二次开发笔记

1.

选中图元

1.1

事先选择某类图元

（

Wall

）

ication

revit = ation;

ElementSet

collection = new

ElementSet();

ElementSet

selWall = new

ElementSet();

foreach (ElementId elementId in mentIds())

{

(ment(elementId));

//

选中的原件

}

foreach (Element ele in sel)

{

Wall wall = ele as Wall;

//

如果为墙

if (wall !=null)

{

(ele);

}

}

1.2.

通过交互方式

1.2.1

用矩形框选择图元

所用方法：

PickElementsByRectangle()

using c;

//

声明引用命名空间，

Ilist

UIDocument uidoc = UIDocument;

ElementSet collector = new ElementSet();

IList elemList = ementsByRectangle();

//

矩形框的应用

string info =

所选图元：

foreach (Element elem in elemList)

{

(elem);

info +=

}

(

return ded;

1.2.2

用点击选择图元

所用方法：

PickObject(t)

using ion;

//

声明引用命名空间，

ObjectType

UIDocument uidoc = UIDocument;

Reference hasPickOne = ject(t);

Element elem = ment(tId);

string info =

所选图元：

info +=

(

还存在其它用法：

ject (ObjectType, String)

//string

为提示

PickObjects (ObjectType)

//

允许选择多个元素

1.2.3

选择及过滤

UIDocument uidoc = UIDocument;

ISelectionFilter selFilter = new MassSelectionFilter();

IList eList = ementsByRectangle(selFilter) as IList;

string info =

选择了以下的墙：

foreach(Element elem in eList)

{

info +=

}

(

return ded;

public class MassSelectionFilter : ISelectionFilter

{

public bool AllowElement(Element elem)

{

return elem is Wall;

//

选择了墙

}

public bool AllowReference(Reference reference, XYZ position)

{

throw new NotImplementedException();

//

第二个条件

}

}

2.

加载族并创建实例

UIApplication

m_application;

UIDocument

m_document;

m_application = ation;

m_document = m_UIDocument;

2.1.

加载族

1) m_document .milySymbol (

FullPath

, symbolName,

out

loadedfamilySymbol);

2) m_document .mily (

FullPath

,

out

loadedfamily);

第一种用来加载族类型，第二种用来加载族，返回的
