I use Altium Designer. I need to have several connection types in the same polygon. some component direct connection and some components relief connection.
how can I do it?
I do not use thermal relief on outer layers on SMD pads, never. Many SMPS SMD designs require a good connection both for current requirements and thermal requirements (getting heat away from the components). PTH components will be decided by the amount of copper connected and on how many layers the PTH pin connects to the copper.
I do not know the exact method of choosing whether thermal relief is used on a pad or not in Altium...
