i ever wanted the bezierhandles of a spline to snap, but in max there is no such function. so i decided to write a little script.
the script basically generates another spline called snapspline. the vertices of the snapspline are following the bezierhandles of the original spline with an eventhandler. so you are able to snap the vertices of the snapspline instead of the handles.
if you are working with the original spline, the script does its job well. but when you select the snapspline and go to subobjectlevel max crashes. i can`t find the reason for this bug.
please take a look at the script
