Intersect and Union sometimes produce incorrect result for ellipses

Solución alternativa

1. PairwiseIntersect with MaintainCurveSegments = True. Refer to https://pro.arcgis.com/en/pro-app/latest/tool-reference/analysis/how-pairwise-intersect-works.htm
2. If maintaining ellipses is not critical, convert the Shapes feature class to a shapefile to remove curves and use the shapefile as input.
