AutoCAD 2008 get Polyline to render flat instead of curved in the corner

[vavalexus]

It's second day I've been trying to solve a problem with rendering of polylines in Autocad 2008, problem that I didn't have at all in Autocad 2006. Read a dozen of topics on Autocad. Can't work further on

The problem is that a flat polyline with length width and thikness parameters (looks as a box) renderes smooth in the corners (looks as a cylinder, or a box with fillets). I need it to render flat as it is! And by some reasons I cannot use solid which render correctly, I need polyline! In Autocad 2006 in render menu there is option "smoothing angle" that just for the such case. 45 degrees by default will do pretty good. But what shell I do in Autocad 2008? There is no such option! It renderes smoothed!

There was a topic on this metter here http://forums.augi.com/showthread.php?t=52371 called "RENDER pline with thickness causes wrong result from 2006 to 2007" but it hasn't been solved.

But they din't find anything then just to advise to work with solids instead of polylines! It won't work at all! Too baaad! Now have to work with 2006 but it is so buggy with materials!
Have another post on materials issue of AutoCad 2006 and below.
