Before you start
Steps
- In the 「計算条件」 panel at the bottom left of the screen, enter a number in 「敷地面積」, 「前面道路幅」 or 「隣地境界距離」. To the right of each field, the unit is shown, followed by 「既定 {既定の値}」 while the field is empty or 「入力値」 once you have entered a value. 400 milliseconds after you stop typing, the reference volume is recomputed with the new value.
- To return to the defaults, click 「既定に戻す」 at the top right of the panel. The three fields are emptied and the volume is recomputed with the defaults.
「既定に戻す」 is shown only while at least one field has an entry. The values you enter are also used for the reference volume of scenarios you run afterwards.
How to check
The inputs line in the panel at the bottom right of the screen shows the values for the site, the road and the distance to boundary, each marked 「入力値」 or 「既定」. When all three are defaults, it reads 「敷地・前面道路は入力値（既定 500 m² / 8 m）、隣地境界距離は既定 3 m」. The box at the scenario's location is replaced by a box computed with the new values.
If it does not work
Entering values before running a scenario does not compute a reference volume. During a prediction, the fields and 「既定に戻す」 cannot be used. For what to do about each line in the panel at the bottom right of the screen, see Troubleshooting.
