We've implemented G6.2 NURBS 3D interpolation in our github branch.
Here's the detail description:
G6.2 (NURBS Format)
Format:
G62 P_K_X_Y_Z_A_B_C_U_V_W_R_F_I_D_;
Descriptions:
G6.2: Recognized by interpreter for NURBS interpolation
P: Curve order
X, Y, Z, A, B, C, U, V, W: A set of NURBS control point
(x,y,z,a,b,c,u,v,w)
R: Weighting number for each set of control point
K: One element of Knot vector
F: Feedrate
I: curve Length
D: curvature
It's also available at:

You may get a screenshot for the NURBS_3D there.
As our NURBS project died for more than 18 months, the code is no longer
maintained since then. I just fixed it a bit to simulate it and take
screenshot. It's in our "beagle" branch.
