Hello there , a via stitching is it used just for cooling a component (regulators for exemple ) or it has other utilisations . Also, a stitching via should has a net name or i can let it "no net" ???

Via stiching is used to either:
- Help cooling
- Connect net on differing layers, primarily Gnd
And yes, the via needs to be in a net. Altium automatically assigns a net if the via is placed on a trace (not a polygon!) -
I would like to add, via stitching may have number of different reasons.
For example GND stitching VIAs can be used to control return currents (some time ago I made a video on this topic: How GND VIAs Improve Your PCB Layout https://youtu.be/nPx2iqmVAHY ). Or in RF they can help to create waveguide, they may be important when designing PCB antennas or they can help with EMC/EMI etc ....Comment
