    Default Properties and other hidden information in a dwg file

    Registered forum members do not see this ad.

    Hello,

    I am beginner in Autocad (I have Autocad 2005). I would like to know how can I detect all the information including in a dwg file (like author, signature, copyright, company name). I need to make sure the document is completely neutral before working on it. Please help find the places where to look to make sure my document is neutral.
    Thanks in advance.

    Where did you get this particular drawing file?

    And has this person used a digital signature to sign the drawing?

    What purpose will this drawing be used for?

    How can I know if there is a digital signature? Where do I check this information?
    The purpose of this drawing is to use it as neutral draft for discussion

    I think you aren't being vague enough.

    So you think all this information (like author, signature, copyright, company name) is embedded somehow in the drawing? You're not refering to just what one can see with one's own eyes like in the title block?

    Is the drawing password protected?

    I would think you would know if there was a digital signature attached to the drawing. Anyway you can try the command sigvalidate.

    What everyone is thinking, ReMark is alluding to and I'm gonna ask 'cause I have no manners is - Why should we tell you how to remove information about who spent time and effort creating this drawing? "So it can be used for discussion." Sounds like a synonym (to me) for "So I can turn it in for a grade and not get caught."

    If you need to discuss a poorly done drawing and don't want to incriminate the guilty draftsman, remove the visible identifying information, PDF it and discuss the PDF version.

    If I'm wrong, convince me, I'll happily apologize for my suspicion, and make a few suggestions for what you want to do.

    Glen, Remark,

    I am sorry if I am being unclear or vague. I am total new beginner at Autocad and that's probably why I do not manage to explain myself clearly. I am the middle man between two persons. The first person made the drawing and would like to get a quotation based on the drawing from the second person (so using a pdf won't help as the second person need to have all the dimensions and scale to make the quotation). The first person wants to remain completely confidential. My job is to make sure that there is no trace or connection with the author in the drawing and when I say "trace" I am talking about obvious visible trace. As I am a beginner, I am not sure I know where to look. If it is a Microsoft word file for example, I know I can look in file/properties or in the text itself. But for an Autocad drawing I don't know where to begin. I only see a drawing with no comments.

    I am really sorry for causing all this suspicion
    Wally

    If the person who did the drawing included all the dimensions necessary a PDF file will suffice just fine for preparing an estimate. A copy of the drawing file itself is not required.

    Obvious visible information will be included in the titleblock. Have the originator delete the info before making the PDF file.
