[求助]可以說明collection的應用,或推薦閱讀嗎?
做了含attribute的Block但重覆引用時需把attribute.rotation,height上回站上mccad大大教了GetSubEntity 直接由螢幕點選更改attribute,
但有些狀況必需在InsertBlock之前先改變已定義block的attribute.rotation
在 Joe Sutphin的 2006 VBA a programmer's Reference書上
查到先選入collection中
Function GetAttrib(oBlock As AcadBlock) As Collection
Dim objEntAs AcadEntity
Dim objAttribute As AcadAttribute
Dim coll As New Collection
For Each objEnt In oBlock
If objEnt.ObjectName = "AcDbAttributeDefinition" Then
Set objAttribute = objEnt
coll.Add objAttribute
End If
Next objEnt
Set GetAttrib = coll
End Function
再用 for each ObjAttribute in coll .......捉到attribute更改
請問
1.這是正確而有效率的方法嗎?
2.很少看書上寫collection用法,麻煩前輩指點一二,或推薦閱讀,
謝謝!!
