Failed to perform the Boolean operation

Hope everyone is doing well, the operation I need to execute is a intersection between the room solid space and a solid extrusion from wall faces. In my las post I solved a similar issue by placing a single wall and editing the profile:

Unfortunately, in this next scenario I have a completely different kitchen layout and the problem comes up with the dining room:

this is a small piece of code:

//Set BoundarySegments Options SpatialElementBoundaryOptions sebOptions = new SpatialElementBoundaryOptions{ SpatialElementBoundaryLocation= SpatialElementBoundaryLocation.Finish }; //Eliminate or ignore null room location List<SpatialElement> allRoomsInModel = new FilteredElementCollector(doc).OfClass(typeof(SpatialElement)).WhereElementIsNotElementType().Cast<SpatialElement>().Where(x => x.Category.Name == "Rooms" && x.Location != null).ToList(); if (allRoomsInModel.Any()) { foreach (SpatialElement element in allRoomsInModel) { Room room = element as Room; double roomWallFinishArea = 0; if (room != null ) { if (room.Name != "DINING 99") { continue; } SpatialElementGeometryResults results2 = cal.CalculateSpatialElementGeometry(room); Solid roomSolid2 = results2.GetGeometry(); //GetSolid from spatial geometry List<double> areas = new List<double>(); #region 2.3) Wall Finish foreach (Face roomFace in roomSolid2.Faces) { // Filter spatial room Face by same wall Id from wall retrieved from bounding segment, instead of doing FaceNormal.Z != 1 ...etc. IList<SpatialElementBoundarySubface> boundaryGeometryInfoList = results2.GetBoundaryFaceInfo(roomFace);//it will retrieve INFO for geometry boundary that define this specific spatial roomFace foreach (SpatialElementBoundarySubface boundaryGeometryInfo in boundaryGeometryInfoList)//for each wall Info get Face info { if (boundaryGeometryInfo.SubfaceType == SubfaceType.Side) //Work with boundary geometry info that is a side face type { //get element that gave rise to this geometry face <> wall face Wall wall = doc.GetElement(boundaryGeometryInfo.SpatialBoundaryElement.HostElementId) as Wall; if (wall != null) { //Face of the bounding wall () Face wallFace = boundaryGeometryInfo.GetBoundingElementFace(); if (wallFace is PlanarFace) { //planarFace of the bounding wall PlanarFace planarWallFc = wallFace as PlanarFace; if (!areas.Contains(wallFace.Area)) { //tailorBird.tessellateFace(wallFace,doc); #region 2.3.1). Create Solid from opening inserts in each boundary wall IList<ElementId> wallInserts = wall.FindInserts(true,false,true,true); Solid overallOpeningSolid = null; if (wallInserts.Any()) { foreach (ElementId idinsert in wallInserts) { Element insert = doc.GetElement(idinsert); FamilyInstance famIns = insert as FamilyInstance; XYZ pCutDir = XYZ.Zero; CurveLoop curveLoop = ExporterIFCUtils.GetInstanceCutoutFromWall(doc,wall,famIns,out pCutDir); /// ExporterIFCUtils.ComputeAreaOfCurveLoops( loops ) IList<CurveLoop> profileLoops = new List<CurveLoop>(); profileLoops.Add(curveLoop); if (overallOpeningSolid == null) { Solid negExt = GeometryCreationUtilities.CreateExtrusionGeometry(profileLoops,-pCutDir,1); Solid posExtr = GeometryCreationUtilities.CreateExtrusionGeometry(profileLoops,pCutDir,1); overallOpeningSolid = BooleanOperationsUtils.ExecuteBooleanOperation(negExt,posExtr,BooleanOperationsType.Union); } else if (overallOpeningSolid != null) { Solid negExt = GeometryCreationUtilities.CreateExtrusionGeometry(profileLoops,-pCutDir,1); Solid posExtr = GeometryCreationUtilities.CreateExtrusionGeometry(profileLoops,pCutDir,1); Solid openingSolid = BooleanOperationsUtils.ExecuteBooleanOperation(negExt,posExtr,BooleanOperationsType.Union); overallOpeningSolid = BooleanOperationsUtils.ExecuteBooleanOperation(overallOpeningSolid,openingSolid,BooleanOperationsType.Union); } } } #endregion #region 2.3.2). Create solid from bondary wall face Solid wallFaceExtrus = GeometryCreationUtilities.CreateExtrusionGeometry(planarWallFc.GetEdgesAsCurveLoops(),planarWallFc.FaceNormal,0.1); //make sure the wallFaceExtruded it's surrounding the room (roomSolid is produced by wall faces, so they have same height, although width is variable that's why we intersect both solids) TaskDialog.Show("de",wall.Id.ToString()); wallFaceExtrus = BooleanOperationsUtils.ExecuteBooleanOperation(roomSolid2,wallFaceExtrus,BooleanOperationsType.Intersect); #endregion areas.Add(wallFace.Area); } } } } } } #endregion } } }

I'm attaching the revit project:

Help with this one please, thanks you in advance

Dear Miguel,

I see your pictures and your code, but they do not tell me what the problem is.

Can you be more specific? Otherwise, I have to reverse engineer your code, try to guess what you are trying to achieve, and try to guess what the problem might be. That is a rather laborious and error-prone approach to the issue. 🙂

Thank you.

That said, I did find a rather obscure suggestion to address that particular error under certain circumstances back in 2015:

Maybe not so relevant for your current situation, but who knows?

Cheers

Jeremy
