Select the 'Annotation Move' button from the Linear Draft toolbar and follow the prompt to select an annotation.
Select the span & versine that you want to move.
Move the span & versine to the location you want to place it.
Left click to accept. The span & versine will now be visible in its new location.
N.B. Span & versine annotation will always stay central to the structures that it is annotating, therefore only allowing up/down sheet movement.
