What version are you using?

They can either be heavy (old style) or light weight polylines.

For light weight polylines (lwpolyline), when you (entget (car (entsel))) or (entget (ssname sel_set index))) them, there will be multiple dxf code 10's that contain the x and y of each point on the polyline. Each one is a point on the rectangle, so there should be 4 in your case. Hint: the entity data returned by entget is a list.

For heavy polylines, use entnext to step throught the verti until you get to "sequend". Each verti will have its own dxf code 10. I doubt you will need to do this though, if your software is somewhat up to date.

You're welcome.

Yes, lwpolylines strarted before then, so you are probably using them.
