Thanks Kristoff
Yes, I was pleased to see my stones being used in your stone buttress. It is hard work packing them by hand (in the real and virtual worlds). Our first software release will be for packing polygons into a rectangular area so suitable for simple paving jobs. We will have something to build a stone buttress like in the photo on your other post but it will be more than a year away. I think you signed up for our newsletter so keep your eye on it.
I haven't been a regular user of these forums but as we start to produce something worth sharing, and hopefully a Sketchup plugin, you might see me here more often
