Flatten curves and surfaces
Flatten a portion of a curve.
Flatten surfaces for pattern-making and flat-fabrication of curved surfaces.
Flatten curves

InsertLineIntoCrv
Flatten the curve segment between picked points.
Flatten surfaces

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

Smash
Flatten a surface without restriction to single-directional curvature.

Squish
Flatten a non-developable (curved in two directions) 3-D mesh or NURBS surface into a flat 2-D pattern.

SquishBack
Return curves and surfaces to the original squished 3-D shape.

UnrollSrf
Flatten (develop) a surface or polysurface with curvature in one direction to a planar surface.
