How to detach from central for only select worksets?

[Sleepingfish_Kuo]

I've select only the worksets I want to keep, but the detach file still keeps anything.

They are two different settings and have nothing to do with each other.

So I need to do it manually like this?

1. detach with workset keeps.

2. delete all things in other workset.

3. save.

4. create detach file again (throw the workset) and save.

No. Here is what you do:

- close the file

- open it detached

- delete worksets (not elements) you do not want

- revit will give you two options, pick the obvious one

- save the file
