Brainstorming some ways to visualize the hierarchy effectively and thought I'd share some progress. It's not fully explored, but the general idea is a small 2-level hierarchy infographic that shows the object in question, it's top N subassemblies (based on volume), and associated object counts.

I wonder how close of an approximation I'd get if we run analyze on all primitives to get their volume (which is fast) and then apply a basic heuristic perhaps based on bounding box overlap, to estimate booleans on the volume. Could possibly give a really fast / instantaneous volume approximation that'd be better than simply summing up the individual volumes. gqa takes seconds or minutes, so having something that gives a fast rough answer could be super useful for some things. I wonder what that error bars look like...

I'm working with a team of students this semester that are working on making a tool to automatically generate a single page summaries of geometry. The design's starting to solidify, so I thought it'd be great to good to share a preview of one of the design sketches for feedback and discussion: image.png

The general utility is this will make it really easy to index and catalog a repository of models, and to share what's essentially a geometry v&v tech sheet for those models. That is, a way to share details about a model (textually, graphically, and contextually) without necessarily sharing the model itself and/or having to open it up in a GUI, etc.
