Alphacam saw

I welcome the people!
Can someone tell me on this issue.
Need a conclusion of the angles in the strategy of "Saw".
As I understand it, the derivation of angles goes through the calculation of trigonometric equations
with the famous "unit vector".

I do not display a "unit vector" in all options of the "Saw" strategy
What am I doing:
I take a post-processor where I leave only a block of working moves
with the conclusion of a unit vector.

Sawing rectangles.
The vector is wrong, it does not change.

I put a checkbox so that you can cut arcs
Sawing a rectangle and an arc.
The vector is correct, changing.
