cad.net 块裁剪边界反向修剪

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; #endif var 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(); } } } View Code   判断和设置部分. /// /// 边界是否为反向裁剪 /// /// 裁剪信息 /// 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; } } /// /// 设定反向裁剪 /// /// 裁剪数据 /// 原始数据 /// public static void SetInverted(this SpatialFilter spatialFilter, XmDwgFiler xmDwgFiler) { if (xmDwgFiler.UInt16List[1] == 1) { xmDwgFiler.UInt16List[1] = 0;
