You created the Seattle Park lesson?
It is very well done and a great learning tool.
I usually get up at around 4 in the morning and work on that lesson with my dog at my side giving me encouragement before I head out to work.
I am a landscape designer and use LandFX which is also a great program. I love how the two programs interact with each other. My goal is to get proficient in SketchUp as the little bit of rendering that I have done with SketchUp really helps my clients understand what all the circles and squiggly lines in my 2-D designs really represent. However, I am self teaching the program so progress can get a bit bogged down as in Montrose CO, there aren’t any formal classes offered.
So, thank you for being there to help me when I get stumped.
