gvSIG-Desktop 1.12. Manual de usuario
You can draw an arc by clicking on the “Arc” button in the tool bar
or by going to the “Geometry” menu bar then to “Insert” and “Arc”.
Three points are requested to draw an arc. The first and last points mark the initial and final points of the arc and the second one marks an intermediate point through which the hypothetic circle of which the arc is a part would pass. To insert an arc from the command console, write the command “arc”. The three points required to define the arc will be requested one after another.
