On elevations views I cant activate both bubbles into grid lines...only one appears (superior side)...both buttons "Bubble at End Default" are activated on "Type Properties" of the System Family: Grid. On level 1, only horizontal grid lines are visible...I wonder what appends with vertical grid lines. I can see both grid lines (horizontal and vertical) on Site view... Any help will be appreciate... I just upgrade to new 7 build. Daniel
