How to use one file’s Dimension setting to others, so the user does not need to set Dimension style in other file again?

A: The feature of Dimension export and import will make you convenient to do this work. If you have already set the dimension parameter in current file, please export the setting as a file using Express>Dimension>Dimstyle Export and save it in your pc. So you can remain the dimension style, after that it could be referenced to other files using Dimstyle>Import. It will save your time much more.
