Thanks for your reply. Then i had go to options---> stack up settings, how can i insert the define the layer by layer and how to give the drill size of it.
(For e.g):- For Double layer, In case i am using via 1 means drill size will be 0.60. So after that i am using 4 layer board means i use th via 2 means how can i insert it and provide the drill size.
Can u provide me an better tutorial link for the 4 layer board design. In my concern they use to use 4 layer board, me was searching the better tuto for the 4 layer design.
