Hello all,
I'm currently working on a model with a lot of lathe and prism objects, 
and I'm using bezier_spline for the outlines because it's much easier to 
get the shape right (and I'm familiar with how they work). My question 
is that I have a bent strip of plastic (a handle actually) that I have 
modeled with a prism, only because there is no method for sweeping an 
oval or other shape along a spline (which would be ideal). With this 
method, it has sharp edges all along the sides, and I'd like to add a 
sphere_sweep along both sides to round it out. Is there any way for me 
to add a sphere_sweep with the same path data (bezier), or would I need 
to redo the whole thing with a cubic?

On a related note, the b_spline in the sphere_sweep section has no 
documentation besides "b_spline : Approximating the input data using a 
cubic b-spline function, which results in a curved object.", Unlike all 
the other types which have examples in the tutorial section with an 
explanation of how each point is used. More than a sentence about it 
might help.
