[V8i | CONNECT] Why does this DGN show level is used?

There are two levels in the attached DGN, the default level and "DR 066 Dirt Road". The level manager will not let me delete the DR level and displays the "level is used. Use command level usage...". Level usage shows:

I also tried to use the "select by attributes" command to try and select all elements on this level with no success (finds text with no characters and un-displayed text nodes etc.).

NOTE: If the DGN is compressed the level can be deleted. I am posting this msg because this issue exists in multiple files and is causing problems with another process down stream and I need to find the cause.LevelProblem.dgn

  • The elephant in the room is that the Levels Used command does NOT list all the places where the level is used, i.e. in this instance, LineStyles. Probably also MultiLineStyles, and so on.
    I'll report this as a Feature Request.

    FWIW. MotCurve and MotDIrection are the 2 Linestyles in the DGN that are made from the Dirt Road levels. You can COMPRESS just the Linestyles, but, lobgnger term, I'd suggest rebuilding these using Default level.
