I have feature class with polylines. I need to intersect the circle polygon.

ITopologicalOperator3 topOperator = (ITopologicalOperator3)pPoly;
topOperator.IsKnownSimple_2 = false;
topOperator.Simplify();
IGeometry resultGeom = topOperator.Intersect(polyline2, esriGeometryDimension.esriGeometry1Dimension);

it gives me result in complete different place.

input output:

which of the two geometries is `pPoly` and which is `polyline2`? – MakePeaceGreatAgain Dec 19 '19 at 11:28
pPoly is circle polygon, polyline2 line. – aybb_2000 Dec 19 '19 at 11:51
And what output do you expect? – MakePeaceGreatAgain Dec 19 '19 at 12:14
I have a feature class with polylines in it. i need to have the polylines that are inside the polygon that intersects. – aybb_2000 Dec 20 '19 at 10:41
you mean that the result lays at totally different coordinates, away from the original line? – Malior Apr 01 '20 at 08:34
