how to open the file?
Hi gars gars,
Thanks for your post.
If MicroStation outputs a message "not a design file", then it likely indicates the file is not readable by MicroStation.The most common design file types are .dgn and .dwg.In Windows File Explorer, open View tab > Toggle ON File Name Extensions. What is the file type (i.e. .dgn, .dwg, .docx, .xlsx, etc.) of the file you are attempting to open?This old Wiki might be worth looking into, however, it is pertaining to an older MicroStation version.https://communities.bentley.com/products/microstation/w/microstation__wiki/15417/v7-error-message-unable-to-open-not-a-design-file-after-opening-in-microstation-v8
Lastly, can you specify the version number of MicroStation you are using?
