Adobe Layers?

Posted on 2005-05-12

I am looking at blueprints that are pdf files.  The files were originally created by a CAD program and then "printed" to Adobe.  The author added blue colored hatching in some of the areas of the prints which covers important data.  Is there a way to remove  or hide these blue lines?

I know the data exists under the blue lines because as the image loads, the underlying image is visible first, then the hatch lines load like an overlay on top.

I am currently using the free Adobe Reader.

    Hi Lake,

    You can't edit a PDF file with the Acrobat Reader. If these hatches were added in Acrobat you'll need the full version of Acrobat to remove them, or a program capable to read graphic PDF files, like Illustrator, Photoshop, or CorelDraw. You'll also need to make sure that when these PDF files were created there was no security added to it to prevent such editing. The PDF format includes a security feature where a file can be "locked" so that even if opened in an image editor no part of it can be edited, so you'll need to make sure that's not the case here.
