My 'first day at school' on the forum today.
I'm an intermediate level developer specialising in historic WW2 airfields. I use Sketchup with Marginal's exporter plug in, Photoshop and GIMP. Wouldn't consider myself expert in any of these but able to produce a reasonable looking airfield.
To be upfront, touchy moderators on another forum ended my tenure there so exploring pastures new!
Onward and upward!
