Drawing a Sketchup model of this park sculpture seemed like a good modeling exercise, but its proving to be more difficult than I had anticipated.
The layout is pretty straight forward. With three radius points located in space all that’s needed is the angle departure from the main axis to determine the start and end points of the sculpture. When I try to take it up into three dimensions, however, that’s when all the geometry gets muddy. There must be a way isolate the various segments of the structure so that when they’re pulled up into three dimensions they don’t distort other forms.
