Usage Steps
Click on the edit walls icon.
Select the walls you want to change by clicking on them with the left mouse button.
If you want to change the wall's angle in length or plan, it is important where you click on the wall. If you click on a point near the left end of the wall, the left end of the wall is fixed, if you click on a point near the right end, the right end of the wall is fixed, if you click on a point near the middle of the wall, the middle point of the wall is fixed. This point is kept fixed (its position does not change) during length or angle changes.
Click the right mouse button. The Wall Parameters dialog will appear.
Select the wall by clicking on the left end of the wall.
Change the length of the wall. The wall will lengthen or shorten to the right.
Change the angle of the wall. Your wall will rotate by accepting the wall left node as the center.
Exit the dialog by clicking the OK button with the left mouse button. The changes you make will be applied to the wall(s) you have selected.
