It could be the shape area around the pin, try adjusting your pull back,
some trail and error inputs for the smd/ thru pin, via, cline, shape
etc....you might try setting all to zero, then tweak it out 10 mils at a
time.
Although you want 8, you can't always get it, due the area around the
pin, and depending on how much the pull back is,

        Hi folks,

        I have a surface mount DC-DC Converter with round pads which I
would like to connect to a top surface plane with an 8-way connection. I
can get it to work if I choose the "8 way connect" under the shape
parameters for smd pins, but I really don't want all my smd pins to
follow this rule, just this pin. I've tried to attach the
Dyn_Thermal_Con_Type = 8_way and/or the Dyn_thermal_Best_Fit = True
properties to the pin, but I still only get 4 connections. Any idea what
else I might try?
        Thanks for the help!
        Jean
