Measurement of an oblique angle (measurement type 24)

Measurement method for converting a measuring point in any coordinate system
Coordinate transformation of a position ($AC_MEAS_TYPE = 24)
With this method of measurement, a measuring point in any coordinate system (WCS, BCS,
MCS) can be converted with reference to a new coordinate system by coordinate
transformation.
The new coordinate system is generated by specifying a desired frame chain.
