Preserve Groups
If this option is enabled, the elements are disconnected from the object in one piece (provided they
were connected to begin with). If the option is disabled, the elements are separated from one other
as well as from the object.
Edge To Spline
This command creates a spline from an edge selection.
A spline (right) is created from the selected edges (left).
Line Up
For best results, use a Linear or Bezier spline.
Before. After.
This command aligns sequentially selected points to a straight line. The points are aligned between
the two outer points of the selection (on the basis of the spline point order). If no points are selected,
the entire spline is aligned.
Project
The accuracy of the projected spline depends on two factors: how nely the spline is subdivided (the
Project function does not add new points) and the alignment of the splines to the surface. For best
results, use a Bezier spline.
