Hi dipin, studio splines are great way to help you in remastering an iges part. My method is to first of all create a studio spline in one of the datum reference plane(snap to plane by F8) using through points option in two directions(say X &Y) as shown above by sajid. Click ok to confirm the spline. After that, you can edit the spline(double click on it) and select 'by poles' mode. Now you should select a plane perpendicular to previous plane and move the poles only in Z axis. You should not select any other planes for moving the spline points(a point to be constrained in 3 mutually perpendicular axis only). If you move the spline points in more than 3 axes, positions will alter in other planes. Hope this is helpful.
