on live images and may only be performed with Optibeam ON.
Controls
This facility comprises a line (identified by the symbol 3Dn) with three location
points
p1 p2 p3
301
The measure~nt object may be moved (dragged) when in move mode or the
individual measurement points (pl,p2,p3) may be adjusted in position.
Associated with the objects is an annotation panel loaded from file 3Dn.ANN
containing the measurement parameters which are:
3Dna : apparent distance
3Dnb : depth of plane
3Dnc : actual distance on plane
3Dnd : slope of plane
3Dne : true depth of feature
Where n is the instance identifier (i.e. 1 for first object created, 2 for second etc
up to the limit pennitted)
The dimensional measurements are derived from the zone magnification hence
in situations where multiple zones are present all points must lie in the same
zone. If a point is moved so that it is in a different zone the parameter values are
set to zero and a 'BEEP' given.
