Cannot Detach a model from managed model

Hi Ryan,

Could you please upload the dgn file together with any of the reference files you can not detach for testing purpose?
I have installed MicroStation 08.11.09.714 and I can not reproduce the issue.

Maria

Take a look at the wiki below for the answer to your question:

The solution posted may work but it isn’t practical. I shouldn’t have to load Openroads in order to detach a simple dgn file that wasn’t attached through Openroads. I should be able to do it through Microstation. Furthermore, if I have to open the file with Openroads, it says there’s obsolete civil data found and asks to upgrade the data.

When detaching a dgn, Microstation should have the capability to tell whether or not there’s civil data dependencies or not. If there is civil data dependencies, then a warning message makes sense, but not if there’s no civil data dependencies. To disable detaching a reference from basic Microstation whether or not there’s civil data dependencies is not acceptable.
