scad-utils for OpenSCAD

The Morphology module provides functions to manipulate 2D shapes through offsets, rounding, and shelling. These functions are designed to be used as wrappers around 2D shapes (like polygon).

Available Functions:

• inset(d=1): Creates a polygon at an offset d inside a 2D shape.
• outset(d=1): Creates a polygon at an offset d outside a 2D shape.
• fillet(r=1): Adds fillets of radius r to all concave corners of a 2D shape.
• rounding(r=1): Adds rounding to all convex corners of a 2D shape.
• shell(d, center=false): Creates a shell of width d along the edge of a 2D shape.
  • Positive d: Shell is placed on the outside.
  • Negative d: Shell is placed on the inside.
  • center=true and positive d: Shell is centered on the edge.

module shape() {
    polygon([[0,0],[1,0],[1.5,1],[2.5,1],[2,-1],[0,-1]]);
}

// Examples of usage:
inset(d=0.3) shape();
outset(d=0.3) shape();
rounding(r=0.3) shape();
fillet(r=0.3) shape();
shell(d=0.3) shape();
shell(d=-0.3) shape();
shell(d=0.3, center=true) shape();
