However, i am now having trouble because some PTH pads look as if they are connected to internal layer copper planes and they are not.....its strange because in other parts of the board, PTHs that go through copper planes but are not connected to them, have a gap round them so you can see that they are not connected to the copper plane.....so why in other areas of the board do they look connected (ie no gap)?
Also, i do not seem to have a component search facility...or highlight component. Do you know how to do this...eg "Find R2"?
Also, there doesnt seem to be a way of "un-showing all layers at once". Do you know how to do this?
