9.5.6 Persistence of 3D Measurements and Markups 72
A3
array
(
Required for arcs only; ExtensionLevel 3
) A three-element array of
numbers that defines the start of the arc being measured. This entry is
required if the geometry being measured is an arc. See
FIGURE 9.26
for a
visual representation of
A3
.
A4
array
(
Required for arcs only; ExtensionLevel 3
) A three-element array of
numbers that defines the end of the arc being measured. This entry is
required if the geometry being measured is an arc. See
FIGURE 9.26
for a
visual representation of
A4
.
TP
array
(
Required; ExtensionLevel 3
) A three-element array of numbers specifying
the text anchor point for the measurement value string.
TX
array
(
Required; ExtensionLevel 3
) A three-element array of numbers specifying
the horizontal direction vector for the text string presenting the
measurement value string.
TY
array
(
Required; ExtensionLevel 3
) A three-element array of numbers specifying
the up direction vector for the text string presenting the measurement
value string.
EL
number
(
Optional; ExtensionLevel 3
) The length of the extension line in points.
The default is 60 points.
TS
number
(
Optional; ExtensionLevel 3
) A number representing the measurement
text string height defined in points in the default user space. Note that
measurement text is zoom invariant.
The default is 12 points.
C
array
(
Optional; ExtensionLevel 3
) An array of three numbers in the range 0.0
to 1.0, representing the RGB color of the measurement markup.
The default value is the array
[1 1 1]
, representing the color white.
V
number
(
Required; ExtensionLevel 3
) A numeric value representing a
measurement value. This value is converted to a text string and
displayed as part of the measurement text string.
U
text string
(
Required; ExtensionLevel 3
) A string representing the units for the
measurement.
P
integer
(
Optional; ExtensionLevel 3
) The number of decimal digits, which
represents the precision, shown for the measurement value (
V
).
The default to
3
, if
P
is not specified.
UT
text string
(
Optional; ExtensionLevel 3
) A string defined by the user that is
appended to the end of measurement value string. If omitted, no string
is appended.
