Get names from STEP file.

Hi guys,

I have a STEP file which contains two solid shapes. One is named as "test", another named as "Boss-Extrude1". In SolidWorks2010, it can read all solid shapes' name. But in my OCC6.5.3, I can only read the compound shape "Assemb1" and compound shape "Part1".
The hierarchy of the step file seems:
Compound(Assemb1) -> Compound(Part1) --> Solid 1 and Solid 2. No matter how I try, I can't get two solids names. I am using STEPCAFControl_Reader.

Any suggestion is welcome. Thanks.

I have the same question.

use STEPCAFControl_Reader to Transfer Handle(TDocStd_Document).
then (XCAFDoc_ShapeTool) myAssembly = XCAFDoc_DocumentTool::ShapeTool(doc->Main());
and get a label from labels, use aLabel.FindAttribute(TDataStd_Name::GetID(), N) to get name.

Hi WuXuan,

Have you tried my attached .step file? Does it work for you?

Dear Ding,
Indeed the document structure doesn't contain names of the mentioned solids.
Probably it may be a bug.
