editing shapefiles, changing them

[Michal Krupička]

Hi all,
 I am not sure, if this conference is the right place for my question.
The problem: I have shapefile with some objects, but they were made in bad
resolution. It was my fault during digitalization. But now when the shapefile
is created i need to change its resolution. I need to raise all object five
times and save it back to shapefile. This problem appears in scalebar, where
the wrong values are now.
Thanks Mike
