VB。net/edit插入动态
我会用VB。net编辑正常插入块引用的属性文本字符串,但它不适用于动态块,请帮助。致以最诚挚的问候。 Public Sub UpdateAtt(ByVal tr As Transaction, ByVal objID As ObjectId)
Dim br As BlockReference = DirectCast(tr.GetObject(objID, OpenMode.ForWrite), BlockReference)
Dim btr As BlockTableRecord = DirectCast(tr.GetObject(br.DynamicBlockTableRecord, OpenMode.ForWrite), BlockTableRecord)
For Each attID As ObjectId In btr
Dim ent As DBObject = tr.GetObject(attID, OpenMode.ForWrite)
If TypeOf ent Is AttributeDefinition Then
Dim AttDef As AttributeDefinition = ent
If AttDef.Tag = "SH" Then AttDef.TextString = "111"
End If
Next
End Sub
如果br不是动态块,br的属性可以通过br的属性集合进行编辑,但它不适用于动态块,因此我认为这项工作可以通过属性定义来完成,但也不起作用,感谢阅读。。。
