Editing Curves

	CurvesKeypoint Curve ToolboxDrag Keypoints [Rhino: no equivalent] Allows you to move keypoints on keypoint curves.
	Curve EditModifyTransform Curve [Rhino: no equivalent] Provides a direct way of positioning a curve so that it intersects two rail curves by conserving its original shape.
	Curve EditModifyStretch [Rhino: no equivalent] Lets you stretch or reshape a curve by moving handles attached to the curve.
	Curve EditModifyAdd Points [Rhino: no equivalent] Lets you add control points to the end of an existing curve, as if you were still drawing it using the new curve tools.
	Curve EditRebuild Curve [Rhino: Rebuild, RebuildCrvNonUniform, MakeUniform, SimplifyCrv, Fair, Smooth, FitCrv and ChangeDegree] Recreates a curve with the same shape but different mathematical properties.
	Curve EditProject Tangent [Rhino: Match] Allows for the modification of a curve or surface edge to achieve tangency or curvature continuity with a surface, or tangency with a curve intersection. [The Align tool provides similar functionality.]
	Curve EditCurve Section [Rhino: Delete Subcurve] Cuts, trims, or creates new geometry along a number of curves based on a chosen criterion.
	Object EditAttachAttach [Rhino: Match Curve] Joins curves by connecting their endpoints, joins surfaces by connecting the edges, or closes a surface by connecting its opposite edges. Note: Attaching curves or surfaces with coincident edges can lead to nodes or tension at the intersection, and should be used with care.
	Object EditAttachDetach [Rhino: Subcurve] Separates a curve or surface into two or more objects at any point.
	Object EditInsert [Rhino: no equivalent] Adds an edit point to a curve, or an edit point isoparametric curve to a surface.
	Object EditExtend [Rhino: Extend Curve] Extends a curve or surface beyond its current endpoint or edge by adding new geometry. A precise value can be entered at the prompt line.
	Object EditOffset [Rhino: Offset Curve] Creates a new object offset a specific distance from an original.
	Object EditAlignAlign [Rhino: Match Curve] Aligns the endpoints/edges of curves and/or surfaces, or interior isoparametric curves.
	LocatorsCurve Curvature [Rhino: Curvature Graph] Adds a locator that shows the curvature or radius comb of a curve.
