Attach a PDF as an underlay

Lots of people use the PDF format. If you have a PDF image that you want to reference as you draw, you an attach it as an underlay, starting with AutoCAD 2010. This is similar to attaching an xref.

Choose Insert tab> Reference panel> Attach (the ATTACH command). You can also use the PDFATTACH command.

In the Select Reference File dialog box, choose a PDF file and click Open.

In the Attach PDF Underlay dialog box, if the PDF contains more than one page, choose the page you want to attach.

Choose the settings you want for the insertion point, scale, and rotation. These settings are just like attaching any xref.

Click OK to attach the PDF underlay.

You can snap to object snaps on the border of the underlay. For example, the corners are endpoints.

    It is very great tip, but I am in question how to fine tune of the word or else document of PDF to real scale factor of the AutoCAD drawing.

    Can you comment for my another question? How can we copies all files associated with a drawing in the AutoCAD 2006/2008/2009/2010? In AutoCAD 2000 we used PACK command under Express > Tools > Pack ‘n Go.

    Excellent, but I have a question: How can I see the rest of the pages in a multipage PDF file when I insert it as xref?. Thank you.

  • Ellen

    If you attach the PDF at a scale of 1, it should be OK. I created a PDF of a 3×3 square and inserted it and it was 3×3 in my drawing.
    For putting together files, use ETRANSMIT.

    Just tried this. When you attach a multi-page PDF, you’re prompted to select the pages you want to insert, then prompted individually for an insertion point and scale for each page. At least, that’s what happens when I do it in AutoCAD 2012. I’d never tried this before, so thanks for that question!

    AMAZING.BUT CANN I HAVE REPLY FOR MY QUESTION BELOW:
    HOW I CANDOING MODIFICATIONS FOR THIS INSERTED PDF FILE,I MEAN IF I HAVE AN PDF DRAWING AND I NEED TO MODIFY OR UPDATE THIS DRAWING ON AUTOCAD SCREEN AND I JUST HAVE THIS DRAWING IN PDF FORMAT, SO I THOUGHT WHEN I WANT TO UPDATE THIS DRAWING I WILL GOING TO INSERT IT ON AUTOCAD SCREEN BECUASE WHEN INSERT THIS FILE MOSTLY I HAVE GOT LIKE A JPG. THANK YOU

  • I INSERTED A PDF AND A DWG FROM MASTERCAM INTO A DWG THAT I WAS WORKING ON.. I SENT IT TO THE PERSON THAT SENT THE MASTER CAM DWG AND TO ANOTHER TO OPEN, BUT IT WILL NOT OPEN.

    I REMOVED ALL THE PDF AND THE MASTER CAM DWG, IT WILL NOT OPEN WHEN SENT.
    I COPIED ALL OF MY WORK TO A NEW DWG FILE. BUT IT STILL CANNOT BE OPENED BY OTHERS.

    IT SEEMS TO HAVE INFILTERATED THE WHOLE DWG.

  • Ellen

    First, test another drawing to see if it’s really the drawing.
    Then, try the WBLOCK to create a new drawing and see if people can open that.
    The PDF may have some restrictions that corrupted the drawing.

    MOHD:

    You CANNOT change it unless you draw around all the lines, so effectively you have made a copy & then scale it to the correct size.

    OR

    Purchase a “PDF to DXF converter” – bear in mind that this will only work on pdf’s which are not password protected.
