For me, isometric drawings are better to draw than perspective drawings because in isometric drawings you have to start the drawings with points, and in perspective drawings, you start the drawings by making lines and squares, and I also feel like there is no steps in the perspective drawings, I feel that if you know how to dra perspective drawings, it will take you a long time to learn. A vanishing point is a point in the drawing which erases after the lines are drawn within that point.
