How to make shapes (polygon pour) not visible?

semitech45

How do I make a shape invisible when viewing a PCB design? The shape (polygon pour with a Net) is Etch class. (top or bottom layers)

I use Allegro to view PCB files genrated by others. I need to see some detail that is obscured by the Polygon (Shape). How can I select and then turn off the shape's visibility?

I use Allegro 16.5 Physical view or PCB Editor. (Needless to add, I am very inexperienced in Cadence Allegro.)

Thanks.

    Option 1:  Try to enable OpenGL by going to Setup->User Preferences->Display->Opengl and make sure the "disable_opengl" box is unchecked.  Exit then re-open the board file.

    Option 2:  Select the shape, right-click and select parameters, go to the Shape fill tab, select something other than solid for the "Fill Style", set "Spacing" to a very large value, set "Border Width" to a very small value, then select "Apply/OK".  You should be able to get a shape that just has a thin outline.

    Option 3:  Delete the shape, do your review, then select "Oops/Cancel".

     Good luck.
