Why do dimensions disapear when close and open map.

I create dimension feature class I change the style, add dimensions to my map but when I reopen the map the dimensions are gone? Is there documentation I can read about this behavior. I am also interested in creating dimensions with python code but I have found no examples.
Update- I created a button that creates a dim with style inside a geodatabase, now when I close and open the map the dimensions are just red polygons.
after close and open arcmap before close and open
Here is the code I sued to create the dimension feature class.
IFeatureLayer pFeatureLayer = (IFeatureLayer)pBoundaryLayer;
IFeatureClass pFeatureClass = pFeatureLayer.FeatureClass;
string strCatalogPath = GetCatalogPath(pFeatureClass);
IWorkspace pWorkspace = FileGDBWorkspaceFromPropertySet(strCatalogPath);
IObjectClassDescription ocDescription = new DimensionClassDescription();
IFields pRequiredFields = ocDescription.RequiredFields;
int intShapeFieldPosition = pRequiredFields.FindField("Shape");
IField pShapeField = pRequiredFields.get_Field(intShapeFieldPosition);
IGeometryDef pGeomDef = pShapeField.GeometryDef;
IGeometryDefEdit pGeomDefEdit = (IGeometryDefEdit)pGeomDef;
ISpatialReferenceFactory3 pSpatRefFac = new SpatialReferenceEnvironmentClass();
ISpatialReference pSpatRef = pSpatRefFac.CreateSpatialReference(6578);
IProjectedCoordinateSystem pProSpatRef = (IProjectedCoordinateSystem)pSpatRef;
ILinearUnit linUnit = pProSpatRef.CoordinateUnit;
pGeomDefEdit.SpatialReference_2 = pSpatRef;
IFeatureWorkspace pFeatWorkspace = (IFeatureWorkspace)pWorkspace;
string pName = "DIM";
IFeatureClass pNewFeatureClass = pFeatWorkspace.CreateFeatureClass(pName.ToString(), pRequiredFields, ocDescription.InstanceCLSID, ocDescription.ClassExtensionCLSID, esriFeatureType.esriFTDimension, "Shape", "");

}Is there something I can add to make this layer persist?
