I had an assembly and reference parts for a project A. Now for the project B I copied the assyembly and a few parts (which require changes) to a new folder. Then I renamed the files (assembly and parts in project B). Then I tried to `Replece' the reference of changed parts in Assembly-B using Solidworks Explorer. I selected the previously referenced part (which was from Project A) and clicked `Replace', a dialog box appears, selected the new part and pressed OK.

But the reference part did not change.

After several trials I found that when a referenced document is available, Solidwoks Explorer does not replace the reference. But when there is an error of `file not found' (due to renaming etc.), it replaces the reference successfully.

Any thoughts?
