3、O 10303-104:2000 was prepared by Technical Committee ISO/TC 184, Automation systems and integration, Subcommittee SC 4, Industrial data. The purpose of the modifications to the text of ISO 10303-104:2000 is to correct a scoping issue in the FUNCTION required jd_nodes and the FUNCTION required_3d_nod

4、es. In addition, the FUNCTION variable_value_type is corrected to return the correct value for a surface _tensor2 _ 2d _variable. ICS 25.040.40 Ref.
