Hello,

I want to know the license info and API info. I'm still on my investigation stage.

Base on my study, starting from Draftsight professional package onward only allow user to access API

Question 1: May I know if I stopped to subscript/renew Draftsight professional license after 1 years periods, Am I possible remain to use Draftsight Professional without any service pack upgrade or will automatic convert back to Free version?? 

Question 2: 1-year subscription service include what kind of benefit for Draftsight Professional package?

Question 3: I just wondering about the Add-in/Plugin created by using Draftsight Professional. Is that possible Plugin develop by Draftsight Professional able to share to any free draftsight version? Or the Add-In feature will block on free version?

Best regards,
KS Wong
