Error when slicing a Solid3D

Hello all,


i am quite new to AutoCAD 2010 .net development using C# and got a problem i can´t understand.

After cutting some Solid3Ds AutoCAD suddenly crashes. Sometimes the "Send Error Report" Dialog opens, sometimes AutoCAD just disappears, sometimes it asks me if i want to save my changes.
Checked everything for memory leaks, looked at the debug output and there are no leaks at all.


Currently i cut along a PlaneSurface that is defined as follows:

            Polyline acPolyline;
            acPolyline = new Polyline();
            acPolyline.AddVertexAt(0, new Point2d(0, 0), 0, 0, 0);
            acPolyline.AddVertexAt(1, new Point2d(-profile.Width, 0), 0, 0, 0);
            acPolyline.AddVertexAt(2, new Point2d(-profile.Width, profile.Height), 0, 0, 0);
            acPolyline.AddVertexAt(3, new Point2d(0, profile.Height), 0, 0, 0);
            acPolyline.Closed = true;
            acPolyline.Normal = profile.Axis.Direction;
            TransformPolyline(ref acPolyline, profile);

            Region acPlaneRegion = GetRegionFromPolyline(acPolyline);
            acPolyline = null;
            acPlaneRegion.TransformBy(Matrix3d.Rotation(Utilities.Math.DegreeToRadian(90), new Vector3d(1, 0, 0), new Point3d(0, 0, 0)));
            //acPlaneRegion.TransformBy(Matrix3d.Rotation(Utilities.Math.DegreeToRadian(-cuttingAngle), new Vector3d(0, 0, 1), new Point3d(0, 0, 0)))

            PlaneSurface acPlaneSurface = new PlaneSurface();


When transmitting the PlaneSurface via the Transaction it looks fine too.

And here is how i cut with the PlaneSurface:

miterCuttingPlanes = GetMiterCuttingPlanes(profile); 

                        acSolidPart1 = acSolid.Slice(miterCuttingPlanes.PlaneCut1Out, true);

                        if (acSolidPart1 != null)
                            if (profile.Cut1Out >= 90)
                                acSlicedSolid = acSolidPart1;
                                acSlicedSolid = acSolid;


 The acSolid is created by simply extruding a region along a path.

As is said before AutoCAD sometimes simply crashes/disappears when executing this. Anyone has any ideas on why this is happening?

It is quite hard to say what might be causing the crash. Can you please share a minimal buildable sample project that I can use to reproduce the error ?


Thank you.
