Description
Reference point X ∅ (abs, always diameter)
Reference point Z (abs)
Thread pitch 1
● Intermediate point 1 X ∅ (abs) or
● Intermediate point 1 in relation to X0 (inc) or

● Intermediate point 2 X ∅ (abs) or
● Intermediate point 2 in relation to X1 (inc) or
● Thread taper 2
Incremental dimensions: The sign is also evaluated.
● Intermediate point 2 Z (abs) or
● Intermediate point 2 in relation to Z1 (inc)
Thread pitch 3 (unit as parameterized for P0)
● End point X ∅ (abs) or
● End point 3 in relation to X2 (inc) or
