NURBS1RailSweepSurface ??


I've been searching all day and I cannot figure out how to create a NURBS1RailSweepSurface from scratch - only using MaxScript!

I find the NURBS functionality in maxscript hopelessly confusing, but someone (i believe on this forum) demo'd a reasonable way to create a NURBS curve, which was useful... but apparently not enough!

If anyone knows of any resources or has a good idea on how to do this (or an alternate way using splines??) I'd be really impressed/grateful!
