Hello, Unfortunately copying the use case diagram to another project is not possible in SCADE Architect. Because the UCD diagram contains referenced use cases of other state machines and activity diagrams and actors. Since these references are not copied together with the use case, SCADE architect does not allow this.  However, if you want to copy the whole package, SCADE Architect will allow it. 

Hope this helps!
