plot window area
can someone please explain to me how the plot window area coordinates are calculated? i use the two methods below to set and retrieve these values, but i'm uncertain of how to set these for modelspace.
playout->getplotwindowarea(xmin, ymin, xmax, ymax);
pvalidator->setplotwindowarea(playout, xmin, ymin, xmax, ymax);
when i select a plot window area in paperspace and save the drawing in autocad, the values match the drawing coordinates, which i can see in the status bar as i move the mouse. when i perform this same step for modelspace and save the drawing in autocad, i'm not able to determine how these numbers were calculated, since they don't match the drawing coordinates.
thanks in advance.
