Getting a static shape in part symbol to connect to a net

Mattski

I have a board with a lot of RF connectors, and 5 different ground nets for different board sections.  The footprint for the RF connector has 2 ground pads, and one signal pad, and also some static shapes connected to the ground pads that will make the signal pin coplanar waveguide.  I have defined those shapes seperately because it needs to be a precise width, and the spacing is a precise amount that I don't want defined by the constraint manager.

For most of my board it recognizes these static shapes as belonging to the ground nets where it is physically connected to the connector ground pins, and thus it properly connects it to the ground pour that I have on the top layer.  On some sections of my board, it is only showing up as belonging to the Dummy Net on Etch/Top, and thus the ground pour is not being fully connected to this static shape - it is using the shape-shape spacing rules to put a void in between. This is still the case when I have a ground via connecting this static shape to the ground plane beneath it.

I have tried re-netlisting the design,refreshing the symbol drawing, updating shapes to smooth, checking shape outlines in DB Doctor, derive connectivity, and save-exit-reopening, but it is staying as Dummy Net. I know that I could redraw the symbol drawing and create a pad which I draw to be this irregular shape.  I would prefer not to do that since it takes quite a bit longer, and the static shapes have worked properly at least in some sections of my board - I just don't know why yet.

 What do I do to get these static shapes to show up with the net of the pin that they are overlapping?

     Sounds like you're doing it right so without seeing the board  I don't know what's wrong.
    For the time being select the shape manually and assign the net.  Should clear up.
