Adjustable Curve Blend

The BlendCrv command creates a blend curve between curves and / or surface edges with control over the continuity with the input curves.

Select the curves.
Select a control point to adjust.
Press Shift and select for symmetry.
A preview of the curves displays that allows adjustment of the curve before it is made.

Selection options
BlendStart	Specifies where on the curve the blend will start. CurveEnd Starts the blend at the end of the curve where the curve was selected. PickPoint Starts the blend at the location on the curve where the curve was selected.
Edges	Restricts selection to surface edges.
Point	Specifies a point to blend to.
Edit	If the blend was made with history recording on, you can select the blend to re-edit the curve.
SubCrv	Type subcrv to select part of a curve as input.

Keys for control
Continuity Curve	Sets the continuity option between the blend curve and the input curves or edges. Position Tangency Curvature G3 G4
Flip 1 / 2	Reverses the direction of the specified curve.
Trim	Trims the input curves to the resulting curve.
Join	Joins the resulting curves.
Show Curvature	Displays the curvature graph.

Alt	Hold Alt while dragging the handles to change the angle between the shape curve and the surface edge. By default the shape curves are perpendicular to the surface edge.
Shift	Hold Shift to control symmetry. By default the shape curves are separately edited at each end, with symmetry, point editing is mirrored to the other end of the curve.
