Diagram Moving

I would like to copy an activity diagram from one project to another project. Is there any way to do this? The normal cut and paste doesn’t appear to work.

Currently, we don’t provide this feature. Becuase the model cannot copy.

I have a small question on rearranging the usecase diagrams
is it possible to rearrange the usecase diagram in our desired order instead of creation order
if I create usecase1, usecase2, usecase3 one after another, the order displayed on Diagram Tree and output reports( pdf files) are usecase1, usecase2, usecase3

is it possible to rearrange it in order of usecase2, useacase3, usecase1 in the diagram tree and the output reports(pdf files)
