Hai Dear all
I am using Autocad 2007 i re installed my autocad.
when i am trying to plot -for the plott area using window i can select any points.but if i want to change the pick points .its not getting mean to say.the selected area in black and other area gets gray colour.i cannot secet from the outside of the first selection,that area cross hair also not show.
please help me..
 but i can select or reselect from papaer space.

You're trying to plot from model space or from a paper space layout?

I could be reading your problem incorrectly, but it sounds to me like you're trying to pick points within your viewport. Try typing [CMD]PSPACE[/CMD] before you plot.Does this help?
