GND pads not connecting to GND polygon?

mastermatic
mastermatic over 10 years ago

Hi, I'm trying to create a 4 layer PCB (TOP + POWER + GND + BOTTOM). I created 2 planes for the VBB and GNDBB using polygons.

My problem is the connection (let's say) beetween a resistor and the PAD of a component (let's call it X component). If try to connect the VBB connection of the resistor to a Via (and the via's name is VBB) the VBB PAD of the X component with appear like the pic below and the airwire that was connecting the resistor to the X component is gone!

But if I try to do the same with a resistor that is connected to a GND pad, the pad stays the same and the airwire is still there, which makes me wonder if the vias are even connecting to the GND plan.

 

The following are printscreens of the settings I'm currently using.

What am I doing wrong here?

Any help would be highly appreciated!

    I'm not sure I understand the question.

     

    Just make sure the through hole GND pad is surrounded by a polygon named

    GND. A SMD resistor pad needs a via closeby to get to inner layer.

    And remember to do ratsnest.

    So, the GND pad on the X component? Like JP2 component on the last picture?
