Quantification 国外有的叫定量 我们国内一些施工方叫工程量。
通过TakeOff API的开发者有机会获得更多的数据和数据可通过图形用户界面。
1 添加Navisworks的Api
Autodesk.Navisworks.Takeoff.dll
2获取量一般是由随模型一起有个Access数据库.所有数据存在该数据库里面。当然也可以是基本数据库..
3使用C＃和使用Autodesk.Navisworks.Api.Takeoff命名空间则扩展方法：
DocumentExtensions.GetTakeoff
例如 C# 代码:
DocumentTakeoff docTakeoff =
Autodesk.Navisworks.Api.Application.MainDocument.Takeoff as DocumentTakeoff; DocumentTakeoff docTakeoff2 =
Autodesk.Navisworks.Api.Application.MainDocument.GetTakeoff();
注：下面有关键字 table 都是数据库里的表。
DocumentExtensions类的地方扩展到文档类的DocumentTakeoff文档部件类。
DocumentTakeoff提供对与起飞相关的各种文档部分。
ItemGroupTable配置信息ItemGorupTable。
ItemTable配置信息ItemTable。
ObjectResourceTable配置信息ObjectResourceTable。
ObjectStepTable配置信息ObjectStepTable。
ObjectTable配置信息ObjectTable。
ResourceGroupTable配置信息ResourceGroupTable。
ResourceTable配置信息ResourceTable。
StepResourceTable配置信息StepResourceTable。
StepTable配置信息StepTable。
TakeoffTable为所有表共有的特征共同的基类。
TakeoffTableSelection表示在一个表中选择。
TakeoffColumnDefinition起飞表中的固定列的定义。
TakeoffProjectSettings Access项目设置。
TakeoffSelection切入点每个表的选择。
TakeoffSelectionChangeEventArgs用于TakeoffSelection Changed事件通过哪些表被修改。
TakeoffSheetIds访问表编号。
TakeoffVariable代表一个变量。
TakeoffVariableCollection代表配置列的行数据。
TakeoffVariableDefinition起飞表变量列的定义。
的配置列定义TakeoffVariableDefinitionCollection集合
4使用标准的SQL查询数据
Int64 GetLastInsertRowId()
{
DocumentTakeoff docTakeoff = Autodesk.Navisworks.Api.Application.MainDocument.GetTakeoff();
using (NavisworksCommand cmd = docTakeoff.Database.Value.CreateCommand())
{
//use SELECT ... FROM ... WHERE ... sql for query.
//last_insert_rowid() is a stored function used to retrieve the rowid of the last insert row
cmd.CommandText = "select last_insert_rowid()";
using (NavisWorksDataReader dataReader = cmd.ExecuteReader())
{
Int64 lastId = -;
if (dataReader.Read())
{
Int64.TryParse(dataReader[].ToString(), out lastId);
}
return lastId;
}
}
}
5使用标准的SQL创建目录
Int64 InsertItem(Int64? parent, String name, String description, String wbs, Int32 color, Double transparency)
{
Debug.Assert(name != null);
DocumentTakeoff docTakeoff = Autodesk.Navisworks.Api.Application.MainDocument.GetTakeoff();
ItemTable table = docTakeoff.Items;
Debug.Assert(table != null); //Directly operate on database
//Database schema entry: TakeoffTable
//INSERT INTO TABLE(COL1,COL2,COL3...) VALUES(V1,V2,V3...);
String sql = "INSERT INTO TK_ITEM(parent, name, description, wbs, color, transparency) VALUES(@parent, @name, @description,@wbs, @color,@transparency)";
//Modification must be surrounded by NavisworksTransaction
using (NavisworksTransaction trans = docTakeoff.Database.BeginTransaction(DatabaseChangedAction.Edited))
{
using (NavisworksCommand cmd = docTakeoff.Database.Value.CreateCommand())
{
NavisworksParameter p = cmd.CreateParameter();
p.ParameterName = "@parent";
if (parent.HasValue)
p.Value = parent.Value;
else
p.Value = null;
cmd.Parameters.Add(p); p = cmd.CreateParameter();
p.ParameterName = "@name";
p.Value = name;
cmd.Parameters.Add(p); p = cmd.CreateParameter();
p.ParameterName = "@description";
p.Value = description;
cmd.Parameters.Add(p); p = cmd.CreateParameter();
p.ParameterName = "@wbs";
p.Value = wbs;
cmd.Parameters.Add(p); p = cmd.CreateParameter();
p.ParameterName = "@color";
p.Value = color;
cmd.Parameters.Add(p); p = cmd.CreateParameter();
p.ParameterName = "@transparency";
p.Value = transparency;
cmd.Parameters.Add(p); cmd.CommandText = sql;
cmd.ExecuteNonQuery();
}
trans.Commit();
}
return GetLastInsertRowId();
}
6复制使用类来创建一个takeOff
Int64 DoTakeoff(Int64 itemId, Guid modelItemGuid)
{
DocumentTakeoff docTakeoff = Autodesk.Navisworks.Api.Application.MainDocument.GetTakeoff();
List<Autodesk.Navisworks.Api.ModelItem> items = Autodesk.Navisworks.Api.Application.MainDocument.Models.RootItemDescendantsAndSelf.WhereInstanceGuid(modelItemGuid).ToList();
Int64 lastId = -;
if (items.Count != )
{
using (NavisworksTransaction trans = docTakeoff.Database.BeginTransaction(DatabaseChangedAction.Edited))
{
docTakeoff.Objects.InsertModelItemTakeoff(itemId, items[]);
//Quantification UI actually expect the takeoff to have a non-empty wbs, so better to set the wbs for it using the sql way
lastId = GetLastInsertRowId();
Debug.Assert(lastId > );
using (NavisworksCommand cmd = docTakeoff.Database.Value.CreateCommand())
{
//UPDATE Object set WBS = value WHERE id = lastId;
cmd.CommandText = "UPDATE TK_OBJECT SET wbs = @wbs WHERE id = @id";
NavisworksParameter p = cmd.CreateParameter();
p.ParameterName = "@wbs";
p.Value = ;
cmd.Parameters.Add(p); p = cmd.CreateParameter();
p.ParameterName = "@id";
p.Value = lastId;
cmd.Parameters.Add(p); cmd.ExecuteNonQuery();
}
trans.Commit();
} }
return lastId;
}
7使用类查询和修改数据
void UpdateTakeoffValue(Int64 objectId)
{
DocumentTakeoff docTakeoff = Autodesk.Navisworks.Api.Application.MainDocument.GetTakeoff();
//TakeoffVariableCollection TakeoffVariable are the entrance for read/update of the variables
TakeoffVariableCollection variableCollection = docTakeoff.Objects.SelectInputVariables(objectId);
Int32 lengthIndex = variableCollection.Find("ModelLength");
if (lengthIndex != -)
{
TakeoffVariable lengthVariable = variableCollection.GetItem(lengthIndex);
if (lengthVariable.IsAbleToSetValue)
{
lengthVariable.Value = Autodesk.Navisworks.Api.VariantData.FromDouble(5.6);
using (NavisworksTransaction trans = docTakeoff.Database.BeginTransaction(DatabaseChangedAction.Edited))
{
docTakeoff.Objects.UpdateInputVariables(objectId, variableCollection);
trans.Commit();
}
}
}
}
8选择在不同层次的元素在层次结构中
void SelectUIItem(Int64 itemId)
{
TakeoffSelection takeoffSelection = Autodesk.Navisworks.Api.Application.MainDocument.GetTakeoff().CurrentSelection;
takeoffSelection.BeginEdit();
takeoffSelection.Items.Clear();
takeoffSelection.ItemGroups.Clear();
takeoffSelection.StepResources.Clear();
takeoffSelection.Steps.Clear();
takeoffSelection.Items.Add(itemId);
takeoffSelection.EndEdit();
}
