CLIP is a computer software application for the design, evaluation and execution of work control and construction of three-dimensional linear works. CLIP has an outstanding potency of calculation based on linear works expert logic that, together with its user-friendly facilities, makes it a highly appreciated tool for Official Institutions, control and supervision companies, designers and constructors in all the countries where it is used. Allow the design over cartography of large volumes of information, with a surprising treatment speed, which makes CLIP one of the fastest applications in the marketplace. Its thoroughly researched interface offers a better analysis of the model, allowing, for example, synchronized windows opening, according to the user criterion, of axes, stretches, transversal profile, land movements and realistic 3D viewings in the same screen. These elements are automatically updated after every change in the design
