I’m trying to make an egg shaped thing with NURBS. 
So far, I’ve beveled and tapered a NURBS circle along a bezier curve to get the general shape. However, with this approach, I’m left with two sharp points at either end of the egg. How do I get rid of these?
You can see the points in the picture:
id try to redo the model by using a cube, subdividing it a few times and using to sphere (shift+alt+s) to make the basic shape, then you wont have those end points
I want to learn how to do it using NURBS
is it not possible to do this using NURBS?
