AutoCAD Civil 3D

[#1]

I have Autocad Civil 3d 2011 and recently the software was corrupted so our IT guy reinstalled everything. Now when I attempt to attach a PDF I get an error box that reads

     This file cannot be opened.

-------------------------------------------------------------------------------

     The problem can be caused by several things:

     -  The data in the file is corrupted

     -   The file is an earlier format that is no longer supported

     -   The file format is not supported

     Try to obtain a better copy of the file, recreate the file using

     different settings, or convert the file to a supported file format.

--------------------------------------------------------------------------------

Now before the reinstall, I never had an issue...never saw this message before and have attached hundreds of PDFs to drawing. The only thing I will add is around the time of the reinstall, I also had installed NITRO PDF software. I believe this installation came after the problems started...just cant remember, so I wanted to throw that out just in case.

Our authorized dealer didnt have any answers and even contacted Autodesk and didnt have any answers....other then do a repair reinstall.

Thanks,

Randy

Maybe it has something to do with the PDFs that are being created by Nitro PDF. Do other computers in your office work? Try referencing the attached PDF.

Jeff,

I tried your PDF and got the same error. The Nitro PDF I am using, I have not created any files using it...just modified previously made PDFs done by others.

Thanks,

I've found that converting PDF's to tif's make working with them easier.

But that's me :-)

You are correct, TIFFs are easier to work with...especially if you need to use an older version of Autocad that doesnt support PDFS. But, for me if I open a project from someone else and there are 15 details that are PDFs...it is a waste of time for me to have to convert them all...reattach them...fit them to the page..then print.

thanks,

Randy

Have you tried the repair/reinstall? That may be your best bet.

I gather you have all the updates and patches fow C3d and Windows as well? Also just for fun amke sure you have the latest adobe reader. Ratehr than Nitro, try PDFILL. Its free and awsome.
