Example

    GS::Array<API_ElemCategory> categoryList;
    ACAPI_Database (APIDb_GetElementCategoriesID, &categoryList);

    categoryList.Enumerate ([&] (const API_ElemCategory& category) {
        if (category.categoryID == API_ElemCategory_StructuralFunction || category.categoryID == API_ElemCategory_Position || category.categoryID == API_ElemCategory_ElementClassification) {
            GS::Array<API_ElemCategoryValue> categoryValueList;
            ACAPI_Database (APIDb_GetElementCategoryValuesID, (void*) &category, &categoryValueList);
            if (!categoryValueList.IsEmpty ()) {
                if (changeDefaults) {
                    err = ACAPI_Element_SetCategoryValueDefault (element.header.type, category,   categoryValueList[categoryValueList.GetSize () - 1]);
                    if (err != NoError)
                        ErrorBeep ("ACAPI_Element_SetCategoryValueDefault ()", err);
                } else {
                    err = ACAPI_Element_SetCategoryValue (element.header.guid, category,    categoryValueList[0]);
                    if (err != NoError)
                        ErrorBeep ("ACAPI_Element_SetCategoryValue ()", err);
