Measurement tool

I have a couple of questions about making "measurements" on AutoCad drawings?  We have recently converted to SolidWorks 2011 and no longer have access to our AutoCad application, but we have a raft of lagacy AutoCad files.  We have often used AutoCad's "measurement" tool to make or confirm dimensional measurments.  While the free eDrawings shows the measurement tool, it is not accessible.  Question 1: Is the measurement tool available only on the upgraded eDrawings, which is not free?  Question 2: Does the Draftsight application offer a "measurement" tool?  We can open our .dwg files in SolidWorks but the conversion process takes a little time and is cumbersome for just making measurements.  We think it would be more convenient to use an eDrawing version (free one, of course) or Draftsight that allows the function.

Thanks,

Dick
