Whenever you add a span & versine annotation, Lineardraft will calculate the span and versine, then draw the annotation.
As you work on your design, changes you make will cause span & versine annotations to become out of date. When this happens Lineardraft will recalculate them.
Span & versine annotations could be recalculated because:
- A structure has been moved
- A structure or structures have been multi-moved
- A structure’s tracks have been reassociated
