Constructor & Destructor Documentation

ON_3dmUnitsAndTolerances() [1/2]

ON_3dmUnitsAndTolerances::ON_3dmUnitsAndTolerances ( )

Scale()

double ON_3dmUnitsAndTolerances::Scale

(

ON::LengthUnitSystem

)

const

Returns scale factor that needs to be applied to change from the argument's unit system to m_unit_system.
When m_unit_system is not ON::LengthUnitSystem::CustomUnits, Scale(us) = ON::UnitScale(us,m_unit_system). When Scale(us) When m_unit_system is ON::LengthUnitSystem::CustomUnits, Scale(us) = ON::UnitScale(us,ON::LengthUnitSystem::Meters)*m_custom_unit_scale.

SetInvalidTolerancesToDefaultValues()

unsigned int ON_3dmUnitsAndTolerances::SetInvalidTolerancesToDefaultValues

(

)

Description: If m_absolute_tolerance is not set to a valid value, it is set to ON_3dmUnitsAndTolerances::DefaultValue.m_absolute_tolerance. If m_angle_tolerance is not set to a valid value, it is set to ON_3dmUnitsAndTolerances::DefaultValue.m_angle_tolerance. If m_relative_tolerance is not set to a valid value, it is set to ON_3dmUnitsAndTolerances::DefaultValue.m_relative_tolerance. Returns: 0: all tolerances were valid 0 != (rc & 1): m_absolute_tolerance was invalid and set to the default value 0 != (rc & 2): m_angle_tolerance was invalid and set to the default value 0 != (rc & 4): m_relative_tolerance was invalid and set to the default value

TolerancesAreValid()

bool ON_3dmUnitsAndTolerances::TolerancesAreValid

(

)

const

Returns: True if tolerances (m_absolute_tolerance, m_angle_tolerance, m_relative_tolerance) are set to valid values.
