<DIV>As my screen capture shows, I am able to select the Layer or Project or
Ellipsoid CRS. I am able to do it on a “Line” “Point” and “Polygon” Shapefile
(.shp) file. I’m running QGIS 1.8 Lisboa. Maybe check and make sure that you
have the most up-to-date version. Apart from that I’m not sure what else to tell
you. Hopefully someone else can help.</DIV>

point one is solved but for point two, export/add geometry tool returns the
window as attached, there is no option for choosing CRS for area
calculation.<BR><BR>Regards<BR><BR>

You need to uncheck the "Toggle Editing" and "save" your layer and then it
will be displayed with the proper width and precision that you set it
to.<BR><BR><BR>2<BR>Further I read in new functionality list of QGIS1.8 that
area/length etc.<BR>may be calculated by using project (if in metric units)
CRS in QGIS 1.8,<BR>without changing original CRS of layer if it is in
Geographic coordinates.<BR>Is this feature available in
1.8?<BR><BR>ANSWER2--- It does give you the option that when you use
"Export/Add Geometry Column" that it gives you the option to Calculate using
Layer CRS, Project CRS, or Ellipsoid. You can save to a new layer or update
the current one which your using. I have not experimented with this in
different projections to verify the accurate data or the area/length but the
"plugin" does work.<BR><BR>Regards<BR><BR>OS-Windows7, QGIS 1.8 stand alone<BR
