如何在 AutoCAD 中将此列表限制为仅纸质 space 布局？

Question

这是一个在命令行中显示布局列表的简单命令window:

public void TestVP()
{
    try
    {
        _AcAp.Document acDoc = _AcAp.Application.DocumentManager.MdiActiveDocument;
        _AcDb.Database acCurDb = acDoc.Database;

        _AcEd.Editor editor = _AcAp.Application.DocumentManager.MdiActiveDocument.Editor;
        using (_AcDb.Transaction acTrans = _AcDb.HostApplicationServices.WorkingDatabase.TransactionManager.StartTransaction())
        {
            _AcDb.BlockTable acBlkTbl;
            acBlkTbl = acTrans.GetObject(acCurDb.BlockTableId, _AcDb.OpenMode.ForRead) as _AcDb.BlockTable;

            foreach(_AcDb.ObjectId id in acBlkTbl)
            {
                _AcDb.BlockTableRecord btRecord = (_AcDb.BlockTableRecord)acTrans.GetObject(id, _AcDb.OpenMode.ForRead);
                if(btRecord.IsLayout)
                {
                    _AcDb.Layout acLayout = (_AcDb.Layout)acTrans.GetObject(btRecord.LayoutId, _AcDb.OpenMode.ForRead);
                    editor.WriteMessage(acLayout.LayoutName + "\n");
                }
            }

            acTrans.Commit();
        }
    }
    catch (System.Exception ex)
    {
        _AcAp.Application.ShowAlertDialog(
            string.Format("\nError: {0}\nStacktrace: {1}", ex.Message, ex.StackTrace));
    }
}

目前它还包括模型布局。我不想这样。如何将布局列表限制为 paper space 布局？

即使我像这样使用 LayoutManager 这样做：

using (_AcDb.Transaction acTrans = _AcDb.HostApplicationServices.WorkingDatabase.TransactionManager.StartTransaction())
{
    _AcDb.DBDictionary layoutDic = acTrans.GetObject(acCurDb.LayoutDictionaryId, _AcDb.OpenMode.ForRead) as _AcDb.DBDictionary;
    foreach(_AcDb.DBDictionaryEntry entry in layoutDic)
    {
        _AcDb.ObjectId layoutId = entry.Value;
        _AcDb.Layout layout = acTrans.GetObject(layoutId, _AcDb.OpenMode.ForRead) as _AcDb.Layout;
        editor.WriteMessage(String.Format("{0}--> {1}", Environment.NewLine, layout.LayoutName));
    }

    acTrans.Commit();
}

我仍然得到：

Active Layout is : Model Number of Layouts is : 3
--> Layout1
--> Layout2
--> Model

我不想针对“模型”的布局名称进行测试。

Answer 1

这是我想出的：

public void TestVP()
{
    try
    {
        _AcAp.Document acDoc = _AcAp.Application.DocumentManager.MdiActiveDocument;
        _AcDb.Database acCurDb = acDoc.Database;
        _AcEd.Editor editor = _AcAp.Application.DocumentManager.MdiActiveDocument.Editor;
        _AcDb.LayoutManager layoutMgr = _AcDb.LayoutManager.Current;

        editor.WriteMessage(String.Format("{0}Active Layout is : {1}", Environment.NewLine, layoutMgr.CurrentLayout));
        editor.WriteMessage(String.Format("{0}Number of Layouts is : {1}", Environment.NewLine, layoutMgr.LayoutCount));

        using (_AcDb.Transaction acTrans = _AcDb.HostApplicationServices.WorkingDatabase.TransactionManager.StartTransaction())
        {
            _AcDb.BlockTable bt = acCurDb.BlockTableId.GetObject(_AcDb.OpenMode.ForRead) as _AcDb.BlockTable;
            _AcDb.BlockTableRecord ms = acTrans.GetObject(bt[_AcDb.BlockTableRecord.ModelSpace], _AcDb.OpenMode.ForRead) as _AcDb.BlockTableRecord;
            _AcDb.DBDictionary layoutDic = acTrans.GetObject(acCurDb.LayoutDictionaryId, _AcDb.OpenMode.ForRead) as _AcDb.DBDictionary;
            foreach(_AcDb.DBDictionaryEntry entry in layoutDic)
            {
                _AcDb.ObjectId layoutId = entry.Value;
                _AcDb.Layout layout = acTrans.GetObject(layoutId, _AcDb.OpenMode.ForRead) as _AcDb.Layout;
                editor.WriteMessage(String.Format("{0}--> {1}", Environment.NewLine, layout.LayoutName));

                _AcDb.BlockTableRecord layoutBlkTbl = acTrans.GetObject(layout.BlockTableRecordId, _AcDb.OpenMode.ForRead) as _AcDb.BlockTableRecord;
                if(layoutBlkTbl.Id != ms.Id)
                    editor.WriteMessage(" (PaperSpace)");
                
            }

            acTrans.Commit();
        }
    }
    catch (System.Exception ex)
    {
        _AcAp.Application.ShowAlertDialog(
            string.Format("\nError: {0}\nStacktrace: {1}", ex.Message, ex.StackTrace));
    }
}

我得到的输出是：

Active Layout is : Model
Number of Layouts is : 3
--> Layout1 (PaperSpace)
--> Layout2 (PaperSpace)
--> Model

我只是将 Layout 的 Id 与 Model Space object Id。可能有更简单的方法。但至少我现在可以将我的列表限制为纸质 space 布局。

如何在 AutoCAD 中将此列表限制为仅纸质 space 布局？

How do I limit this list to only paper space layouts in AutoCAD?
