 		 #108155 - Placing Vias
Responding to: ???'s previous message
Hello every one,
Iam using ORCad - 'Layout plus' software for PCB design.
Can any one tell me how to place vias in a two layer PCB.
I have a PC Add on card PCB design.
I need to place Vias in it to connect the ground fills at the top layer to the solid ground plane in the bottom layer.
If i palce the via after doing copper pour i am getting ' pour spacing error'.
If i do copper pour after placing the Vias, it does not make the vias to stitch the top copper fills with bottom ground plane but gets isolated from the copper fills.

Can any one suggest me asuitable way to do this.

Thanking you,
-suresh.
