I'm a new member, I have a issue and need your help:
I'm working on drawing1.dwg. And I want that when user switch out to other drawing (drawing2.dwg) or create a new drawing,
application will show "yes/no" option for user.
If Yes, drawing2.dwg will be activated.
If No, keep working on drawing1.dwg.
Please tell me, how can I do?
