RotateRO

Turns the selected elements about a point. Walls take their doors and windows with them.

How it works

1. Started with nothing selected, Rotate asks for the elements: pick them, for example with a window selection from left to right, then press Enter.
2. Click the centre of rotation, or type it as x,y.
3. Click a point: the elements turn by the angle between the x axis and the line from the centre to that point. Or type the angle in degrees, counter-clockwise; a negative number turns clockwise.
