since a few years, I'm drawing as a hobbyist with DraftSight my R/C hulls. today I want to start my installed version 2019, which tells me: out of order, please update. so, I start to update, download 2020 SP3 and install... but now, this will work as a free version? is still a 30 day demo??? have I to export all to a different CAD or is there a documentation to install DS2020 still as hobbyist free version?
