That is exactly what AutoCAD does when you use the command RECTANG;
If your question is: How to draw a polyline? It should be already answered in other threads.
If you have trouble getting YOUR code to work, come back here, post your code and explain the desired behavior.
P.S. Hold on, did he just say AutoCAD Electrical? Does it use the same API as AutoCAD?
