I'm recently trying to design a flex PCB. I haven't been able to find any specific tutorials on how to do this in Altium. But I did find Altium blogs detailing some of the best design practices for rigid-flex PCBs.
One thing that I haven't been able to replicate is the hexagonal hatch that they say enhances flexibility. I've trying to do this through polygon pour without any luck.
I would like to know if anyone has managed to achieve this type of hatch! Thanks!
