on the power of the architectural drawing creating apparatus and selects a plan view data created in advance by CAD by selecting a menu displayed on the tablet 16 or the like, or a member showing a skeleton and a fitting. Enter the height data. These plan view data and height data are R
Recorded in AM.

An example of this plan view data is shown in FIG. In this plan view, a door is drawn by an arc and a line segment continuous to this arc, a window is drawn by three parallel lines, and
A wall is drawn by parallel lines of the book, a pillar is drawn by a quadrangle in the vicinity of an intersection of line segments that represent a core, and a large number of parallel lines draw a staircase. At this time, the plan view data may be only two-dimensional graphic data representing each line segment and arc of the plan view. Also, as height data, the height of the door,
Window height and waist height, number of floors, floor height, ceiling height, slab thickness,
Enter the beam width, beam formation, etc. As the height data, standard data may be displayed in advance, and only the portion different from the actual height data may be corrected by handwriting with the electronic pen. By doing so, data input is further simplified. Further, the operator designates whether the type of drawing to be drawn is a perspective view (perspective), an elevation view or a sectional view.

In step 100 of FIG. 2, the plan view data recorded in the RAM is fetched, and in the next step 101, it is judged whether or not the mode for designating the outline is selected, and the outline designating mode is not selected. In this case, in the next step 102, the height data recorded in the RAM is fetched. In the next step 104, the skeleton data representing the member indicating the skeleton and the fitting data representing the member indicating the fitting are extracted based on an extraction routine whose details will be described later to recognize the skeleton and the member indicating the fitting. In step 106, the data representing the member recognized as described above is integrated for each member, and a label for identifying the member is attached to the integrated data. From this label, a set of data and a member can be associated with each other.

In step 108, it is judged whether the drawing designated by the operator is a perspective view, an elevation view or a sectional view. Then, in step 110, the label and the data corresponding to the label are determined to determine the position and area of each member on the plan view, and the height data for each member is added to the plan view data for each member. By doing so, three-dimensional coordinate data is generated, a designated drawing is automatically created by using a technique known in CAD, and is displayed on the display device 16 or 12. In FIG.
The example of the perspective created based on the plan view of 0 and the input height data is shown.

In the next step 112, step 110
Create a detailed view of the drawing created in,
As shown in (3), an elevation view including a potted window, a continuous window, and a curtain wall for examining the appearance of a building is created, and an estimate or the like is created. In addition, the direction and angle of the perspective can be changed if necessary. Of the post-processes, the examination of the appearance of the building will be described in detail later.

Next, referring to FIG. 3, a recognition routine for recognizing the members showing the frame and the fitting in step 100 will be described. First, in step 200, the plan view data is fetched from the RAM, and in step 202, it is judged whether or not an arc exists. If no arc exists, the process proceeds to step 210, and if an arc exists, step 20.
In step 4, it is determined whether or not there is a line segment whose one end is continuous with the circular arc determined in step 202.
If the determination is positive, it is determined in step 206 whether the other end of the line segment determined in step 204 coincides with the center of the arc. When the determination in step 206 is affirmative, as shown in FIG. 7, it is determined that there is a door symbol drawn by the arc A and the line segment S, and the arc A and the line segment S are used as the data of the door D. The extracted door data is recorded in a predetermined area of the RAM and deleted from the plan view data. When the determinations at step 204 and step 206 are negative, the process directly proceeds to step 210. The processing from step 202 to step 208 is repeated until all door data is extracted.

In the architectural drawing, since three parallel lines P are drawn as windows as shown in FIG. 8 , it is judged in step 210 whether there are three parallel lines having the same length.
When they exist, these three parallel lines are extracted as window data, recorded in a predetermined area of the RAM, and the extracted window data are deleted from the plan view data. Step two
The process of 10 and step 212 is repeated until all window data are extracted.

Since two parallel lines are drawn as walls in the architectural drawing, in the next step 214, it is judged whether two parallel lines are present or not, and it is judged that two parallel lines are present. In this case, in step 216, these two parallel lines are extracted as wall data, and the extracted data is stored in the RAM.
Is recorded in a predetermined area of and erased from the plan view data.

In this case, as shown in FIG. 7, step 2
Since the door is recognized in 08 and the door data is erased from the plan view data, a set of two parallel lines P1 and P2, 2
A set of parallel lines P3 and P4 of the book is recognized as walls W1 and W2. Since the line segments P6 and P7 form a pair with the line segment P5 to form one wall, the line segment P6, which is separated at a narrow interval,
P7 is recognized as one line segment, and line segments P6, P7, P5
The wall W3 is recognized by the group. The processes of steps 214 and 216 are repeated until all the wall data are extracted.

In the next step 218, it is judged whether or not there is a line segment representing the line core, and when this line segment exists, a square is formed in the vicinity of the intersection of the line segment representing the line core in step 220. Determine if it exists. As shown in FIG. 9, since the pillar exists in the vicinity N of the intersection of the line segments L1 and L2 representing the core, steps 218 and 220
If the determination is affirmative, in step 222, the 4
The polygon G is recognized as a pillar, stored in the RAM, and the extracted data is deleted from the plan view data. Step 21
The processing from 8 to step 222 is repeated until all the columns are extracted.

On the other hand, if it is determined in step 101 that the mode for designating the outline has been selected, step 1
At 03, the outline data is specified and the window is recognized based on the outline data specification and window extraction routine.

Further, the operator preliminarily inputs the height data of the contour and designates whether the type of drawing to be drawn is a perspective view or a perspective view. Here, the height data of the outer contour includes the number of floors, floor height, and the like. At this time, window data may be input together with the height data of the outer contour. The window data input here is window height data such as window height and waist height. Note that these window data may be stored in the RAM with predetermined values as initial values in advance, and the input by the operator may be omitted.

As shown in FIG. 4, in the contour data designation and window extraction routine, height data of the contour is fetched in step 300. When the window data is input together with the height data of the outer contour, the window data is also captured. In the next step 302, the plan view data is displayed on the tablet 16, and it is determined in the next step 304 whether or not the outline data is designated. The designation of the outer contour data is performed, for example, in FIG.
, The window symbol 22 (22A to 22D) drawn with three parallel lines, the wall symbol 24 (24A to 24H) drawn with two parallel lines, and the line representing the line core. From the plan view data including the pillar symbol 26 (26A to 26D) drawn in a quadrangle near the intersection of the minutes,
The line outside the window symbol 22, the line outside the wall symbol 24, and the two lines outside the pillar symbol 26 are connected to the electronic pen 18.
Specify by. Then, the specified contour data is recorded in a predetermined area of the RAM. 13 is the same as FIG.
FIG. 6 is a diagram showing a state in which outline data is specified by the electronic pen 18 from the plan view data shown in FIG. 2. It should be noted that the window symbol and wall symbol of the plan view data only need to have parallel lines, and the parallel lines here mean two or more lines that maintain a predetermined interval. Curves are included in addition to straight lines.

In step 304, the process waits until the contour data is designated. If the contour data is designated, in step 306, the plan view data has two parallel lines parallel to the contour data and having the same length. Determine whether or not. 14
If there are two parallel lines having the same length in step 306, the extracted window data is recorded in step 308, the extracted window data is recorded in a predetermined area of the RAM, and the label is displayed. Is added to erase the window data recorded from the plan view data, and the process proceeds to step 306.
The processes of steps 306 and 308 are repeated until all window data are extracted.

If there are no two parallel lines that are parallel to the contour data and have the same length in step 306, the routine ends.

Next, in step 108 of FIG. 2, it is judged whether the designated drawing is a perspective view or an elevation view, and in step 110, the window data (window position information) thus extracted is input. Generated or pre-stored window data (window height data) is added to the contour data to generate contour three-dimensional coordinate data, and the technique known in CAD is used. Then, the designated drawing is automatically created and displayed on the tablet 16 or the display 12. FIG. 15 shows an example of the perspective created based on the window recognized as the contour data of FIG. 14, the inputted contour height data, and the window data.

When the appearance of the building is to be examined in the step after step 112 in FIG. 2, the window examination mode is selected from the menu screen displayed on the tablet 16. Figure 5
In step 400 of 1., it is determined whether or not the window review mode is selected. If the window examination mode is not selected in this step 400, the routine ends, and if the window examination mode is selected, it is determined which wall window is to be examined, and in step 402, the current window is selected. The window data input screen as shown in FIG. 6 in which the data is displayed is displayed on the tablet 16.

This window data input screen is a display section in which a plurality of sets of figures representing windows each including a rectangular frame 30 corresponding to a space, a rectangular frame 32 corresponding to a window, and a rectangular frame 34 corresponding to a waist window are arranged. It has a certain window 31 and an input unit 33 for inputting window data. The input unit 33 is
Windows 36A and 36B for inputting width (W) and height (H) between columns, windows 37A and 37B for inputting window width (W) and height (H), width of waist window (W) and Window 3 for entering the height (H) respectively
8A, 38B, windows 39A, 39B for inputting adjacent window spacings a, b, window 39C for inputting column spacing and window spacing c, window 39D for inputting window and waist window spacing d, window for inputting waist height h 40, a window 41 for inputting the total number N for each wall, left and right empty spaces L, R
42A, 42B for inputting, respectively, windows 43A, 43B for inputting the passing direction (longitudinal, horizontal) of the curtain wall, and window 44A for inputting the type of window (fixed "FIX", open, pull, rattle) Four
4B, 44C, 44D, windows 46A and 46B for inputting whether or not to replace the windows, a window 47 for selecting an elevation display, a window 48 for selecting close, and a window 49 for selecting execution. Also, the window data input screen has an upper title portion 29A displayed as "elevation", "window examination" and "collective arrangement", and "scale 1/20".
0 ”,“ all ”,“ enlarge ”,“ 1/2 ”, double-headed arrow,
It also has an upper title portion 29B displaying "Drawing", "UNDO", and "ESC". If there is no corresponding current window data, each window is blank.

In step 404 of FIG. 5, it is determined whether window data is input using this input screen, and if it is input, the window data is updated based on the input data and input. If not, the process proceeds to the next step 406 without changing the original data. The window data means the width and height of columns, the width and height of windows, the width and height of waist windows, the intervals between adjacent windows, the intervals between columns and the intervals between windows, the intervals between windows and waist windows, waist height, each It refers to the total number of each wall, the left and right space, the direction of the curtain wall, the type of window, etc.

In step 406, it is determined whether or not the elevation display is performed. If the elevation display is performed, the following step 40 is performed.
An elevation view is created (corrected) based on the window data input in 8 and displayed on the display 12. FIG. 16 shows an example of an elevation view created based on the plan view data of FIG. 12, the specified outline data, the input outline height data, and the input window data. If the elevation display is not performed in step 406, the process proceeds to step 410.

At the next step 410, it is judged whether or not the window examination mode is ended. If the window consideration mode is not to be ended, the routine proceeds to step 402, and if the window consideration mode is to be ended, the routine is ended.

A perspective may be created based on the above-mentioned examination of the appearance of the building, or a bottom plan view may be created. FIG. 17 shows an example of a simple perspective corresponding to the elevation view of FIG. 16, and FIG. 18 shows an example of a bottom plan view corresponding to FIGS. 16 and 17. In the plan view, the wall symbol 50 (50A to 50F) is drawn by one line, and the window symbol 51 (51A and 51B) is
It is drawn by two line segments that extend along each other and a line segment that is orthogonal to these line segments at both ends. When displaying the bottom plan,
It is preferably displayed adjacent to the original floor plan data to facilitate modification of the original floor plan data.

As described above, according to the present embodiment, when the contour data is not designated, the door, the window, the wall and the pillar are recognized in this order.
It is possible to correctly recognize the door and the window, which are members showing the fittings.

Further, when the contour data is designated, the contour can be recognized without error by this designation, and even when the plan view data has a complicated contour including a curve or unevenness, Examples can be applied.

Furthermore, when examining the appearance of a building,
Because the window is displayed by the combination of the rectangular frame corresponding to the window, the rectangular frame corresponding to the window, and the rectangular frame corresponding to the waist window, the specified drawing, that is, the elevation view and the perspective can be created. In addition, it is possible to increase variations when performing the appearance examination and reduce the time and effort required to create the elevation view and the perspective.

The window data input screen shown in FIG. 6 is used not only in the window examination mode but also when the window data is first input. In step 300 of FIG. When importing, the necessary data described above may be imported from the input window data.
