    Try setting the Thermal Connections to "Full Contact" before autorouting, Shapes>Global Dynamic Params, Thermal Relief Connects tab, set the Thru Pins to Full Contact. Also don't add shapes the layers that the autorouter is going to use, before autorouting. If you need shapes on the layers that the autorouter is going to use, autoroute the layers first and then add the shapes and then edit the routing manually as required.

     Hello oldmouldy, the result is still same with full contact setting. auto router is using net via to implement fan out of all components (including through hole components for which spokes are to used. further more there are some static shapes on top layer and some manual routing which i have fixed before fanout. but all other shapes are on plane layers (stackup attached).

    please help
