Keypoint Curves Enhancements

The keypoint curve tools have been improved and consolidated into a new toolbox.

Choose Curves > Keypoint curve toolbox to open the following toolbox:

This toolbox contains all the tools used to create and manipulate keypoint curves.

Other enhancements to keypoint curves include:

Ability to create accurate (non-periodic) circles and ellipses with a smaller degree and number of spans.
The keypoint Lines tools now have a degree option. Possible values are 1 to 7.
Options have been renamed to be consistent with other tools (that is Degree instead of Arc Degree and Spans instead of Arc Spans).
For keypoint Arcs tools, the default number of spans is set to 1, and the default degree is set to the minimum value that will provide an arc of constant radius.
The Join curves tool (removed in v13.0) has been added back. You can find it in the Keypoint Curve Toolbox under Break & Join > Join curves.
To join two curves at their endpoints, make sure their endpoints overlap (are coincident), then choose the tool and click on the overlapping keypoint or edit point.
