Here’s a useless SketchUp fact: SketchUp stores coordinates as double , and in inches. Therefor, the maximum physical size of a SketchUp model is 1.7e308 inches, or about 4.3e306 meters. Considering the observable universe is about 4.4e26 meters, a SketchUp model can be about 1e12 (or 1,000,000,00…

[image] Small Radius: Distorted Geometry SketchUp I consulted with David, our resident Computational Geometry expert and long-time member of SketchUp’s development team. He gave me the following answer: Double precision numbers can accurately store ~16 decimal digits. T…

All of which begs the question “why does SketchUp start to have issues with models considerably smaller than the claimed range?”. For example, on a model of an entire city one starts to encounter problems selecting and placing human-size things in the view, as if SketchUp can’t resolve the differen…

@john_drivenupthewall So my math WAS wrong!

Just for fun, I created a cube that is nearly 85 million light years on a side: [image] [image] [image] That’s a volume of 608,213,151,133,022,223,548,903.01542135 cubic light years :slight_smile:

Now try to place another one 1m x1m x1m near it but not on a vertex or edge :flushed:

Ironically, if I started with a 1"x1"x1" un-grouped cube and resized the model setting the length of one edge to 1,000,000,000,000,000,000", I was still able to navigate the model and add/edit geometry with no problem. [image] [image]

I wonder how navigable that model is. I understand that the limitations imposed by OpenGL are significantly lower. BIM application vendors recommend that your model should keep somewhere within about 30 kilometers from the origin (both Archicad that uses OpenGL and Revit that uses DirectX).
