Group/Ungroup Curves

  The Group/Ungroup Curves option allows you to group curves into a composite curve, or ungroup composite curves into separate curves. This is needed for associating an edge to a set of curves. The curves should first be grouped into a composite curve, and then the edge can be associated to that composite curve.

Composite curves can be displayed by right-clicking on Curves in the Display Tree and selecting the option Show Composite.

Group Curves

groups the selected curves into one composite curve. The selected curves can include existing composite curves.

Selected

groups only the selected curves.

All tangential

groups all curves that are tangential to the selected curves.

You can use the default value of 10 degrees, or set a value for Tangential angle tolerance.

Part by Part

groups all the curves in each part into composite curves.

Ungroup Curves

allows you to select the composite curve to ungroup.
