Delete/Remove entities from step model.

Hello,

I am trying to delete/remove some of the entities in my STEP model before proceeding to write STEP file. I want to delete the StepGeom_Axis2Placement3d entities whose name is empty. Here is my code:

Handle(StepData_StepModel) aWriteModel = Handle(StepData_StepModel)::DownCast(writer.Writer().WS()->Model());
for (int i = 1; i <= aWriteModel->NbEntities(); i++)
{
const Handle(Standard_Transient)& anEnt = aReadModel->Value(i);
if (!anEnt->IsKind(STANDARD_TYPE(StepGeom_Axis2Placement3d)))
{
continue;
}
Handle(StepGeom_Axis2Placement3d) stpEnt = Handle(StepGeom_Axis2Placement3d)::DownCast(anEnt);
auto name = stpEnt->Name();
if (name->IsEmpty()) {
//delete this stpEnt object.
}
}
//write step

Is there any way to do it?

Best Regards,
Prajwal.
