1. ID number (
id
, starting with 0 ), quality value (
qu
, see below) number of buttons
(
nbt
) and the radius of the Measurement Tool tip sphere (
rd
).
2. Measured position (
s
i
) of the tip
3. Rotation matrix (
b
i
) of the tip orientation.
4. Button (

) of the position of the tool tip (in
mm

)
•
The quality (
qu
) can (so far) just get the values 1 . 0 and
−
1 . 0 .
−
1 . 0 means that the
target of the Measurement Tool is not visible at the moment.

Only available, if the Measurement Tool license is present for
DTrack2 (available since version v2.2.0)
The output for Measurement Tool references is defined as follows:
•
The first number gives the number of defined Measurement Tool references.
•
The second number gives the number of tracked Measurement Tool references.
•
The data of each tracked reference show up in blocks (three consecutive
[]
), like:
[id qu][
