Some Flex-Rigid PCB manufacturer ask for no trace bending within 2mm vicinity of bending line, and we have to keep trace straight in that 4mm boundary, I was wondering do we have an option in AD to set and check this as a DRC rule?

I do not really know how altium would be figuring out if a track is straight. I have not seen any rule like that.

Hi,
I used to think that PCB is two forms either rigid or flex, but it looks the third form also exists as one-tine bending; wondering did you hear about it?

Eurocircuits has a "semi rigid" which can be bend about 5 times.

I didn't know that. Interesting.

I am wondering can we set different design rules for different board sections?
For example, I need more spacing in flex parts than what is set for the rigid section.

Dear @qdrives ,
Thank you for comment and help, I also find that AD20 has an option for flex and rigid sections,
Of course, the ROOM option is more helpful.
