cad.net 块裁剪边界反向修剪

Querying for XCLIP information inside AutoCAD using .NET 这里下面观众讨论了

How do I determine if an x-clip boundary is inverted?

看起来Autodesk忘记了通过API公开此设置,或将其包含在DXF输出中.
也许您可以通过调用 SpatialFilter.ClipVolumeIntersectsExtents() 来确定它,它的内容完全在边界之内.
该设置通过 DwgOutFields() 提交给DWG文件管理器，因此，如果所有其他操作均失败，则可以编写一个自定义AcDbDwgFiler来捕获该设置。

首先说明一下,根据以上的帖子,我们会得到一个消息是,桌子并没有封装好cad的块裁剪边界翻转部分.

然后我翻了翻api,在Acad2015版本上面是已经加了一个 SpatialFilter.Inverted 这个函数.

而我们低版本需要的就是重写出一个 Inverted ..

最后要进行刷新.

这样就完成了.

但是要注意下面的函数,它们只是个例子,没有提供撤销回滚的时候要刷新的操作...这个部分大家自己自行制作.

命令主函数部分:

    public static partial class Command_jjMoveBlockCropBoundary{//选择图块,进行反向裁剪  [CommandMethod("test", CommandFlags.Modal | CommandFlags.UsePickSet | CommandFlags.Redraw | CommandFlags.Session)]public static void test(){Database db = HostApplicationServices.WorkingDatabase;//当前的数据库Editor ed = Application.DocumentManager.MdiActiveDocument.Editor;var peo = new PromptEntityOptions(Environment.NewLine + "点选图块:"){AllowObjectOnLockedLayer = false,AllowNone = false};var gt = ed.GetEntity(peo);if (gt.Status != PromptStatus.OK){return;}using (Application.DocumentManager.MdiActiveDocument.LockDocument())//锁文档  用CommandFlags.Session就要锁,否则eLockViolation
            {using (Transaction tr = db.TransactionManager.StartTransaction()){var ent = tr.GetObject(gt.ObjectId, OpenMode.ForRead);if (ent is BlockReference acBlkRef){SpatialFilter blockBoundaryInfo = BlockBoundaryInfo(acBlkRef, tr);//块裁剪边界信息   if (blockBoundaryInfo != null){//直接设置为反向
                            blockBoundaryInfo.UpgradeOpen();
#if false //这个在2015以上版本有,但是下面的操作是通用的blockBoundaryInfo.Inverted = !blockBoundaryInfo.Inverted;
#endifvar fa = blockBoundaryInfo.Inverted(out XmDwgFiler xmDwgFiler);blockBoundaryInfo.SetInverted(xmDwgFiler);blockBoundaryInfo.DowngradeOpen();acBlkRef.UpgradeOpen();acBlkRef.RecordGraphicsModified(true);//记录图元已修改,这个之前要ent.UpgradeOpen()
                            acBlkRef.DowngradeOpen();}}tr.Commit();}}}

判断和设置部分.

        /// <summary>/// 边界是否为反向裁剪/// </summary>/// <param name="spatialFilter">裁剪信息</param>/// <returns></returns>public static bool Inverted(this SpatialFilter spatialFilter, out XmDwgFiler xmDwgFiler){xmDwgFiler = new XmDwgFiler();spatialFilter.DwgOut(xmDwgFiler);var f = xmDwgFiler.UInt16List[1];if (f != 1){return false;}else{return true;}}/// <summary>/// 设定反向裁剪/// </summary>/// <param name="spatialFilter">裁剪数据</param>/// <param name="xmDwgFiler">原始数据</param> /// <returns></returns>public static void SetInverted(this SpatialFilter spatialFilter, XmDwgFiler xmDwgFiler){if (xmDwgFiler.UInt16List[1] == 1){xmDwgFiler.UInt16List[1] = 0;}else{xmDwgFiler.UInt16List[1] = 1;}spatialFilter.DwgIn(xmDwgFiler);}
