Dave is a Dublin Builder who shoots from the hip and is a dab hand at SketchUp. He likes to share his knowledge as well as his many opinions on a diverse range of topics. Here he generally just talks about the headline topic, though he does tend to wander a little from time to time.
So even if you know SketchUp backwards, you maybe should still take a look at this presentation. Dave has a unique style.
