Converting the first vertex of polyline lines to points with starting line angle

I need to extract the starting vertex only and the line direction (angle). The polylines also have arcs in them but I only need the first vertex and starting line angle in the output. I will use this information to insert an arrow head pointing at the point with the back of the arrow or wide end in-line with the polyline. My source data is in a ARCGIS application with a SQL database and I’m converting that information into AutoCAD. So, the arrow head will be a block pointing at the first vertex with the back end in-line with the polyline. Basically, I need to insert flow arrows but in CAD. I can do it in ARCGIS without any issues but I need to get the same symbology into plain cad without a geometric network defined. I tried several transformers i.e. the chopper but it converts arc’s into line segments and inserts multiple points. Any help would be greatly appreciated. Example of the finial output attached.
