Composite Curve: Options Results

The following picking options are available:

Chain: After picking the first and second curve, the most logical path within the direction constraint is selected.
One by One: Individual curves are picked.
Along Open Edges: The path of the composite curve is along open edges.
Faces Outer Boundary: The outer boundary of the picked faces forms the composite curve.
One by One Projected: This option only appears in an NC document and enables you to create a 2D composite curve using curves which do not lie on the same plane.

For each of these options, the following parameters are available:

Tol	Specify the required tolerance.
Composite	Create a composite curve.
Spline	Approximate the composite curve into Nurbs splines.
Fair Spline / Do Not Fair	Decide whether or not to fair the spline.
Approximate to Planar/Don't Approximate	If the composite curve is not planar due to stitch operations or minor changes to the curves, the toggle option Approximate to Planar/Don't Approximate allows you to set the composite curve on the plane thus allowing you to perform operations that require 2D input. This option does not appear in the options One by One Projected.

In the following example, a combination of picking options is used to select the top outer edge of the geometry:

Required Step 1

Using the Chain option, pick the First curve and Last curve. A composite curve is plotted along the most logical course.

If the path progresses as required, pick again a "Last Curve" to complete the composite curve.

If you need to create a composite curve on half of the top outer edge of the geometry you can pick the First Curve and Last Curve adjacent to each other as the composite curve required is the logical path from the First Curve to the Last Curve:

Toggle to the Spline option if you wish to create a single spline along the edges:

If you use the Along Open Edges option, picking the same First Curve and Last Curve will plot the composite curve and include open edges:

If you need to plot a path with individual curves to form the composite curve, use the One by One option combined with the Chain option. The Open/Close toggle parameter lets you close the composite curve automatically or leave it open:

Use the Faces Outer Boundary to plot the curve along the outer boundary of the geometry. In this example the box selection is used to select the whole geometry:

In the following example, a series of faces are picked: The composite curve formed along the outer boundary of the picked faces:

The composite curve formed along the outer boundary of the picked faces:
