<UserDocu>
getTolerance(mode, ShapeType=Shape) -> float
Determines a tolerance from the ones stored in a shape
mode = 0 : returns the average value between sub-shapes,
mode &gt; 0 : returns the maximal found,
mode &lt; 0 : returns the minimal found.
ShapeType defines what kinds of sub-shapes to consider:
Shape (default) : all : Vertex, Edge, Face,
Vertex : only vertices,
Edge : only edges,
Face : only faces,
Shell : combined Shell + Face, for each face (and containing
shell), also checks edge and Vertex

overTolerance(value, ShapeType=Shape) -> float
