Curves from Surfaces

By selecting any surface it is possible to obtain the longitudinal, transversal and contouring curves. In case more surfaces exist in the project it is possible to extrapolate their intersection point. Inside the window that appears the operator must select the curves to extrapolate by ticking the relevant box.

As regards the longitudinal and transversal curves, the user must select the point on the surface through which the curves to be extracted pass. Such a selection can occur by using the mouse or via keyboard.

As regards the intersection it is necessary to select the intersections that will have to be extrapolated.

The extrapolated curves are NURBS-type; to transform them into straight lines and arcs please refer to the function Explode in the Edit chapter.
