Get dimensions data for STEP(AP242)

Hi Team, I have created a dimension in creoand exported a step file using AP 242 protocol.
I am trying to get dimension information such as value, Arrowpoints, linePoints, location, name and type of that dimensions.
Below is my function that I worked to get the information

But the only info I am able to get is name and vertex points in mm
After investigation i found getValues function of class XCAFDimTolObjects_DimensionObject which is returing 0.

I have attached cpp file having code as well as image of the dimensions and the properties i am using to export my file from creo.

int getDimensionsData(Handle(TDocStd_Document) document) {
Handle(XCAFDoc_DimTolTool) m_gdtTool = XCAFDoc_DocumentTool::DimTolTool(document->Main());
Handle(XCAFDoc_ShapeTool) m_shapeTool = XCAFDoc_DocumentTool::ShapeTool(document->Main());

TDF_LabelSequence labels_datums, label_geoms, label_dims, label_dimTols, label_ding;
m_gdtTool->GetDatumLabels(labels_datums);
m_gdtTool->GetDimensionLabels(label_dims);
m_gdtTool->GetGeomToleranceLabels(label_geoms);

int datumSize = labels_datums.Length(); //getting 0
int dimSize = label_dims.Length(); //getting 1 since only step file have only one dimension
int geomSize = label_geoms.Length(); //getting 0

// Geometric Tolerances
for (int i = 1; i {
const TDF_Label& label_dim = label_dims.Value(i);

Handle(XCAFDoc_Dimension) aDimAttr;
label_dim.FindAttribute(XCAFDoc_Dimension::GetID(), aDimAttr);

if (!aDimAttr.IsNull())
{
Handle(XCAFDimTolObjects_DimensionObject) aDimObject = aDimAttr->GetObject();
Handle(TCollection_HAsciiString) name = aDimObject->GetPresentationName();

if (!name)
name = aDimObject->GetSemanticName();

double val = aDimObject->GetValue(); // getting 0.0000000000000000
double lowerTolVal = aDimObject->GetLowerTolValue(); // getting 0.0000000000000000
double lowerBoundVal = aDimObject->GetLowerBound(); // getting 0.0000000000000000
double upperTolVal = aDimObject->GetUpperTolValue(); // getting 0.0000000000000000
double upperBound = aDimObject->GetUpperBound(); // getting 0.0000000000000000

gp_Pnt lowerBoun = aDimObject->GetPoint(); // getting x,y,z as 0.0000000000000000
gp_Pnt lowerBou = aDimObject->GetPoint2(); // getting x,y,z as 0.0000000000000000
gp_Pnt lowerBo = aDimObject->GetPointTextAttach(); // getting x,y,z as 0.0000000000000000

{

}
}
if (name)

std::wstring nameStr = StrTool::str2wstr(ascNameStr.ToCString());
