AutoCAD 2010/2011/2012 DWG Format

[#1]

I am currently teaching AutoCAD 2012 at our community college. In going thru our textbook, I have run into a couple of commands that don't seem to be working correctly.  I have used the REVERSE command on a polyline with width, and the command line says that it was reversed, but the polyline remains the same visually - no change.  Also, today I was demonstrating the BOUNDARY command, and even though the "Detect Islands" is checked, it does not detect the islands when creating a boundary.  We are currently using AutoCAD 2012 SP2.   I know it worked in the 2011 version as well as the REVERSE command as I taught it last year.  Not sure what is going on here.  Anyone with any ideas?

Is the problem with BOUNDARY command in one DWG file, or all DWG files?

Is the entire outline visible on screen?

Judith,

Reverse:  I don't think there should be any appearance change unless a directional linetype is used.  To reverse the appearance, you might need to use mirror.

Boundary:  Post a drawing that exhibits the problem and indicate your pick point.

I had not tried another drawing as it was the same drawing that I had used last year when teaching the 2011 version. It already had an existing polyline drawn with 6 islands in the center. All polylines are closed - I checked the properties of each to make sure they were. If it worked last year with this same drawing with AutoCAD 2011, there should be no reason why it should not work in AutoCAD 2012? Did Autodesk by chance change anything about the behavior of this command? Judith Marcum

Post the DWG and let's have a look: nothing has changed AFAIK.
