eDrawing measurement tool for Solidworks Student Edition 2008-2009

Hello,

I recently has Solidworks Student Edition 2008-2009 installed in myPC, and happily completed a 3-D model part in Solidworks. However,when I saved it as eDrawing file, of course with "Okay to measurethis eDrawing file" option checked (enabled), and also "Allowexport to STL..." checked, I am still not able to measure part ineDrawing? Measurement tool is grayed out in eDrawing viewer. Isthere anyone out there having the same problem as mine? If you do,PLEASE help me to solve this problem. I am very appreciate andthanks for the help.SolidworksEducator Student
