<p>A method of digitising a three dimensional object 10. The method using a point digitiser which defines the envelope dimensions 11, 12, 13, 14, 15 and 16 of the object 10 and uses a cloud data capture technique to acquire data points as a pen-element of the digitiser is scrubbed or randomly moved across the object 10 surface. The data points being processed by the digitiser to produce a plurality of object contours between opposed edges of the envelope dimension 13, 14, 15, 16 at spaced points Sj, Ej respectively. These object contours defining the object 10 shape for digital mapping within a computer aided design (CAD) system. <IMAGE></p> |
