1.3.2. Segment Stretching

In some cases it may be useful to adjust the length of a single figure segment on its own. This can be used to create simple 3D effects or to give the impression of a stretchy object.
    This can be done by holding down the Ctrl key on the keyboard while dragging a red handle or by enabling the option in the canvas toolbar. The segment handle will then follow the cursor position without being constrained to its default length. This can be useful for creating realistic movements for deformable or stretchy objects as well as creating the effect of 3D movements.

Stretch Snapping

If Ctrl dragging a segment from a non-default length (the length that the figure type was designed with), then it will snap back to its default length when the cursor is close enough. It won't snap to the default length if the drag is begun from the default length. If the segment is a non-default length and you wish to position the segment close to the default length then it will require two drags of the handle. Firstly drag the handle so that it snaps to the default length, then release the mouse and drag again to the length you require.
  Alternatively, disable the snap option in the canvas toolbar.
Snapping of segment length does not happen in the figure builder because that's where the default segment lengths are defined.
