Detailed Description
Creates and accesses a hierarchy of descriptive names and modeller data that can be applied to any PRC entity.
Entity type is kA3DTypeRootBase
This module lets you create a hierarchy of descriptive names and modeller data (called root-level attributes) that can be applied to any PRC entity. These attributes are packaged as an A3DRootBase entity that is referenced from the PRC entity they describe.
The following sample code shows how to create root-level attributes for any PRC entity. In this case, the attributes include modeller data. For restrictions on specifying modeller data, see A3DMiscAttributeData.
The following illustration shows the result of the sample code.
The sample code creates an A3DRootBase entity that houses three A3DMiscAttribute entities, each of which reference an A3DMiscSingleAttributeData structure. Each A3DMiscSingleAttributeData structure provides modeller data of type kA3DModellerAttributeTypeString.

Function Documentation
A3DStatus A3DRootBaseGet | ( | const A3DRootBase * | pRootBase, |
A3DRootBaseData * | pData | ||
) |
Populates an A3DRootBaseData structure with the data from a PRC entity.
- Version
- 2.0
A3DStatus A3DRootBaseSet | ( | A3DRootBase * | pRootBase, |
const A3DRootBaseData * | pData | ||
) |
Adds an A3DRootBaseData structure to an existing PRC entity.
- Version
- 2.0
- Note
- A3DRootBase is an abstract class and cannot be directly created; however, any entity created with a function of the form
A3DEntity_nameCreate
results in the creation of a PRC entity of typeA3DRootBase
and of typeA3DEntity_name
.
