After verification, using the explodeintolinesandarcs method in the dxflwpolyline object, the graph is reversed my code: DxfLwPolyline oPolyline = (DxfLwPolyline)item; GraphicsConfig graphicsConfig = new GraphicsConfig(); Polygon2D[] polygon2DArray = (Polygon2D[])oPolyline.GetClipBoundary(graphicsConfig); or List<DxfEntity> lstEntity = (List<DxfEntity>)oPolyline.ExplodeIntoLinesAndArcs() The output graph is wrong!

Hi, This was indeed a bug, it will be fixed in a next release. Thank you for the report! - Wout
