To display the Arc context menu, right-click on an arc when the Curve editor tab is displayed.
This menu contains the following:
Modify — Click to select the arc and display the Arc Editor dialog so you can edit the radius or span of the arc.
The curve editor merges segments that join the selected segment (at either end). The curve editor then merges segments that join the resulting new segment. This continues until no more merges are possible. Where there is a choice of curves to merge, the curve with the smallest tangent angle discrepancy is chosen.
Converts this:
to this:
Pattern — Displays the name of the pattern, in this case Input curves.
Segment — Displays the properties of this segment. In this case the ninth segment.
