There has to be a better way than the system I’ve dreamt up and have been using for a while;
When I need a 3D curve, I’ll draw two curves in different planes, extrude and intersect them. Problem is, the result isn’t a Bezier, but a succession of semi-randomly connected segments. This is of course due to a lack of synchronicity in the spacing of the vertices in the original (blue in the screen shot) curves.
How should I go about drawing a precise 3D Bezier directly, in order to obtain a mathematically correct curve?
