Reduce file size after deleting elements

Hi everyone,

I'm trying to reduce the file size of a DGN file that contains the city of Toronto. I need to create smaller separate files in order to import them in another software. I was able to delete elements and keep only a small fraction of the model but the filesize stills the same...

Could you help me?

Thank you!

  • Lorys, I think talking about the cost of storage is going a little off subject here.

    What Phil says is correct in that once you delete elements in a design file they are not marked as deleted but are immediately removed which should reduce the file size straight away.

    Compressing the file will get rid of any unnecessary details within a file but only if this information is no longer required.

    I think the better option would be to reduce the file size by extracting only the required detail out to a separate file using the FENCE FILE command.

    FENCE FILE (FF=)

    Used to copy the contents of a fence to a new DGN file.

    Using a Key-in to Copy the Contents of a Fence to a New DGN File

    1. In the Key-in window, key in FENCE FILE or FF=.
    2. The Save Fence Contents As dialog opens.
    3. Key in the name of the new file and set the directory in which it is to be created.
    4. Click OK.
    5. Accept the copy.

    Not really as Gerad made the  following statement  and I was responding to it not the  original post.

    quote "...... it is probably one of the huge perpetual sources of income for the digital storage hardware industry "

    Plus I enjoyed showing the contrast between the technology costs  from less than 25 years ago... most youngens  have no idea of what it was like for us users in late 80's

    We needed to compress whole network ( clix/ unix)  directories daily to stop IT departments moving folders around to make more room .. in my instance messing up reference  paths....

  • Might be best if you are responding to queries that are off topic to send a private message. This may be interesting to some people but the post was placed in the MicroStation forums to answer specific questions.
