Builds a cross-section from polygons given as 2D points, fusing overlapping ones so the result has no crossings.
fillRule decides which regions count as inside where polygons overlap or a polygon crosses
itself.
The polygons as 2D point lists and the fill rule
The cross-section
Creates a square cross-section of the given side; with center true it is centered on the
origin, otherwise its corner sits there.
The square cross-section
Creates a circular cross-section of the given radius, centered on the origin and drawn with
circularSegments straight sides.
The circle cross-section
Creates a rectangular cross-section with length along X and height along Y; with center
true it is centered on the origin, otherwise its corner sits there.
The length, the height and whether to center it
The rectangle cross-section
Building Manifold cross-sections, the flat outlines that become solids: squares, rectangles, circles and outlines from raw polygons. They lie in the XY plane;
centerplaces a shape on the origin, otherwise its corner sits there.
