摘要： A marking system is disclosed that enables a user to lay out a foundation/perimeter for a structure without requiring the use of measuring instruments and/or complex procedures. The system includes six wire-like premeasured members that are releasably attached to specially designed corner members. The system is laid out with four of the wire-like members enclosing a square or rectangular area with their ends attached to the corner members. The remaining two wire-like members diagonally cross the enclosed area and each is attached at its ends to opposite corner members. When the diagonals intersect at their midpoints, the user is assured that the corners form right angles. Each of the diagonally placed members preferably includes a marking band at its midpoint to facilitate the locating of the midpoints by a user.
