Circle Tool
Use the circle tool to create a circle.
The Circle tool is only available if the Cross section view tool is enabled.
The circle tool creates a circle by defining its centre and a point on its perimeter. To draw a circle activate the tool, define a point for the centre of the circle by left-clicking on the mouse and finally define a point on the perimeter of the circle. The new circle belongs to the group selected in the Select group drop-down list. To modify the object parameters afterwards use the Object Properties dialog.
