I don't fully understand the source code and I don't know if anyone is interested but this is what I found.
Apparently there are 5 types of thermals: 1. a X shape with straight spokes 2. a X shape with round spokes 3. a + shape with straight spokes 4. a + shape with round spokes 5. a solid shape In the PCB file they are represented by: 1. a nothing 2. a "X" 3. a "+" 4. a "t" 5. a "S" The thermal SFlags attribute follows the structure: thermal(layer[spoketype],layer[spoketype],layer[spoketype]) So: Via[100000 100000 5500 2000 0 3000 "" "thermal(0X)"] is a via with a X shape thermal with straight spokes connected to layer 0. Via[100000 100000 5500 2000 0 3000 "" "thermal(1t)"] is a via with a + shape thermal with round spokes connected to layer 1. Via[100000 100000 5500 2000 0 3000 "" "thermal(0S,1-3+,4)"] is a via with: a solid thermal connected to layer 0, a + shape with straight spokes connected to layers 1 through 3, a X shape with straight spokes connected to layer 4 Thanks everyone.
