Loosing Lines in view

[John30168806gijr]

This has just started happening. Running on a mac....

Seems to be loosing line in all PDF files.... 

 First image when open document....

 Should be like this, this only shows when I use the pan.

Hi John30168806gijr,

Thank you for reaching out.

Please let us know if this happens with particular PDFs. Would you mind sharing the files with us?

Share the Acrobat and OS version numbers.

Did you make any changes recently that may have caused this?

Does the line disappear after you open the PDFs, or are they opening like this (as in the screenshot) now? 

What do you mean by "when I use the pan"? Please explain.

Thanks,

Meenakshi

Here is the PDF, printed from AutoCAD.

Also OS and Acrobat ver

No changes to Acrobat or the PDF.

Opens like in Screen shot but when I use the HAND TOOL it regens all the lines.

Thanks,

john
