Structure

The feature structure allows to store information with various levels of complexity.

The hierarchy structures the data from a simple double/integer storage to a CAD feature information. It contains different types of sub-features grouped under feature parameters, depending of its family type. The family type (m_eFamily) specifies the way to interpret the type (m_uiType) as an enumeration value.

The following table shows the correspondence between the family type and the associated enum; and the expected data structure defined below.

Feature type

Family | Corresponding enum | Description

• Information | |

• Type | A3DEFRMEnumDataType | Store a value of an enumeration (CAD type, depth type, …)

• Double Data, Integer Data, String Data | A3DEFRMDoubleDataType,

  A3DEFRMIntegerDataType, A3DEFRMStringDataType | Type of double data (unit, offset, diameter, …)

• Value | A3DEFRMValueType | Type of complex feature (Vector, Depth, …)

• Definition | A3DEFRMDefinitionType | Type of complex feature (Vector, Depth, …)

• Definition Hole, Definition Pattern | A3DEFRMDefinitionHoleType,

  A3DEFRMDefinitionPatternType | Type of complex feature defining a hole (counter sunk, counter bore, …) or pattern

• Feature Definition | A3DEFRMFeatureDefinitionType | Store an information specific to a CAD feature (hole, pattern, extrusion, definition)

• Root | A3DEFRMRoot | Corresponds to the CAD node
