# 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.

UnrollSrfUV

Flatten (develop) a surface or polysurface with curvature in one direction to a planar surface while maintaining the u- and v-directions of the input surface.
