Abstract:
1. A method of determining a horizontal profile line defined by walls that are essentially vertical, by using a pointer having two calibrated reference points, the method comprising the following successive steps: a) placing the pointer horizontally in contact with a point of the profile line to be determined; b) from a stationary origin point situated substantially in the same horizontal plane as the contact point and the two calibrated reference points of the pointer, successively measuring the length of the segments joining the origin point to each of the reference points, and also measuring the angle between said two segments; c) deducing by calculation the coordinates of the contact point in said horizontal plane, and storing said coordinates; and reiterating steps a), b), c) for a plurality of points on the profile line to be determined, including in said plurality of points at least the angle points situated at the intersections between said essentially vertical walls.
