Defining the working plane with the spatial angle:
PLANE SPATIAL
Application
Spatial angles define a working plane through up to three rotations
in the non-tilted workpiece coordinate system
B-C).
Most users assume three successive rotations in the reversed
order (tilting sequence
The result is identical for both perspectives, as the following
