Distance
Measuring distance in
Cinderella is very much like drawing a line in
add a line mode. You have to select the two points whose distance from each other you want to measure. This is done with a single mouse press–drag–release sequence.
- Move the mouse pointer over the first point and press it.
- Drag the mouse, with the left button pressed, to the second point. While you drag, a ruler with the actual distance from the first point to the mouse pointer is shown.
- The ruler snaps to selected points. When the second point is selected, you can release the mouse button.
