3D Measurement/Markup Dictionary
The entry of
MA
dictionaries, where each dictionary represents an instance of a 3D measurement to be displayed in the
context of this view. Each 3D measurement dictionary describes the type of the 3D measurement through
the
Subtype
of a conforming reader.
The entries of the 3D Measurement/Markup dictionary are described in the table that follows.
KEY

TRL
The field contains the current name for the measurement markup. Each measurement markup is
TRL
assigned a name ("Measurement 1", "3D Comment 22", ...and so on) when it is created. These names may
be shown by an interactive conforming reader so that users can see what measurements are associated
with what views. Users can override the initially defined names at any point.
