Rotate

The 'Rotate' function allows any number and combination of lines to be selected with the crosshair. The right mouse button ends the selection of lines to be edited and the base point for the rotation is requested. After choosing the base point, the relative rotation angle can be specified. The rotation principle is that the defined rotation angle is applied about the chosen base point. To rotate counterclockwise, the rotation angle must be specified with a negative sign. The distance and position of the selected lines relative to each other remain preserved after the rotation is executed.

All known graphical and temporary auxiliary functions are available for defining the base point.
