To my knowledge, in creating a spline, NX would automatically add knots to divide the spline into multiple segments virtually and fulfill: points = degrees + segments
But I can't find some information about how NX controls the continuity at each knot within a spline.
Below are some of my rough ideas:
- A single-segment spline (B-curve) is best for achieving a high-quality surface
- At a knot of a multi-segment spline, the continuity is ≥G1.
- To build a high-quality surface, a multi-segment spline would be much better than a curve string (arcs/conics/splines...) connected with manually specified continuity.
- "Divide-By Bounding Objects" only cuts a spline for handling separately, without affecting the basic mathematics.
Are they correct? Hope to have your suggestions. Thank you!
