如何用vb.net编程在cad图形中插入dwg图块?
Dim ppr As PromptPointResult = ed.GetPoint("请选择插入点:")
Dim pt As Point3d = ppr.Value
utility.WriteToEditor(pt.ToString())
Dim pidBlock As New PIDBlock()
'自己定义的图块类,保存图块的路径和名称
pidBlock.Name = "sample"
pidBlock.Path = blockPath "b_sample.dwg"
Using blkDb As New Database(False, True)
'read drawing
blkDb.ReadDwgFile(pidBlock.Path, System.IO.FileShare.Read, True, Nothing)
blkDb.CloseInput(True)
Using docLock As DocumentLock = doc.LockDocument()
'多文档要先这样,否则报至命错误
Using t As Transaction = doc.TransactionManager.StartTransaction()
'insert it as a new block
Dim idBTR As ObjectId = doc.Database.Insert(pidBlock.Name, blkDb, False)
'create a ref to the block
Dim bt As BlockTable = DirectCast(t.GetObject(doc.Database.BlockTableId, OpenMode.ForRead), BlockTable)
Dim btr As BlockTableRecord = DirectCast(t.GetObject(bt(BlockTableRecord.ModelSpace), OpenMode.ForWrite), BlockTableRecord)
Using bref As New BlockReference(pt, idBTR)
btr.AppendEntity(bref)
t.AddNewlyCreatedDBObject(bref, True)
End Using
t.Commit()
End Using
End Using
End Using
