This tab allows you to modify one or more lines by entering new coordinates or property values. If one line is selected, the current values will be displayed in the spin boxes. However, if you have several lines selected, only the values that are common will be displayed.
You can modify the lines by editing the values in any of the spin boxes. If you alter the Length, the start and end values are recalculated by extending or trimming the entities by equal amounts at each end.
