I am the sole user of DraftSight, and I plan to use the software both at the office and at home.

1. Do I need to purchase a DraftSight Enterprise - Network License?

2. If I purchase one DraftSight Enterprise - Network License, can I install it on multiple devices and use it on one device at a time? 

3. If the DraftSight Enterprise license server is set up on an internal company computer, can I still launch and use the software while off-site and not connected to the company network?
Thank you !
