Draw Polylines

I wanted to draw polyline,But when I press* enter* or press left button of mouse the polylines don’t exist! How can I solve this?

Are you sure it doesn’t exist or are you just not seeing it? If you make a polyline and then type SelLast, does what you just made show up as highlighted? If yes, check to see if you are in rendered mode - curves don’t show up in default rendered mode. Try putting your display into wireframe to see if they show up.

If the curves are actually not getting drawn, there may be a different problem. What version of Rhino are you using?

Thanks a lot. It was in rendered mode. Now I can see. I m using Rhino 4.
