Displayed on the operation screen. The arrangement is from the inner surface of the left wall made of log material to the opening (hereinafter referred to as the left interval), the width of the opening, and from the inner surface of the right wall made of log material to the opening. (Hereinafter referred to as the right interval). Further, when it is necessary to specify the arrangement in the height direction, the height of the opening and the height from the floor to the bottom surface of the opening are shown. However, when the height of the opening and the height from the floor to the bottom surface of the opening are predetermined fixed values, these displays are omitted.
Each of these values is changed to a text box when the user selects a number with the pointing device, and a numerical value can be entered in the text box.
Similarly, the internal size (vertical length × horizontal width) of each unit is changed to a text box when the user selects a number with a pointing device, and a numerical value can be entered in the text box.

An opening is formed in the wall by selecting the basic opening specified by the basic opening information included in the basic opening table 220 with a pointing device and placing the basic opening on the wall and enlarging or reducing the basic opening. In this state, when the width of the unit or the width of the opening is changed, both the left interval and the right interval change in accordance with the change in the width of the unit or the width of the opening.
However, if the left interval is entered as a numerical value in the past operation, if the width of the unit is changed by an operation with a pointing device or a numerical input, or the opening width is changed by a numerical input, While the interval of is fixed at that value, only the right interval changes according to the change of the width of the unit or the width of the opening. In addition, when the right interval is input as a numerical value in the past operation, if the width of the unit is changed by the operation of the pointing device or the input of the numerical value, or the opening width is changed by the input of the numerical value, The distance between the left and the left is changed according to the change in the width of the unit or the width of the opening while the distance is fixed. When both the left interval and the right interval are input, the interval input last is given priority.

The layout consists of the distance from the inner surface of the upper wall made of log material to the opening (upper distance), the width of the opening, and the distance from the inner surface of the lower wall made of log material to the opening (lower ). Further, when it is necessary to specify the arrangement in the height direction, the height of the opening and the height from the floor to the bottom surface of the opening are shown. However, when the height of the opening and the height from the floor are predetermined fixed values, these displays are omitted.
Each of these values is changed to a text box when the user selects a number with the pointing device, and a numerical value can be entered in the text box.
The basic opening specified by the basic opening information included in the basic opening table 220 is selected by a pointing device and placed on the wall, and the opening is arranged by enlarging or reducing the basic opening. In this state, when the vertical length of the unit or the width of the opening is changed, both the upper distance and the lower distance change according to the change of the vertical length of the unit or the width of the opening.
However, if the upper interval is entered as a numerical value in the past operation, if the vertical length of the unit or the width of the opening is changed, the upper interval remains fixed at that value, and the operation or If the vertical length of the unit is changed by inputting a numerical value, or if the width of the opening is changed by inputting a numerical value, only the lower interval changes. Conversely, if the lower interval was entered as a numerical value in the past operation, the vertical length of the unit is changed by the operation of the pointing device or the numerical value input, or the opening width is changed by the numerical value input. Then, the lower interval is fixed to the numerical value, and only the upper interval changes according to the change in the vertical length of the unit or the width of the opening. If both the upper and lower intervals are entered numerically, the interval entered last takes precedence.
However, when the width of the opening is changed by an operation with a pointing device, the upper and lower intervals are controlled by the pointing device even when the upper interval or the lower interval is input in the past operation. Will be changed depending on.

In FIG. 7, the wall identification information is indicated by “wall under U1”, for example, but this is only an example, and the wall on which the opening is arranged may be specified by other methods such as three-dimensional coordinates.
In the case of an opening arranged on a lateral wall, the arrangement indicates a left interval, an opening width, and a right interval. In the case of openings arranged in a vertically oriented wall, the upper interval, the width of the opening, and the lower interval are shown.
For the interval input, in the case of an opening arranged on a horizontal wall, non-, left, or right is set. Here, “not yet” indicates that neither the left interval nor the right interval is input (not set). The left indicates that the left interval was last input (set). The right indicates that the right interval was last input (set). Further, in the case of an opening arranged on a vertically oriented wall, the interval input is set to not, above, or below. Here, “not yet” indicates that neither the upper interval nor the lower interval is input (not set). The top indicates that the top interval was last entered (set). The bottom indicates that the bottom interval was last entered (set).

At this time, the interval input of the aperture arrangement information is still “not yet”.

In addition, in the opening arranged on the sideways wall, when the left interval is selected and a numerical value is input to the left interval, the arrangement changing unit 106 sets the interval of the opening arrangement information stored in the opening arrangement table 260. Regardless of whether "Right" or "Left" is set in the input, the left interval is changed to that value, and the right interval is also changed according to the change. Then, the arrangement changing unit 106 changes the arrangement of the opening arrangement information stored in the opening arrangement table 260 and sets “left” as the interval input.
When the right interval is selected and the numerical value is input to the right interval in the openings arranged on the sideways wall, the arrangement changing unit 106 inputs the interval information of the opening arrangement information stored in the opening arrangement table 260. Regardless of whether "Right" or "Left" is set, the right interval is changed to the value, and the left interval is also changed according to the change. Then, the arrangement changing unit 106 changes the arrangement of the opening arrangement information stored in the opening arrangement table 260 and sets “left” as the interval input.
When numerical values are input to both the left interval and the right interval, the arrangement changing unit 106 inputs the interval information of the opening arrangement information stored in the opening arrangement table 260 corresponding to the last input interval. Set to “Right” or “Left”.

Similarly, when an upper interval is selected and a numerical value is input to the upper interval in the openings arranged on the vertical wall, the arrangement changing unit 106 sets the opening arrangement information stored in the opening arrangement table 260. Regardless of whether “up” or “down” is set in the interval input, the upper interval is changed to the numerical value, and the lower interval is also changed in accordance with the change. Then, the arrangement changing unit 106 changes the arrangement of the opening arrangement information stored in the opening arrangement table 260 and sets “up” in the interval input.
In the opening arranged on the vertical wall, when the lower interval is selected and a numerical value is input to the lower interval, the arrangement changing unit 106 inputs the interval of the opening arrangement information stored in the opening arrangement table 260. Regardless of whether “Up” or “Down” is set in the field, the lower interval is changed to the numerical value, and the upper interval is also changed in accordance with the change. Then, the arrangement changing unit 106 changes the arrangement of the opening arrangement information stored in the opening arrangement table 260 and sets “down” in the interval input.
When numerical values are input to both the upper interval and the lower interval, the arrangement changing unit 106 inputs the interval of the opening arrangement information stored in the opening arrangement table 260 corresponding to the interval inputted last. Set “Up” or “Down” to.

Then, the arrangement changing unit 106 changes the arrangement of the opening arrangement information stored in the opening arrangement table 260 to 400 + 600 + 1000, and sets “right” as the interval input.

In addition, in the opening arranged on the horizontal wall, the width of the opening is changed by inputting a numerical value in a state where “left” is set in the interval input of the opening arrangement information stored in the opening arrangement table 260. Then, the arrangement changing unit 106 changes only the right interval according to the change in the width of the opening while the left interval is fixed to the numerical value. Then, the arrangement changing unit 106 changes the arrangement of the opening arrangement information stored in the opening arrangement table 260.
When the opening width is changed by inputting a numerical value in the state where “right” is set in the interval input of the opening arrangement information stored in the opening arrangement table 260 in the opening arranged on the sideways wall, The arrangement changing unit 106 changes only the left interval according to the change in the width of the opening while the right interval is fixed to the numerical value. Then, the arrangement changing unit 106 changes the arrangement of the opening arrangement information stored in the opening arrangement table 260.

Similarly, in the opening arranged on the vertical wall, the width of the opening is changed by inputting a numerical value when “upper” is set in the interval input of the opening arrangement information stored in the opening arrangement table 260. Then, the arrangement changing unit 106 changes only the lower interval according to the change in the width of the opening while the upper interval is fixed to the numerical value. Then, the arrangement changing unit 106 changes the arrangement of the opening arrangement information stored in the opening arrangement table 260.
When the opening width is changed by inputting a numerical value in the state where “down” is set in the interval input of the opening arrangement information stored in the opening arrangement table 260 in the opening arranged on the vertical wall. The arrangement changing unit 106 changes only the upper interval according to the change in the width of the opening while the lower interval is fixed to the numerical value. Then, the arrangement changing unit 106 changes the arrangement of the opening arrangement information stored in the opening arrangement table 260.

  For example, when “lower” is set in the interval input of the opening arrangement information of the opening P2 (window W1) and the width of the opening P2 (window W1) is 2000 as shown in FIG. As shown in 20 (B), the user selects the number 2000 and enters the number 3000 in the text box. At this time, as shown in FIG. 20C, the arrangement changing unit 106 changes the upper interval to 900 mm while fixing the lower interval to 1900 mm. Then, the arrangement changing unit 106 changes the arrangement of the opening arrangement information stored in the opening arrangement table 260 to 900 + 3000 + 1900. At this time, the interval input of the aperture arrangement information remains “below”.

When the user selects an in-unit module arranged in the unit on the operation screen with the pointing device, the arrangement changing unit 106 reads out the in-unit module arrangement information of the in-unit module from the in-unit module arrangement table 270. Then, as illustrated in FIG. 12, the arrangement changing unit 106 displays the arrangement of the modules in the unit included in the read module arrangement information in the unit on the operation screen. The arrangement includes an upper interval, a lower interval, a left interval, and a right interval with the size of the module in the unit (vertical length × horizontal width) as the center. Furthermore, when it is necessary to specify the arrangement in the height direction, the height of the module in the unit and the height from the floor to the bottom surface of the module in the unit are included. However, when the height of the module in the unit and the height from the floor to the bottom surface of the module in the unit are fixed values set in advance, these displays are omitted.
When the user selects with a pointing device and selects the number of modules in the unit (vertical length x width), top spacing, bottom spacing, left spacing, or right spacing, the layout changes.
