edgestowires()

def OpenSCAD2Dgeom.edgestowires	(		edgelist,
			eps = 0.001
	)

takes list of edges and returns a list of wires

endpointdistance()

def OpenSCAD2Dgeom.endpointdistance

(

edges

)

return the distance of vertices in path (list of edges) as
maximum, minimum and distance between start and endpoint
it expects the edges to be traversed forward starting from Vertex 0

endpointdistancedebuglist()

def OpenSCAD2Dgeom.endpointdistancedebuglist

(

debuglist

)

return the distance of vertices in path (list of edges) as
maximum, minimum and distance between start and endpoint
it expects a 'not reversed' flag for every edge

findConnectedEdges()

def OpenSCAD2Dgeom.findConnectedEdges	(		edgelist,
			eps = 1e-6,
			debug = False
	)

returns a list of list of connected edges

importDXFface()

def OpenSCAD2Dgeom.importDXFface	(		filename,

			doc = None
	)

subtractfaces()

def OpenSCAD2Dgeom.subtractfaces

(

faces

)

searches for the biggest face and subtracts all smaller ones from the
first. Only makes sense if all faces overlap.

subtractfaces2()

def OpenSCAD2Dgeom.subtractfaces2

(

faces

)

Sort faces, check if they overlap. Subtract overlapping face and fuse
nonoverlapping groups.

superWireReverse()

def OpenSCAD2Dgeom.superWireReverse	(		debuglist,
			closed = False
	)

superWireReverse(debuglist,[closed]): forces a wire between edges
that don't necessarily have coincident endpoints. If closed=True, wire
will always be closed. debuglist has a tuple for every edge.The first
entry is the edge, the second is the flag 'does not need to be inverted'
