We extract from the clouds of plants points, sections, axonometric splits, three-dimensional views, discontinuity lines and virtual tours. We monitor the works carried out and the movements / changes in progress using the data collected and reference systems. The "point cloud" datum is particularly useful also in order to determine with great precision splits, cracks and degradations in general of buildings subject to restoration.We process parametric surfaces obtaining information on the geometries detected at the customer's request.
