i read step using XCAF.
=============================================
code:
STEPCAFControl_Reader sReader;
...
...
...
IFSelect_ReturnStatus status = sReader.ReadFile((CStringA)pathSTEP);
sReader.Transfer(m_DataDoc); <-------ERROR
...

...
=============================================

callstack:
Standard_Boolean Standard_Transient::IsKind (const Handle(Standard_Type)& aType) const
{
return DynamicType()->SubType ( aType );
}

in Standard_Transient::IsKind function, Message is "this is nullptr."

because, when translating face, can not make wire from face.

but, CAD Assistant can read this step file .

how solve this problem??

Register a bug on Bugtracker.
Provide sample file reproducing the problem.
Suggest a patch for OCCT, if possible.

- I'm sorry. I can't provide sample that reproducing the problem.
- I have tested that Other OCC projects can read this file.
- FreeCAD: Fail (abnormal termination)
- MAYO: Fail (abnormal termination)
- SALOME: Success
- NIST - STEP File Analyzer and Viewer: Success
- I compared the step import code of SALOME and NIST with my code, but there is no difference.

If you are not able to share file sample, you may debug issue in OCCT source code and suggest bugfix adding missing NULL checks.

We have the exact same crash in our application.
I have create an issue in Mantis https://tracker.dev.opencascade.org/view.php?id=32980

I read the issue you posted. The STEP where the problem occurred is also a file created by SolidWorks.
