(First embodiment)
Hereinafter, a design support apparatus 10 according to a first embodiment of the present invention will be described with reference to FIGS.

  The design support apparatus 10 of this embodiment is a system that supports the design when a rectangular outer wall material is attached to the outer wall of a house, and can be realized by a program that runs on a personal computer.

(1) Explanation of terms First, terms used in this specification will be explained.

  “Assignment” means that an outer wall material, which is one of the rectangular members, is sequentially arranged on the wall surface.

  “Real” represents an outer wall material that can be allocated to the outer wall material to be allocated with the member size as shipped. The member size in the case of an outer wall material is not a member in a shipped state, but represents a member cut into a multiple of a building module within a member size range in a shipped state. For example, in the case where the building module is a 910 mm module and the horizontal size in the shipment state is 3030 mm, the member size used for the allocation is 3030 mm or less and the maximum value is a multiple of 910 mm. 910 mm × 3 = 2730 mm.

  The “cut” refers to a member that performs allocation by cutting the member to be allocated from the original member size. The permissible range for cutting is up to the length of the member in the state where the outer wall material is shipped vertically and horizontally.

(2) Configuration of Design Support Device 10 The configuration of the design support device 10 will be described with reference to FIG.

  The design support apparatus 10 includes a control unit 12, a display device 14 including a liquid crystal display device connected to the control unit 12, a printer 16, a keyboard 18, a mouse 20, and a scanner 22. The control unit 12 includes a plurality of storage devices, the first storage device is a member data storage device 24 that stores member data, and the second storage device is real data that stores real data. The storage means 26, and the third storage device is a cut data storage means 28 for storing cut data.

  Each device of the design support device 10 can be realized by a personal computer.

(3) Operational state of design support device 10 Next, using the design support device 10 having the above-described configuration, processing contents in which the designer automatically assigns the outer wall material to the outer wall of the house will be described in order based on FIG. . Note that a program for realizing this processing content is stored in the control unit 12.

  In step 1, the design drawing showing the outer wall of the house is input by the scanner 22. In this case, enter at least four east, west, north and south design drawings of the house, and if necessary, enter a plan drawing of the plane and a design drawing of the wall that cannot be seen from the four directions of east, west, south, and north. To do.

  In step 2, a scale is set for each input design drawing. In other words, the design drawing displayed on the screen of the display device 14 is set on a scale of, for example, 1/100 by enlarging or reducing. In this case, if the design drawing input is tilted, the tilt is corrected. And as shown in FIG. 4, 1.0 cm on a screen is set so that it may actually become 1 m.

  In step 3, the member of the outer wall material to be assigned to the outer wall is selected from the outer wall material stored in the member data storage device 24 and set. The member data storage device 24 stores an outer wall material identification number of each outer wall material, and a single vertical dimension and horizontal dimension of the real object. In addition, the shape of the member allocated in the design support apparatus 10 is a rectangle including a square.

  In step 4, the actual size of the wall in one direction in the scaled design drawing is calculated. Here, since the actual size of the wall surface in the south direction is first calculated, the actual size of the wall surface in the south elevation is calculated.

  First, in FIG. 4, the lengths a to g on the respective wall surfaces and the lengths hm of the three windows are obtained. This length is obtained by moving the cursor from the lower left point O of the wall surface (hereinafter referred to as the wall surface origin O) to the point A at the other end with the mouse 20 according to the moving distance. Find the length. This moving distance can be expressed by a scale of 1/100 as described above. The wall surface origin O and the coordinate position of the point A on the screen are also stored. This coordinate position is performed based on the orthogonal absolute coordinate system x-o-y in FIG. This point o is the origin of the absolute coordinate system.

  Second, the area of the openings of the three windows is obtained from hm. This calculation is obtained by integrating h and i obtained above.

  3rdly, the area of the whole wall surface is calculated | required by ag.

  Fourth, the true area of the wall surface is obtained by subtracting the opening area of the three windows from the area of the entire wall surface.

  In step 5, initial allocation of the outer wall material is performed. In addition, suppose that an outer wall material is allocated by horizontal sticking.

  First, since the outer wall material to be assigned in step 3 is set, the outer wall material identification number, the true vertical dimension, and the horizontal dimension of the set outer wall material are transferred to the true data storage device 26.

  Second, the initial allocation is performed for each vertical dimension and lateral dimension of the real data of the outer wall material selected in a grid pattern in the right and upward directions with the wall surface origin O as the center, as shown in FIG. Divide the areas into shapes. In other words, the horizontally long rectangular region in the wall surface in FIG. 5 is a state in which a single outer wall material is pasted and pasted.

  In step 6, the designer confirms the state of the initial assignment on the display device 14, determines whether the assignment state is aesthetically and functionally good, and starts to assign the real thing if there is a problem. A point (hereinafter referred to as a true assignment start point) is moved from the wall surface origin O. For example, in FIG. 6, the real assignment start point is moved to the right, and the real assignment start point is moved to the P point.

  In step 7, the real object and the cut object are allocated in a grid pattern with the real object allocation start point P as the center. This allocation process will be described in detail later. The state in which the assignment process is completed is the state of FIG. 7, and in the south elevation, the state in which each outer wall material is assigned is shown, and the reference numerals shown on the outer wall material are directions (for example, “ South ”), F being true, C being cut, each number represents a real identification number and a cut identification number.

  In step 8, it is determined whether or not to assign the design drawings in other directions. This determination is made in advance by determining the priority order, first performing a south elevation, and then performing an east elevation, a west elevation, and a north elevation in that order.

  When the assignment to all the four elevations is completed, the process proceeds to step 9 to print and finish the design drawings of all the elevations. If there is still a next elevation, the process returns to step 4.

  In this way, the assignment can be automatically performed for each elevation in each direction, and in that case, the real assignment start point can be moved and assigned in the most beautiful state.

(4) Allocation Processing Next, details of the allocation processing in step 7 in the flowchart of FIG. 2 will be described based on the flowchart of FIG.

  In step 11, the real thing is assigned from the real assignment start point P. In the following description, the outer wall material is assigned by lateral pasting.

  In this allocation method, in FIG. 7, a grid-like area is set for each of the vertical and horizontal dimensions of the real object in the upward and lateral directions around the point P, and the real outer wall material is placed in the set area. The portion that can be used in the horizontal pasting as it is is stored as a real allocation area, and the real identification number assigned to each real allocation area is stored. For example, in FIG. 7, the area filled with hatching lines is the real object allocation area. At this time, the position of the coordinate point at the corner of each real object allocation area is also calculated. This calculation is performed based on the coordinate position of each point in the wall surface in the absolute coordinate system obtained in step 4 in the flowchart of FIG. In addition, when pasting the real thing, since the coordinate position is memorized for the frame of the window in the wall surface, and the points at both ends of the upper, lower, left and right sides of the wall surface, each real allocation area is the portion of the window frame or When it is included in each side, each real allocation area ends in the window frame and each side.

  In step 12, the area other than the real allocation area is set as the cut allocation area among the areas partitioned in a grid pattern. In addition, since the coordinate position is memorize | stored in the frame of the window in a wall surface, and the point of the both ends of the upper and lower sides of a wall surface, each cut allocation area | region will be included in the part and each side of the window frame. In such a case, it is assumed that each cut allocation area ends in the window frame or each side.

  In step 13, a cut allocation area in which cuts are allocated first is set. As this setting method, it may be from the above-described true assignment start point P or from the wall surface origin O. In this description, the wall surface origin O is set as the cut allocation start point, the allocation of cuts is started in order upward from this cut allocation start point, and all the allocation is performed in the upward direction. The order is to be assigned to the cut allocation area on the right side of the allocation start point. This order may be determined arbitrarily.

  In step 14, the vertical dimension and horizontal dimension of the set cut allocation area are calculated. In this calculation method, calculation is performed from the coordinate points of the corners of the cut allocation area to be allocated. Then, the cut data corresponding to the cut allocation area is retrieved from the cut data storage device 28 and called.

  Note that this step is omitted because there is no cut data at the first position of the south elevation. However, since this cut data exists in the allocation of cuts in the second cut allocation area in the south elevation and the allocation in the east elevation, west elevation, and north elevation, Search from among them.

  The “cut allocation condition” for performing the search is a cut having a horizontal dimension and a vertical dimension larger than the horizontal dimension and the vertical dimension of the cut allocation area as the first condition, and the cut as the second condition. Searches for the horizontal dimension of the allocated area, or the vertical dimension and the horizontal dimension of the cut, or the smallest difference between the vertical dimensions.

  In step 15, when there is no cut having a horizontal dimension and a vertical dimension larger than the horizontal dimension and the vertical dimension of the cut allocation area which is the first condition of the cut allocation condition, it is determined that there is no corresponding cut. To do. If there is a cut that meets the first condition, the process proceeds to step 16.

  In step 16, it is determined whether or not the corresponding cut can be allocated to the cut allocation area with the size. If the cut can be allocated with the size, the process proceeds to step 17; Then go to step 19. This determination is made by comparing the vertical dimension and horizontal dimension of the stored cut with the vertical dimension and horizontal dimension of the cut allocation area.

  In step 17, since the cut can be allocated as it is, the cut is allocated to the set cut allocation area, and the cut identification number of the cut is stored in the cut allocation area. .

  In step 18, the cut identification number of the allocated cut is deleted from the cut data storage device 28, and the process proceeds to step 30.

  In step 19, since it is determined in step 16 that the cut cannot be allocated with its size, the cut is cut corresponding to the cut corresponding area.

  In step 20, the cut cut is allocated to the set cut allocation area. Then, the cut identification number of the cut assigned to the cut assignment area is stored.

  In step 21, the cut identification number of the allocated cut is deleted from the cut data storage device 28, and the process proceeds to step 22.

  In step 22, it is determined whether or not the remaining part of the cut can be newly registered as a cut. If it can be registered, a new cut identification number is assigned in step 23, and the vertical dimension and The cut dimensions are stored in the cut data storage device 28 together with the horizontal dimension, and the process proceeds to Step 30. If the remaining part cannot be registered as a cut, the data is discarded in step 24 and the process proceeds to step 30. Here, the “cut judgment condition” that is a judgment condition as to whether or not the remaining portion can be registered as a cut will be described in detail later.

  In step 25, since it is determined in step 15 that there is no corresponding cut, a new real piece is cut corresponding to the set cut allocation area.

  In step 26, the cut piece is assigned to a cut assignment area. In this case, a newly created cut identification number is assigned.

  In step 27, it is determined whether or not the remaining part of the cut real thing can be registered as a cut object. This determination method is the same as the cut determination condition in step 22, and will be described in detail later. If the cut condition is met, the remaining portion is registered in the cut data storage device 28 as a cut. In this case, the newly created cut identification number, vertical dimension, and horizontal dimension are registered. On the other hand, if it does not meet the cut condition, it is discarded in step 29.

  In step 30, since the cut is allocated to one cut allocation area, it is determined whether or not to go to the next cut allocation area. If cuts are assigned to all the cut allocation areas in the south elevation, the process proceeds to step 31; otherwise, the process returns to step 14.

  In step 31, since the real thing and the cut are allocated to all the real thing allocation area and the cut allocation area, the south elevation of the state is displayed on the display device 14. In this case, as shown in FIG. 7, as the display state, the direction (for example, “south”) assigned to each area, the true object identification number, and the cut object identification number are stored.

  Then, this allocation process is performed in the order of the east elevation, the west elevation, and the north elevation in order from the south elevation. At this time, cuts are handled in the south elevation, and cuts that are not used in the south elevation are used for allocation in the east elevation. Cuts that were not used in the south elevation and east elevation are used in the west elevation, and cuts that are not used in the south elevation, east elevation, and west elevation are north. Used in elevation. Eventually, cuts that were not used in the south, east, west, and north elevations are discarded.

  As described above, in this allocation process, the real thing is assigned first, then the cuts are assigned in order, the cut that best matches can be assigned without waste, and further, in the order of south, east, west, and north. You can use cuts without waste. Therefore, the number of outer wall materials to be used can be minimized, and the cost can be reduced.

(5) Cut determination conditions Next, the cut determination conditions used in Steps 22 and 27 will be described. The cut determination condition varies depending on the type of the outer wall material to be attached, and will be described separately.

(5-1) First Cut Determination Condition The first cut determination condition will be described with reference to FIGS.

  As shown in FIG. 8, the outer wall material used in the first cut determination condition has a groove 32 on the lower side of the outer wall material 30, and a protrusion 34 corresponding to the groove 32 exists on the upper side. And when attaching this outer wall material 30, the groove | channel 32 of the upper outer wall material 30 is fitted in the protrusion 34, and it affixes in order. For this reason, when the outer wall material 30 is attached, the grooves 32 and the protrusions 34 are always required. Also, those with inclined surfaces cannot be handled and are discarded.

  In FIG. 9, a condition for determining whether or not the part remaining from the real object 36 is the cut piece 38 or the discarded part 40 will be described. In FIG. 9, the range indicated by hatching is the range of the cut piece 38, and the range indicated by cross hatching is the portion 40 to be discarded. The same applies to FIG. 10, FIG. 12, and FIG.

  FIG. 9A is a front view of the real object 36.

  In FIG. 9B, only the upper right part of the real object 36 is cut, and this cut part is a part 40 to be discarded because it does not have the groove 32 on the lower side.

  In FIG. 9C, the center portion of the real object 36 is cut, and the lower side of the cut portion is the portion 40 to be discarded because it does not have the groove 32.

  In FIG. 9D, the central portion of the real object 36 is cut into a rectangle, and the cut portion is a portion 40 to be discarded because it does not have the groove 32 and the protrusion 34.

  In FIG. 9 (e), the right half of the real object 36 is cut, and the remaining part also has a groove 32 and a protrusion 34, and thus becomes a cut 38.

  In FIG. 9 (f), the upper portion of the left half is cut, and the cut portion does not have the groove 32, and thus becomes a portion 40 to be discarded.

  In FIG. 9 (g), the left half is obliquely cut from the state of (e), and since this cut portion has an inclined surface, it cannot be diverted to other portions, and is therefore discarded. To do.

  In FIG. 9 (h), the upper part of the real object 36 is cut, and this cut part does not have the groove 32, and thus becomes a part 40 to be discarded.

  In FIG. 10, it is a figure which shows the state which judges whether the remaining part of a cut can be made into a cut.

  Similarly to the real object, the cut object is determined by whether or not the groove 32 and the protrusion 34 are present, and an object having an inclined surface is a portion 40 to be discarded because it cannot be handled.

  In FIG. 10A, the upper half is the discarded portion 40, the right half in FIG. 10B is the cut piece 38, the upper left portion of FIG. 10C becomes the discarded portion 40, and the upper right portion of FIG. The part becomes the discarding part 40, and the cut part of the central part in (e) becomes the discarding part 40.
