Follow the steps:
- take as1-oc-214.stp from www.cax-if.org
- load into an XDE document using STEPCAFControl_Reader
Inspecting (e.g. using TDF_ChildIterator and TDF_AttributeIterator) the data structure shows that there two(!?) 'TDataStd_TreeNode' attributes on some labels (e.g. 0:1:1:3), which would be against the rule stating that only one attribute of each type can reside on a label.
This happens for models having assembly structure.
Using OCC 6.3.0
Is this a bug? Can anyone comment?
