Reduce clearances/thermal relief between shapes and clines

Fras

Hello,

I'm using allegro 16.6 and I'm having some difficulty with clearances between certain shapes:

From my screenshot, I'm trying to connect all the areas in red together (they are all RXGND). Is there something I should be using such as global parameters or some box i need to tick for these smd pads to be covered?

Cheers, 

Fraser

    I think your problem is that your shape is just missing the center of the pad by just a tiny fraction. I always use C-Lines to connect the pads, even if the c-line is REALLY small. I'm not sure what spacing I'm looking at here, but taking a 5 mil trace (anything more than 0 really) and connecting the pads directly will remove the rat, and then you can draw the shape on top of that. The other option would be to edit your shape so that it fully covers the center of the pad. It also needs to cover the center point of the C-Line when you connect to the C-Line, or you will have a similar problem there too.
