# Roof Design - Move Line

The "Move Line" function allows an entire roof skin line to be moved. The two adjacent roof skin lines of the same roof surface are then always extended or shortened accordingly. It then appears, for example, as follows:

The verge lines of the modified roof surface are extended.

By shifting the eaves line, the ridge lines are extended. The eaves of the adjacent roof surfaces remain unchanged.

For this function, simply select the line to be moved. No additional points are required here, since the entire line is always moved. Next, the selected line can be moved graphically and placed at the desired position. All snap and input functions are available for this. After placing the line, a dialog box opens in which you can correct the position of the line once more. When any number is changed, the other numbers adjust automatically.

**Batten spacing / covering width of standard tiles:** If tiles have been entered on the roof, you can adjust the position of the line to the covering length or covering width of the tiles. Depending on which line you moved (e.g., eaves or verge), the text will change accordingly. If the line does not run parallel to the slope direction of the roof surface (verge) and not perpendicular to the slope direction (eaves), adjustment to the tiles is not possible. In that case, it is also no longer reasonable.

> The covering length or covering width of the tiles used is automatically specified here. However, the value can also be changed.

**Number of tile rows:** This field indicates the number of tile rows. Immediately after moving the line, this is usually a fractional value, and therefore the field is highlighted in red as a warning. Using the plus and minus controls at the right end of the field, the value can be increased or decreased. The value is always adjusted to an integer, and the red highlight disappears.

**Shift within the roof surface:** This value shows the distance of the new line to the old one, measured along the slope of the surface.

**Horizontal displacement:** This shows the displacement in plan from the old position to the new position of the line.

**Vertical displacement:** This value indicates the height difference between the old and the new position of the line.

**Elevation of the line:** This field displays the absolute elevation of the new line, measured from global 0.

### Note:

This function works somewhat differently from the "Rectangle" function in the classic program. With that function you moved an entire line or a part of a line. In both cases, the adjacent lines were not extended; instead, new line segments were created. If previously you had moved the entire eaves of the hip roof (see above), the ridge lines would not have been extended; rather, a rectangular enlargement of the roof surface would have resulted.

If you want to pull the entire line in the current program so that a rectangular enlargement is produced, use the "Move Partial Line" function, even though you want to move the entire line. Select the line and then use the start and end points of the line as the boundary points.

The current approach is more consistent and enables easier enlargement of hip areas or other roof surfaces with oblique lines. This would have been possible before as well, but with greater effort.
