This information was very good, thank you Dennis.
Okay for myself and my children, if I can improve myself on this subject, I want to teach my children( 7 and 9). I think it would be healthier for them to draw instead of games for fun on their phone or pc. We come to this world individually, time is very precious. they loved sketchup and as far as i understand they are having fun and i plan to teach onshape.
I want to put some emphasis on sketchup and onshape these days.
