Thanks for the fast reply! I didn't know I had to use the ctrl key.
1) Selecting vertices works!
2) Join works
3) ctrl + A works
4) ctrl + d also works fine.
These functions work well, but I think i need a deep tutorial for using all functions of the app.
It looks more powerful than picocad but I can't understand how to do basic things like rotating the view, or coloring a single face and not the whole object.
Is there a tutorial or documentation I can read to understand how to make the most out of pelogen?
Thanks again.
(By the way i'm on a MacOs 12.5 MacBook Air)
