Curve > Control Point Curve
Main2 > Control Point Curve
Curve > Free-Form > Control Points
Draws a curve from control point locations.
Steps:
Pick the start of the curve.
Pick the next points.
Press Enter to end the curve.
Note: The Curve command makes a curve of degree <number of points> -1 as long as the number of control points is less than or equal to the degree setting.

Curve > Control Point Curve Main2 > Control Point Curve
Curve > Free-Form > Control Points |
Draws a curve through selected locations in space.
Note: Many CAD programs use the term spline to describe an interpolated curve.
Steps:
Options
StartTangent
Draws the start of curve tangent to another curve.
EndTangent
Draws the end of the curve tangent to another curve.

Draws a curve through selected locations on a surface.
Steps:
Notes
The curve will not cross seams in the surface.
Object snaps End, Cen, Mid, Near, Knot, and Int can be used.

Draws illustration-program-style chained Bézier curves.
Steps:
Pick the first curve point.
Pick a handle location.
Repeat the steps to place additional points, and press Enter to end the command.
Options
Alt key
Press the Alt key to place a kink.
Ctrl key

Draws a curve by dragging the mouse.
Steps (click and drag):
Click, hold, and drag the left mouse button to sketch.
Release the mouse button to end the curve.
Note: Drawing a single curve in multiple viewports is not allowed using this method.
Steps (click and release, click to end):
Click and release the left mouse button, and move the mouse.
Click and release the mouse button.
Note: Drawing a single curve in multiple viewports is allowed using this method.
Options
Closed
Creates a closed curve. Select the option before dragging points with the mouse. The curve closes when you stop dragging points.
Planar
Creates a planar curve.
OnSurface
Sketches a curve on a surface.
OnMesh
Sketches a curve on a polygon mesh.
