One Curve

Curve Info
Print splines, segments and empty splines information to the Info header and Info editor.
Calc Length
Calculate the length of the curve and show in the add-on’s panel.
Curve Splines Info
Print splines information to the Info header and Info editor.
Curve Segments Info
Print segments information to the Info header and Info editor.
Set origin to spline start
Move the origin of the curve to the first point.

Curve

Intersect curves
Create an intersection between flat curves on the same plane.

Two Curves Loft

Loft
Loft a mesh object between two Bézier curves.
Auto Loft
Turn on to store the loft data if you move or edit the curves.
Update Auto Loft
Press this button to update the new loft mesh position after moving or editing parent curves.

Advanced

Curve Outline
Create an outline around a selected curve object.
Separate Outline or Selected
Separate the Outline mesh from the original.
Fillet
Round or chamfer Bézier point fillets.
Handle Projection
To do.
Divide
Subdivide selection or filleted corners.
Scale Reset
Reset the objects scale to (1, 1, 1).
Birail
It creates a surface from a profile and two paths. The order in which you select the curves and its direction is important to make this work right.
Convert Selected Faces to Bézier
Select faces and convert them to Bézier curves.
Convert Bézier to Surface
Convert the selected curve to a NURBS surface.
