Most shapes have handles in the top, center, bottom center, left middle, and right middle that allow the figure to be stretched and made wider or taller. The screenshot below demonstrates these handles for a rounded rectangle.
To Stretch a Figure, click on one of the above shown handles and drag it to a desired location. The figure will stretch itself dynamically as the handle is dragged.
When the Selection as Group (Default) option is enabled, and multiple figures are selected, all figures can be stretched at the same time by touching and dragging on the same handles for the selection group, as shown below:
Tip: Pressing the Shift Key as a figure is stretched allows its current aspect ratio to be maintained.
Note: Multiple figures can be stretched at once by placing them into a group.
