CloseEdgeLoop(List<Edge>, Boolean)

Takes a (closed) loop of edges of this shell as parameter sortedEdges and tries to create a shell, which connects the edges. It heals the hole, described by sortedEdges. The edges are sorted so that following the edges they go clockwise around the hole to fix.

Declaration

Parameters
Type Name Description
System.Collections.Generic.List<Edge> sortedEdges

Edges, which only have the PrimaryFace set (the SecondaryFace must be null)

FeatureFromEdges(Edge[], Face[])

edgeLoop must be a closed set of edges on this shell. The shell will be splitted at this loop. All edges in edgeLoop join one of the faces in facesToCutoff. These parts of the shell will not be used. At this loop, which remains open in the first step, the resulting shell will be closed by faces with surfaces from facesToCutOff.

Declaration
public Shell FeatureFromEdges(Edge[] edgeLoop, Face[] facesToCutOff)
Parameters
Type Name Description
Edge[] edgeLoop
Face[] facesToCutOff
Returns
Type Description
Shell

FeatureFromFace(Face)

Tries to find a feature like a drill hole or a part sticking out of the shell starting with this face. The rule is that faces connected with the face toStartWith are combined until the open edges have the same underlying surface. There might be one or two loops of such open edges (two loops for a hole going through the body).

Declaration
public Shell FeatureFromFace(Face toStartWith)
Parameters
Type Name Description
Face toStartWith
Returns
Type Description
Shell
