Dear Forum user,

Hello! MicroStation Mouse here with an answer:

There is no way I've heard of to password protect individual levels. You
either don't let people edit the file, ie write protect it or you do let
them edit it. The lock option is there so if there is a level you don't want
people to mess with, the fact that it is locked should communicate that fact
to them. But it only works when all are in agreement with honoring this
philosophy.

There are ways within a controlled MicroStation V8 workspace to prevent
people from changing level table assignments (lock for example) but that
requires you to control the workspace and to control the user's requirement
to use a particular workspace. From your question I'm guessing that is not
going to work here.

My suggestion would be to use either design history or a product like
Axiom's DGNCompare to compare design files at different stages of
development to see what has been added, deleted or modified since the time
you locked the level. It won't prevent others from making changes but it
will give you a way to see what's been changed.

Let me know if this is helpful.

All the best,

MicroStation Mouse :D
