Edit surfaces with control points and by changing the surface structure.
Display curve and surface control points.
Add control points to a curve or a row of control points to a surface.
Add knots to curves or surfaces.
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.
Control whether surface creation commands divide creased surfaces into polysurfaces.
Reduce the number of surface control points.
Insert a kink at the start/end of a curve or surface.
Remove the kink from the start/end of a curve or surface.
Reconstruct curves, surfaces, and extrusion objects to a specified degree and control point number.
Restore surface edges to their surface.
Reconstruct surfaces to a specified control point number in the u or v directions.
Contract the underlying untrimmed surface close to trimming boundaries.
Contract the underlying untrimmed surface as close as possible to the trimming boundaries.
Average the positions of curve and surface control points and mesh vertices and evens out the spacing to remove unwanted detail and loops.
Change the location where the start and end edges meet on a closed surface.
Edit the weight of a curve or surface control point.
Adjust the shape of a curve at its end or a surface near an untrimmed edge.
Project surface edges onto the construction plane to create planar curves.
Move the surrounding surface area smoothly relative to the distance.
Flatten a surface without restriction to single-directional curvature.
Connect curves, surface edges, or surfaces to form a single object.
Join two naked edges that are out of tolerance.
Adjust a surface edge to have continuity with another surface edge.
Merge all possible edges of a surface or polysurface.
Combine adjacent edges of the same surface.
Combine two surfaces at untrimmed edges.
