[请教]如何通过图形句柄选择并缩放到图形呀
用vba很简单Public Sub FindHandle()
Dim ent As AcadEntity
Dim returnObj As AcadObject
Dim returnStr As String
Dim MinP As Variant, MaxP As Variant
On Error GoTo lblerr
returnStr = ThisDrawing.Utility.GetString(False, "输入实体句柄：")
Set returnObj = ThisDrawing.HandleToObject(returnStr)
Set ent = returnObj
ent.Highlight True
ent.GetBoundingBox MinP, MaxP
ZoomWindow MinP, MaxP
lblerr:
End Sub
但是现在需要用c#，我找不到合适的函数，现在只做到了选择元素（自己觉得效率很低），但是不知道怎么平移缩放到该元素：
Database db = Autodesk..ApplicationServices.Application.DocumentManager.MdiActiveDocument.Database;
Transaction trans = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument.Database.TransactionManager.StartTransaction();
try
{
long l = long.Parse(textBox_Element_Handle.Text, System.Globalization.NumberStyles.HexNumber);
 romptSelectionResult prSelectionRes = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument.Editor.SelectAll();
if (prSelectionRes.Status != PromptStatus.OK)
throw new System.Exception("未找到图形元素!");
ObjectId[] ois = prSelectionRes.Value.GetObjectIds();
foreach (ObjectId objId in ois)
{
Entity en = (Entity)trans.GetObject(objId, OpenMode.ForRead);
if(en.Handle.Value == l)
{
/*平移缩放到该元素*/
/*知道的帮忙啊*/
en.Highlight(new FullSubentityPath(new ObjectId[]{en.ObjectId}, new SubentityId(SubentityType.Null,0)),true);
return;
}
}
MessageBox.Show(@"未找到该句柄对应的图形元素!");
}
catch (System.Exception Ex)
{
MessageBox.Show(Ex.Message, @"错误");
}
finally
{
trans.Dispose();
}
请问有谁可以帮助我呢，或者有更简单的办法：）
受教了！！！
