I am trying to figure out why bezier curve is better than multi span curve or surface…From my understanding A class curve/surface is smoother but I did a little experiment.
I build a curve with 6cps and degree 5 and then used fitcrv which produced 11cps, degree 3 and 9 knots. I run crvdeviation and it came up with 0.000239…cm. So how is it smoother? It’s almost identical
Then I made a surface from both curves to check reflections/continuity and again it looks identical.
The only difference is in curvature graph. The breaks between knots are visible at the ends but why does it even matter if the surface appear to be the same when analyzing it with zebra and emap?
Finally I moved one of the points up by 0.5cm which resulted in even bigger break in curvature graph of 8 span surface while A class srf graph remained smooth
Now the changes are visible in reflection of surface and they don’t appear to be as smooth anymore.
So to conclude, correct me if I am wrong but A class surface is easier for editing while maintaining the smoothness but if we create multi span surface and don’t move its control points it looks equally smooth so why is it bad idea to be using them? Why is it not prefered option for A class modeling?
