Screen update become slow when using GetSplitCurve() with DBObject.HangOverTo()

Good evening everyone. I have a question.

I have below code to split an original curve into 2 new curves then hangover 1 of them with original curve.

Point3dCollection splitPnts = new Point3dCollection(); splitPnts.Add(trimPnt); using (DBObjectCollection splitCurvs = memCurv.GetSplitCurves(splitPnts)) { //baseEd.WriteMessage($"\nSplit curves 's number : {splitCurvs.Count}"); //baseEd.WriteMessage($"\nSplit curves 's point : X = {splitPnts[0].X} , Y = {splitPnts[0].Y}"); //Find closet points : Point3d cloPnt1 = ((Curve)splitCurvs[0]).GetClosestPointTo(stdPnt, false); Point3d cloPnt2 = ((Curve)splitCurvs[1]).GetClosestPointTo(stdPnt, false); if (cloPnt1.DistanceTo(trimPnt) <= KRTolerance) memCurv.HandOverTo(splitCurvs[1], true, true); else memCurv.HandOverTo(splitCurvs[0], true, true); }

The problem is after the command is finish , the original curve is still the same and i have to drag my mouse about 1～2 seconds for screen update .

I tried to use Autodesk.AutoCAD.Internal.Utils.SetFocusToDwgView();

But it didn't work . Please help .

Thanks in advance !

Is it possible to see your code in its entirety?

Hi , It is ok . I sent it as below .

Now , i also put my alternative way to achieve this , but actually i want to finish in the old way with screen update not become slow.

void CmdTE_TrimCurves(Editor baseEd, Transaction baseTr, Curve boCurv, Curve memCurv, Point3dCollection intPnts, Point3d stdPnt) { //Variable for trim point : Point3d trimPnt; //Upgrate member curve to 'OpenForWrite' memCurv.UpgradeOpen(); trimPnt = intPnts[0]; //Find point to trim : if (intPnts.Count > 1) { for (int i = 1; i < intPnts.Count; i++) { if (stdPnt.DistanceTo(intPnts[i]) < stdPnt.DistanceTo(trimPnt)) trimPnt = intPnts[i]; } } #region [Trim curve] try { Point3dCollection splitPnts = new Point3dCollection() { trimPnt }; using (DBObjectCollection splitCurvs = memCurv.GetSplitCurves(splitPnts)) { //Find closet points : Point3d cloPnt = ((Curve)splitCurvs[0]).GetClosestPointTo(stdPnt, false); #region [codes part that seem to make process became slow] ////Trim curve : //if (cloPnt.DistanceTo(trimPnt) <= KRTolerance) // memCurv.HandOverTo(splitCurvs[1], true, true); //else // memCurv.HandOverTo(splitCurvs[0], true, true); #endregion #region [My alternative solution for now] Curve retCurv; if (cloPnt.DistanceTo(trimPnt) <= KRTolerance) retCurv = (Curve)splitCurvs[1]; else retCurv = (Curve)splitCurvs[0]; ObjectId retId; using (Transaction tr = db().TransactionManager.StartTransaction()) { retId = AppendEnt(tr, retCurv); tr.Commit(); } memCurv.SwapIdWith(retId, true, true); memCurv.Erase(); #endregion } } catch (System.Exception ex) { ed.WriteMessage($"\nError : {ex.Message}"); return; } #endregion }

Thanks in advance !
