When you placed the walls, you can select the construction method to be by (Right, center or left edge) if you change the walls to center, you will be able to move the grid line and snap it to the center of the wall.
if you have the grid line in place and want a wall centered in it, just select CENTER as the construction method before starting to draw the wall.
Hope this helps
