Hi @the phoenix,
Thanks for posting in the Lucid Community!
First I want to clarify, when you attempted to export your document into Visio, did you follow these steps below, also listed in our Export or print a Lucid document help center article?
Visio file 
To export a document as Visio file you must be on an Individual, Team, or Enterprise account.
To complete the export, follow these steps:
- Open
the More menu from the top-left of the canvas. - Hover your cursor over “Export”.
- Select Visio (VSDX) or Visio 2010 (VDX).
The file will download to your local device.
Note: The only action type supported in Visio after VSDX and VDX export is a link to web. VSDX and VDX action types not supported include linking to a page, layer, document, or email.
Will you please try the following troubleshooting steps so I can take a closer look at the issue you’re experiencing:
Please let me know if you are still experiencing the issue after trying the steps above and I am happy to jump in and take a closer look! Thanks in advance for your help and patience!
