Polygon not connecting to Pad

dbemmann

Strangely the pads of my component are not connecting to polygons of the same net. Why?

 

The component (J2 on the screenshot) is a self-designed solder-jumper defined as a net tie. On this PCB I want to use it to connect two ground planes (polygons with nets GND and AGND). As you can see, CircuitStudio doesn't connect the pads to the polygons.

 

Both polygons are set to "pour over all same net objects". I have two design rules for "polygon connect style":

Priority 1: first object = via, second object = all, connect style = direct connect

Priority 2: first object = all, second object = all, connect style = relief

 

You can both of them working on the other pads, but strangely not on the solder-jumper. On the other hand, these fine unrouted lines show that it should be connected. What am I doing wrong? Just for completeness, the component is built with 4 pads (two rounded ones overlapped by two rectangular ones). In any case there is enough room for relief lines.

    A little update on this: I tried what happens when I remove the connecting track between the pads (in the component). Interestingly, then the pads connect to the polygons with relief, just as expected. But that's not a solution since the component is no longer a Net Tie now, and I cannot place that connecting track in the PCB editor either.

    Try switching off the polygons (unpoured), then place a track from large GND pad to Net-Tie GND pad.

    Also from large AGND pad to AGND Net-Tie.

    Then try re-pour all, with "Pour over same net objects" enabled.
