revi在橋梁中的應用二次開發(fā)-族

Revit在橋梁中的應用二次開發(fā)篇（1）——族建模篇簡單講了怎么在revit軟件中手動建橋梁模型，更多的基礎操作的內容可以直接看revit在建筑中應用的相關教程，其實也是相通的，沒必要多講。這次誠意滿滿，花了兩天時間專門研究二次開發(fā)中族的應用。以下代碼親測可試，結合《AUTODESKREVIT二次開發(fā)基礎教程》可以獲得更好的效果。因為書本上都是一些代碼片段，而且是基于2015版的，在2016版的revit上部分代碼跑不了。我也嘗試了很久，終于基本上搞通了族相關的語法?；A知識直接看書，這里直接上代碼。書里的代碼片段可以想辦法插到完整代碼中運行。1、找到族實例

//用id找到族實例2、拿到族文檔//拿到族文檔

DocumentfamilyDoc=revitDoc.EditFamily(familyInstance.Symbol.Family);

if(!familyDoc.IsFamilyDocument)

{

TaskDialog.Show("錯誤3","familyDoc不是族文檔！");

}

else

{

TaskDialog.Show("revit","familyDoc是族文檔！");

}3、修改族類型名稱（完整代碼）usingSystem;usingSystem.Collections.Generic;usingSystem.Linq;usingSystem.Text;usingSystem.Threading.Tasks;usingAutodesk.Revit.UI;usingAutodesk.Revit.DB;usingAutodesk.Revit.UI.Selection;usingAutodesk.Revit.ApplicationServices;namespace修改族類型名稱{

[Autodesk.Revit.Attributes.Transaction(Autodesk.Revit.Attributes.TransactionMode.Manual)]

[Autodesk.Revit.Attributes.Journaling(Autodesk.Revit.Attributes.JournalingMode.NoCommandData)]

[Autodesk.Revit.Attributes.Regeneration(Autodesk.Revit.Attributes.RegenerationOption.Manual)]

publicclassClass1:IExternalCommand

{

publicResultExecute(ExternalCommandDatacommandData,refstringmessage,ElementSetelements)

{

DocumentrevitDoc=commandData.Application.ActiveUIDocument.Document;

//取得文檔

ApplicationrevitApp=commandData.Application.Application;

//取得應用程序

Selectionsel=commandData.Application.ActiveUIDocument.Selection;

Referenceref1=sel.PickObject(ObjectType.Element,"選擇一個族實例");

//得到當前選擇的文檔

Documentdoc=commandData.Application.ActiveUIDocument.Document;

//族實例

FamilyInstancefamilyIns=doc.GetElement(ref1)asFamilyInstance;

FamilySymbolsymbol=familyIns.Symbol;

Transactiontransaction=newTransaction(doc);

//打開關閉子程序

transaction.Start("改變族類型名稱");

symbol.Name="new"+symbol.Name;

transaction.Commit();

returnResult.Succeeded;

}

}}4、刪除一個族參數

[Autodesk.Revit.Attributes.Transaction(Autodesk.Revit.Attributes.TransactionMode.Manual)]

[Autodesk.Revit.Attributes.Journaling(Autodesk.Revit.Attributes.JournalingMode.NoCommandData)]

[Autodesk.Revit.Attributes.Regeneration(Autodesk.Revit.Attributes.RegenerationOption.Manual)]

publicclassClass1:IExternalCommand

{

publicResultExecute(ExternalCommandDatacommandData,refstringmessage,ElementSetelements)

{

DocumentrevitDoc=commandData.Application.ActiveUIDocument.Document;

//取得文檔

ApplicationrevitApp=commandData.Application.Application;

//取得應用程序

//選擇一個族實例

Selectionsel=commandData.Application.ActiveUIDocument.Selection;

Referenceref1=sel.PickObject(ObjectType.Element,"選擇一個族實例");

FamilyInstancefamilyIns=revitDoc.GetElement(ref1)asFamilyInstance;

FamilySymbolsymbol=familyIns.Symbol;

//得到族文檔

DocumentfamilyDoc=revitDoc.EditFamily(symbol.Family);

//取得FamilyManager，注意這里只能從族文檔中取得FamilyManager,然后修改參數

FamilyManagerfamilyManager=familyDoc.FamilyManager;

IList<FamilyParameter>faparms=familyManager.GetParameters();

TaskDialog.Show("FamilyParameter",faparms.First().Definition.Name);

Transactiontrans=newTransaction(familyDoc,"RemoveParameter");

trans.Start();

familyManager.RemoveParameter(faparms.First());

trans.Commit();

familyDoc.LoadFamily(revitDoc,newOpt());

returnResult.Succeeded;

}

}}//族載入時覆蓋并修改族參數

publicclassOpt:IFamilyLoadOptions

{

publicboolOnFamilyFound(boolfamilyInUse,outbooloverwriteParameterValues)

{

overwriteParameterValues=true;

returntrue;

}

publicboolOnSharedFamilyFound(FamilysharedFamily,boolfamilyInUse,outFamilySourcesource,outbooloverwriteParameterValues)

{

source=FamilySource.Project;

overwriteParameterValues=true;

returntrue;

}

}4、遍歷族參數usingSystem;usingSystem.Collections.Generic;usingSystem.Linq;usingSystem.Text;usingSystem.Threading.Tasks;usingAutodesk.Revit.UI;usingAutodesk.Revit.DB;usingAutodesk.Revit.UI.Selection;usingAutodesk.Revit.ApplicationServices;namespace遍歷族參數{

[Autodesk.Revit.Attributes.Transaction(Autodesk.Revit.Attributes.TransactionMode.Manual)]

[Autodesk.Revit.Attributes.Journaling(Autodesk.Revit.Attributes.JournalingMode.NoCommandData)]

[Autodesk.Revit.Attributes.Regeneration(Autodesk.Revit.Attributes.RegenerationOption.Manual)]

publicclassClass1:IExternalCommand

{

publicResultExecute(ExternalCommandDatacommandData,refstringmessage,ElementSetelements)

{

DocumentrevitDoc=commandData.Application.ActiveUIDocument.Document;

//取得文檔

UIApplicationuiApp=commandData.Application;

ApplicationrevitApp=commandData.Application.Application;

//取得應用程序

//取得選擇的元素

Selectionsel=uiApp.ActiveUIDocument.Selection;

Referenceref1=sel.PickObject(ObjectType.Element,"pleasepickafamilyinstance");

Documentdoc=uiApp.ActiveUIDocument.Document;

Elementelem=doc.GetElement(ref1);

//遍歷元素的參數

stringstrParamInfo=null;

foreach(Parameterparaminelem.Parameters)

{

if(param.AsValueString()!=null)

strParamInfo+=param.Definition.Name+"valueis:"+param.AsValueString()+"\n";

else

strParamInfo+=param.Definition.Name+"valueis:"+param.AsString()+"\n";

}

TaskDialog.Show("REVIT",strParamInfo);

returnResult.Succeeded;

}

}}5、獲得指定族參數并修改參數，這里以窗戶的底高度為例。這里用兩種方法找到指定參數，尤其是用名稱找到指定參數尤其要注意，舊版本的get_Parameter（）已經不能用了usingSystem.Text;usingSystem.Threading.Tasks;usingAutodesk.Revit.UI;usingAutodesk.Revit.DB;usingAutodesk.Revit.UI.Selection;usingAutodesk.Revit.ApplicationServices;namespace獲得指定參數并修改參數{

[Autodesk.Revit.Attributes.Transaction(Autodesk.Revit.Attributes.TransactionMode.Manual)]

[Autodesk.Revit.Attributes.Journaling(Autodesk.Revit.Attributes.JournalingMode.NoCommandData)]

[Autodesk.Revit.Attributes.Regeneration(Autodesk.Revit.Attributes.RegenerationOption.Manual)]

publicclassClass1:IExternalCommand

{

publicResultExecute(ExternalCommandDatacommandData,refstringmessage,ElementSetelements)

{

DocumentrevitDoc=commandData.Application.ActiveUIDocument.Document;

//取得文檔

UIApplicationuiApp=commandData.Application;

ApplicationrevitApp=commandData.Application.Application;

//取得應用程序

//取得選擇的元素

Selectionsel=uiApp.ActiveUIDocument.Selection;

Referenceref1=sel.PickObject(ObjectType.Element,"選擇一個窗族");

Elementelem=revitDoc.GetElement(ref1);

//獲得族實例

FamilyInstancefamilyInstance=elemasFamilyInstance;

//遍歷元素的參數

stringstrParamInfo=null;

////方法一：使用parameterId來找到參數

//Parameterparam=familyInstance.get_Parameter(BuiltInParameter.INSTANCE_SILL_HEIGHT_PARAM);

//strParamInfo+=param.Definition.Name+"valueis:"+param.AsValueString()+"\n";

//方法二：使用名稱來找到參數,因為revit2016為了避免得到重復的名字，只能用GetParameters得到一個集合，如果你只用唯一的名字，那只用取list[0]就可以了

IList<Parameter>list=familyInstance.GetParameters("底高度");

Parameterparam=list[0];

strParamInfo+=param.Definition.Name+"valueis:"+param.AsValueString()+"\n";

//方法三：見下圖

//修改參數的值

Transactiontransaction=newTransaction(revitDoc);

//打開子程序，修改參數，然后關閉子程序

transaction.Start("改變族類型名稱");

param.Set(10);

//注意，這里單位是英寸，10英寸等于3048mm

transsactioon.Commiit();

TaskDDialogg.Show("REVIIT",strPaaramInnfo);

returrnResullt.Succeeeded;;

}
