The Isolate values for Thermal and Annulus determine the width of the
thermalbridgeorring.
The Restring option determines whether the insulation bridge of the
thermal symbol should be drawn immediately at the edge of the hole or
at a distance from the hole given by the restring value (Restring tab, In

The isolate value for Thermal also applies to polygons. It determines the
distance between a polygon and the restring of the pad or via that is
joinedtothepolygonthroughathermalsymbol.
The Generate thermals for vias flag permits thermal symbols at through-
holecontacts.Otherwiseviasarefullyconnectedtothecopperplane.
