Basic operations

Selecting an object in a canvas

Select an object (i.e., a river transverse line or nodes of the grid that is displayed in the canvas) as follows:

  • Left click: Selects the object that is pointed at.
  • Left drag: Selects all objects in the rectangle made by the drag start and finish points.

Note that not all type objects support multiple selecting by left dragging. For details, refer to the description of each function.
