Thermal Relief doesn't work for Power palnes

Hi,

I have defined circle as Thermal Relief for all layers of my pads. Below are some questions regarding shape drawing in various layaers:

1- Thermal Relief doesn't work for power planes while it works for signal, Top & Bottom Layers. I see that it only uses a zero length cross to connect pad to polygone or shape in power planes (Figure 1)

2- Shape in power planes is connected to pins of other nets!.(Figure 2)

3- After changing constraints shapes or polygones seem to be connected directly to pads!. How can I make sure that all constraints are applied after any shape or constraint edit (Figure 3)

4- Where can I change settings for thermal pads? I mean "connect width" and "gap" between plane and pad (Figure 4)

5- Do I have to use Shape-> Check for all shapes or polygones everytime I make changes in Constraint Manager or there is a much easier way for it?

I am very short of time. So, I need urgent help.

Thanks all in advance,

Hossein
