Blend-Curve

See also Add Blend-Curve


A Blend-Curve sketch-element has a start-Point and an end-Point.

You can use the Blend-Curve dialog-box to edit these geometric-properties AT its start-Point and AT its end-Point:

Angle

Curvature

Curvature Rate  

Typically, you will merge the start-Point and/or end-Point of the Blend-Curve with another sketch-elements.

The default geometric-properties ensure geometric continuity of the Blend-Curve with the adjacent sketch-elements.

Case 0 : The Blend-Curve is not merged with another sketch-element. You can edit these geometric-properties at its start-Point and end-Point:

Angle (default = 0)

Curvature (default = 0)

Curvature Rate (default = 0)

Default values

Case 1 : You merge the start-Point and/or end-Point of the Blend-Curve with a Line.

Angle is equal to the angle of the Line

Curvature is equal to zero

Curvature Rate  is equal to zero

Case 2 : Merge the start-Point and/or end-Point of the Blend-Curve with an Arc.

Angle is equal to the tangent of the Arc

Curvature is equal to 1 / Radius of the Arc (m)

Curvature Rate - is equal to zero

Case 3 : Merge the start-Point and/or end-Point of the Blend-Curve with a Blend-Curve.

Edit the end-Point of a Blend-Curve that you merge with the start-Point of an adjacent, or following, Blend-Curve.

In the Blend-Curve dialog-box, edit the:

Angle : Disable the end-Point Angle check-box: edit the Angle - the angle of the adjacent Blend-Curve with equal the angle you enter.

Curvature : Disable the end-Point Curvature check-box: edit the Curvature - the curvature of the adjacent Blend-Curve with equal the curvature you enter.

Curvature-Rate : Disable the end-Point Curvature-Rate check-box: edit the Curvature-Rate - the curvature-rate of the adjacent Blend-Curve with equal the curvature-rate you enter.

You can edit the geometric-properties
