Flip helix

The same helix can be drawn in two different ways on the page (mirror images). A helix drawn one way, cannot be changed to the other using rotation. The flip option will flip the helix to its mirror image. The latter is often necessary to create a clear drawing of pseudo knots. Menu:Geometry.Flip Drawing Tcl routine:flipall

The structure models are by default drawn clockwise. You can flip the entrire drawing so that is drawn counter-clockwise.
