FIG. 11 shows an example of a method for displaying the position of the opening.
When a user selects (for example, clicks with a mouse) an opening arranged on a wall that extends horizontally on the operation screen (hereinafter referred to as a horizontal wall), the horizontal arrangement of the opening is changed. 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.
However, if the opening width is changed by an operation with a pointing device, the left and right intervals are controlled by the pointing device even if the left interval or the right interval has been input in the previous operation. Will be changed depending on.

Similarly, when the user selects an opening arranged on a vertically extending wall (vertical wall) on the operation screen with the pointing device, the vertical arrangement of the opening is displayed on the operation screen. 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 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.
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, when the upper interval is input as a numerical value in the past operation, the vertical length of the unit is changed by the operation by the pointing device or the input of the numerical value, or the opening width is changed by the input of the numerical value. And the upper gap remains fixed at that value, and only the lower gap 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.

The opening arrangement table 260 in FIG. 7 stores opening arrangement information indicating the arrangement of each opening. As shown in FIG. 7, the opening arrangement information includes opening identification information, basic opening identification information, wall identification information, arrangement, and interval input.

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).

For example, the opening P1 shown in FIG. 8 is a door. The dimension of the opening P1 is a standard dimension determined by the manufacturer. The opening P1 is arranged on the lower wall of the unit U1. The left interval, width, and right interval of the opening P1 are 700, 600, and 700, respectively.
Further, the opening P3 shown in FIG. 8 is released. The opening P3 is disposed in the wall between the unit U2 and the unit U4. The left interval, the width, and the right interval of the opening P3 are 1000, 1000, and 2800, respectively.
