A new method based on large surface fitting and topology recovery techniques was proposed to deal with the problem of N-sided regions filling in reverse engineering,which appears occasionally in the reconstruction of complex CAD models.Curves were constructed on the surrounding surfaces of the N-sided region,and subsequently the surrounding surfaces were trimmed to obtain a large quadrilateral region which including the N-sided region.Then,all the surrounding surfaces were evenly sampled and a B-spline surface was constructed,by interpolating the discrete boundary constraints and approximating all the points in the quadrilateral region.Finally,the B-spline surface was trimmed and all the surrounding surfaces were refitted subjected to the constraints of points sampled from the B-spline surface.The final model is approximate G1 continuous in global sense,and it keeps the same topology as the original model.
