XCLIP - No Boundary Found

Civil3DReminders_com — Fri, 12 Jun 2020 18:32:25 GMT

I'm attempting to XCLIP an External Reference DWG. The code appears to work, except for AutoCAD recognizing it. If I press the Remove Clipping Boundary from the ribbon, AutoCAD indicates "No clip boundary found." I have to create a new clipping boundary to remove the clipping boundary added via code.

I'm using code based on this blog post:

https://www.keanw.com/2010/11/adding-a-2d-spatial-filter-to-perform-a-simple-xclip-on-an-external-reference-in-autocad-using-net.html

Is this a known issue or is there a method that gives the expected results.

Using AutoCAD Civil 3D 2020.

public static bool AddXClip(Transaction tr, List<Point2d> points) { var doc = Application.DocumentManager.MdiActiveDocument; var db = doc.Database; var ed = doc.Editor; var typVals = new List<TypedValue> { new TypedValue((int)DxfCode.Operator, "<OR"), new TypedValue((int)DxfCode.Start, typeof(BlockReference)), new TypedValue((int)DxfCode.Start, "INSERT"), new TypedValue((int)DxfCode.Operator, "OR>") }; var xrefObjId = ed.GetEntityByTypes(typVals, "Select external reference to XCLIP: ", "", out Point3d pickPt); if (xrefObjId.IsNull) { return false; } try { var pt2DCollection = new Point2dCollection(); foreach (var pt in points) { pt2DCollection.Add(pt); } var acFilterDictName = "ACAD_FILTER"; var acSpatialName = "SPATIAL"; var blkRef = xrefObjId.GetObject(OpenMode.ForWrite) as BlockReference; var acSpatialFilterDef = new SpatialFilterDefinition(pt2DCollection, blkRef.Normal, 0.0, 0.0, 0.0, true); var acSpatialFilter = new SpatialFilter { Definition = acSpatialFilterDef }; if (blkRef.ExtensionDictionary.IsNull) { blkRef.CreateExtensionDictionary(); } var extensionDict = blkRef.ExtensionDictionary.GetObject(OpenMode.ForWrite) as DBDictionary; if (extensionDict.Contains(acFilterDictName)) { var filterDict = extensionDict.GetAt(acFilterDictName).GetObject(OpenMode.ForWrite) as DBDictionary; if (filterDict.Contains(acSpatialName)) { filterDict.Remove(acSpatialName); } filterDict.SetAt(acSpatialName, acSpatialFilter); } else { var filterDict = new DBDictionary(); extensionDict.SetAt(acFilterDictName, filterDict); tr.AddNewlyCreatedDBObject(filterDict, true); filterDict.SetAt(acSpatialName, acSpatialFilter); } tr.AddNewlyCreatedDBObject(acSpatialFilter, true); return true; } catch (System.Exception ex) { return false; } }

Thanks!

Hi,

I have the same problem when trying to clip a block reference. I've been trying to find the solution and have come across your topic. Have you found the solution yet? If you have one, please share it. I can't find any information about this problem.

When I saved and reopened the drawing, it fixed the problem. But it's inconvenient when creating multiple clippings because the drawing doesn't show correctly.

Thank you.
