lineweight problem with directx device in dd 2.5.2
hello,
this is a known problem. directx device uses 32bit float calculations, instead double (as in wingdi). coordinates of lines in attached drawing lies in 30000 - 35000 range, in this case precision in float calculations lost. the smaller the coordinates of objects in the drawing, the lower the distortion of objects as result of conversion from double to float.
