How could I plot a curve with HPGL command? I know it has an ARC command but my curve is changing its direction very fast and I want that plotter walk on my curve not plotting it segment by segment? could I define an object for the plotter to plotter plot it in one motion?

 

Provided that your curve is given as a set of points, you can use HPGL commands PA or PR to draw a straight line to the next point.
