I’m 78 and have been a SU user since V1.0 when it was a startup by some guys in Colorado. I now work with SU 2023 Studio. For the first decade or so, I didn’t really use it seriously, but loved it anyway. In the last 12 years, I’ve been very active using it as a hobbyist drawing structures and machines for my 1:48 scale model railroad and have uploaded a number of these models to the warehouse. I am also producing highly detailed engineering models of US Naval weaponry that are being permanently displayed in the USS New Jersey Battleship Museum. I use the SU output either to create laser cutting templates (through Coreldraw) or creating exported STL files for 3D printing on my own resin SLA 3D printer. I’m a Mac user.
