i know Route->Gross->add fillet is used to add teardrops.
But how to get the first type? I can only get the second one.
I think if I remember correctly this feature changed so that now the fillets are always shape based to improve the quality of the fillet. I beleive this happened about the 16.3 release. You can change the shape form by adjusting the settings in Route - Gloss - Fillet Parameters (for OrCAD) and Route - Gloss - Parameters - Fillet and Tapered Trace (for Allegro) which might give you the shape you require.
