gvSIG-Desktop 1.12. Manual de usuario
You can use this tool to rotate the selected objects by taking a base point as the centre. You can activate this tool by clicking on the “Rotate” button in the edition tool bar
or by going to the "Geometry" menu bar, then to “Modify” and “Rotate”.
To rotate an element, first place the base point by clicking on the graphic area. Move the mouse, with the help of the projection that gvSIG uses to the effect, until the new position has been established.
Left click on the mouse in the view to define this point.
If you wish to rotate an element from the command console, select the object to be rotated, write the command “rotate” and input the first move point.
Then input how much you wish to rotate it in sexagesimal degrees.
The object will be rotated clockwise if you write a negative angle and anti-clockwise if you write a positive angle.
