◆ LinkedInstanceDefinitionSerialNumber()

unsigned int CRhinoTextureMapping::LinkedInstanceDefinitionSerialNumber ( ) const

Returns: 0: The linetype is not part of a linked instance definition 1-1000: These numbers are reserved for future use. >1000: CRhinoDoc::m_instance_defintion_table.FindBySerialNumber() can be used to find the instance definition. Remarks: The linked instance definition serial number is a runtime value. It is not saved in files and it is generally different the next time a file is read.

◆ UseCount()

unsigned int CRhinoTextureMapping::UseCount ( ) const

Returns: Number of object using this mapping.

◆ WorksessionReferenceModelSerialNumber()

unsigned int CRhinoTextureMapping::WorksessionReferenceModelSerialNumber ( ) const

Returns: Worksession reference model id. 0: linetype is not in a reference model. 1: linetype is in an unidentified worksession reference model. 2-1000: reserved for future use >1000: Serial number of the worksession reference model.
Remarks: The reference model serial number is a runtime value. It is not saved in files and it is generally different the next time a file is read.
