Object Edit > Attach > Attach Joins curves by connecting their endpoints, joins surfaces by connecting the edges, or closes a surface by connecting its opposite edges.
Object Edit > Insert Adds an edit point to a curve, or an isoparametric curve or curve-on-surface to a surface.
Object Edit > Extend Extends a curve or surface beyond its current endpoint or edge by adding new geometry.
Object Edit > Symmetric Modeling Makes the selected geometry symmetric, and lets you modify the controls (CVs, edit points, blend points) on one side, while the corresponding controls on the symmetric half update automatically to maintain the symmetry.
Object Edit > Align > Align Aligns a curve or surface edge to another curve, or surface edge. Also aligns an edge to the interior of a surface.
Object Edit > Offset Creates an object offset a specific distance from an original.
Object Edit > Dynamic Shape Modeling > Transformer Rig The Transformer Rig sets up construction history; the actual modification of the model happens “outside” of the shape modeling tool, and is performed by moving and modifying CVs of the modifiers.
Object Edit > Dynamic Shape Modeling > Conform Rig Enables you to perform modeling operations that are similar to “badging,” or deforming an otherwise flat feature onto a curved surface so that the output conforms to the shape of the curved surface.
Object Edit > Object Editor Allows you to reshape curves and surfaces by dragging handles attached to the object.
Object Edit > Close Converts an open curve or surface to closed, or a closed curve or surface to open.
Object Edit > Smooth Improves the smoothness of surfaces and curves by harmonizing CV distances and simultaneously minimizing angles/kinks inside the hulls.
