In the 3d curves pocketing machining like "<SPIRAL>" it is now possible to set more than one "zone" in the same machining. For instance it is possible to input, inside the machining's name, the words: <SPIRAL0/5/0.05> <SPIRAL5/0/0.15> to set which kind of machining to execute: with 0.05 mm increment for the first 5 millimetres of the cavity, starting from the "prep-line", and with 0.15mm increment for the rest of the cavity. The parameters of the "<SPIRAL...>" strategy are 3: start, end and increment. The start and the end can be negative, in this case the machining will begin from the back instead of the border.

In this picture we set 0.05 for the first 3 mm and 0.2 from 3mm to the end of the cap. Also this Strategy can be downoaded from the website.
