Hi,

Any idea please how to mark Thermal Cut in side the PCB?
For your reference I have attached a sample PCB drawing showing my requirement. I searched and didn't find the relevant post, hence this query.

Regards,
Pradip

What do you mean by "Thermal Cut"? Are you referring to a void in an inner layer's dielectric material? A standard board cutout? A void in a copper pour?

If so, then I guess one way to do this would be to create another mechanical layer and give it a descriptive name (e.g. "Dielectric Void (Inner 1)"), select it in the Current Shape and Text Layer drop-down list at the top of the screen, draw the void shape in the desired location and contact the board house to make sure they have that capability and to see if they need any other documentation. You will also need to surround the void with a Route Keepout shape (e.g. on the normal signal layer named "Inner 1") that is a little larger than the void to keep any copper away from its perimeter.
