Using Autocad 2011 (full version), Acroplot Pro & Acrobat X Pro.
Certain circles & less often lines and/or text wont show up on the pdf.
It only happens when batch plotting from Acroplot to pdf. If I plot from Autocad straight to Acrobat X all lines show up just fine.
I had the same problem when using an earlier version of Acrobat & I fixed it by unchecking the "optimize pdf" box & iot worked fine.
Now that I've upgraded to Acrobat X the problem is back & I also can't find the "optimize pdf" box.
Any help would be appreciated.
