Snapped Objects

    You can assign arrows to the control point of the shapes. (It means that when you drag the shape, the arrow will be pointing to the same control point on the dragged object.)

    This feature can be useful especially when one wants to highlight the steps of a mechanism, or during drawing charts.

    Draw Snapped Objects

    Select one of the Arrow/Reaction tools, then drag from one of the control points of the first shape to the control point of another object. (When the mouse cursor is close enough, the arrow snaps automatically to the nearest point.)

    Modify Snapped Objects

    When you want to disconnect the arrows from the boxes, you just need to drag the end of the arrow away from the box. (Hovering over with Arrow or Selection tool, blue circles appear at the end of the arrow to show the area where to start dragging.)

    Delete Snapped Objects

    Selecting the whole structure by using the Delete tool, you can delete snapped objects from the canvas.

    However, erasing the box results that the attached arrow will remain on the canvas, pointing to its original direction.
