Abstract
The invention provides 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 on the profile line to be determined; b) from an origin point, measuring in succession the lengths of segments joining the origin point to each reference point, and also the angle between the two segments; c) deducing by calculation the coordinates of the contact point in the associated 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 at least the angle points situated at the intersections between said essentially vertical walls. The invention also provides apparatus for implementing the above method.
