I have a footprint that has some rather large, rectangular pads. The pads are connected to some templates with 12 spokes each. Setting the Orthogonal Spokes feature in DFM/DFT Rules doesn't make a difference – the spokes are still angled towards the center of the pads. See attached screen shot.
Can I assume that you have placed the attribute on the pads? I have created a test piece myself with a large pad, not sure the details of your pad, and it behaves as I would expect, using settings like those shown in your picture.
Yes, the thermals have the attribute StrongThermal – in order to give them 12 spokes. The attribute doesn't have a value, though. But as far as I know, a value shouldn't be necessary. Should I send some more details, or do you want the whole design?
Btw, the pad is a 95 × 133 thou rectangle, with a 32 × 70 thou oval hole.
