Object selected is not a polyline
Do you want to turn it into one? <Y>

This is a prompt that we have all seen thousands of times.  It shows up every time that you select an object with the PEDIT command that is not a polyline.  Personally, I have always wondered why AutoCAD is asking me this.  If I didn’t want the object to be a polyline then I wouldn’t have used the PEDIT command!  Don’t get me wrong I’m all for being careful and I believe in the philosophy of “measure twice, cut once” but this is ridiculous.  We are treating the conversion of an object to a polyline with redundancy similar to using two separate keys to unlock the launch sequence of a nuclear missile. 

Ok, maybe I’m getting a bit carried away, but if you are trying to be more productive and save as many keystrokes as possible, then this seems like an obvious candidate to be fixed.  And with the introduction of AutoCAD 2004 Autodesk has finally done just that by adding a new system variable, PEDITACCEPT.  Just type PEDITACCEPT at the command line and set the value to 1.  Now you will never be asked that question “Object selected is not a polyline Do you want to turn it into one? <Y>” again.
