Edit surfaces

Edit surfaces with control points and by changing the surface structure.

Turn surface control points on

PointsOn

Display curve and surface control points.

Insert or remove control points

InsertControlPoint

Add control points to a curve or a row of control points to a surface.

InsertKnot

Add knots to curves or surfaces.

Change control point structure

ChangeDegree

Change the degree of the polynomial that defines the curve or surface by adding or subtracting control points between knot spans, while maintaining the knot structure.

CreaseSplitting

Control whether surface creation commands divide creased surfaces into polysurfaces.

FitSrf

Reduce the number of surface control points.

MakeNonPeriodic

Insert a kink at the start/end of a curve or surface.

MakePeriodic

Remove the kink from the start/end of a curve or surface.

Rebuild

Reconstruct curves, surfaces, and extrusion objects to a specified degree and control point number.

RebuildEdges

Restore surface edges to their surface.

RebuildUV

Reconstructs selected surfaces to degree 3, with a specified control point number, in either the u or v direction.

ShrinkTrimmedSrf

Contract the underlying untrimmed surface close to trimming boundaries.

ShrinkTrimmedSrfToEdge

Contract the underlying untrimmed surface as close as possible to the trimming boundaries.

Smooth

Average the positions of curve and surface control points and mesh vertices and evens out the spacing to remove unwanted detail and loops.

SrfSeam

Change the location where the start and end edges meet on a closed surface.

Weight

Edit the weight of a curve or surface control point.

Change the surface

EndBulge

Adjust the shape of a curve at its end or a surface near an untrimmed edge.

FlattenSrf

Project surface edges onto the construction plane to create planar curves.

SoftEditSrf

Move the surrounding surface area smoothly relative to the distance.

Smash

Flatten a surface without restriction to single-directional curvature.

Join

Connect curves, surface edges, or surfaces to form a single object.

JoinEdge

Join two naked edges that are out of tolerance.

MatchSrf

Adjust a surface edge to have continuity with another surface edge.

MergeAllEdges

Merge all possible edges of a surface or polysurface.

MergeEdge

Combine adjacent edges of the same surface.

MergeSrf

Combine two surfaces at untrimmed edges.
