fixTolerance(value, ShapeType=Shape)
Sets (enforces) tolerances in a shape to the given value
ShapeType = Vertex : only vertices are set
ShapeType = Edge : only edges are set
ShapeType = Face : only faces are set
ShapeType = Wire : to have edges and their vertices set
ShapeType = other value : all (vertices,edges,faces) are set

limitTolerance(tmin, tmax=0, ShapeType=Shape)
Limits tolerances in a shape as follows :
tmin = tmax -> as fixTolerance (forces)
tmin = 0 -> maximum tolerance will be tmax
tmax = 0 or not given (more generally, tmax &lt; tmin) ->
tmax ignored, minimum will be tmin
else, maximum will be max and minimum will be min
ShapeType = Vertex : only vertices are set
ShapeType = Edge : only edges are set
ShapeType = Face : only faces are set
ShapeType = Wire : to have edges and their vertices set
ShapeType = other value : all (vertices,edges,faces) are set
Returns True if at least one tolerance of the sub-shape has
been modified
