Utils

Add information for default value returned on following methods - older versions are deprecated
Dtk_ErrorStatus Dtk_Component::GetConceptionUnitScale(Dtk_Double64 &OutUnitScale)const
Dtk_ErrorStatus Dtk_Body::GetTolerance(Dtk_Double64 &outTolerance)
Dtk_ErrorStatus Dtk_Edge::GetTolerance(Dtk_Double64 &outTolerance)
Dtk_ErrorStatus Dtk_Vertex::GetTolerance(Dtk_Double64 &outTolerance)
All these methods return dtkWarningDefaultValue or dtkNoError
Remove useless methods
Dtk_Double64 Dtk_Body::GetTolerance()
void Dtk_Body::SetTolerance(Dtk_Double64 inTolerance)
Dtk_TopologicalEntity::GetTolerance()
Discretisation of curve
Now you can choice the discretisation value ( linear method ) for the curve ( wireframe entities into a Dtk_BodyPtr )
Previously this value was 0.01 , it remain of default value , but you can change this value with the function tess_set_Wireframe_Discretisation(double tol)
You can get the value used with the function double tess_get_Wireframe_Discretisation()
These method are defined in tess.h
