We are having this issue that every so often the software keeps change in the Fonts of the drawings. I've result on reinstalling the software everytime it happens. An Observation is that this is happening with computers that have Autodesk and Bentley products installed. The last person that had the font problem happened after a Autodesk Update.
I'll try this and let you know the Outcome. thank you.
WE are using FDOT tools only for Bentley products. Autodesk (Civil 3D) runs as is. We installed a Patch for FDOTSS10 and it solve the issue for our two users.
