Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Is there a tutorial for making a CAD tool with Three.js?
For proper CAD in browser, you'd need something like opencascadejs. I've integrated it to Polygonjs, here is an example scene, and a video intro

CadQuery –- A Python parametric CAD scripting framework based on OCCT
That confirms the impression I had, I guess they are just so complex that building a new open source one from scratch would be Herculean effort. Guess OCCT is the only option for now.
The itch I would love to scratch is an online real-time collaborative parametric cad app using CRTDs. Current thinking is combining OpenCascade compiled to WASM [0] with Yjs[1], but frankly don’t have the time.

Hey Rustaceans! Got an easy question? Ask here (45/2021)!
Can I access a library that is compiled to WASM (e.g. openCascade.js) directly from a rust client web app that runs in the browser? The library is lgpl so I'd want to "dynamically link" to it.

CadQuery –- A Python parametric CAD scripting framework based on OCCT
See this github issue for example: https://github.com/dcowden/cadquery/issues/29
- the UI (cq-editor) is unusable for real-world work: no perspective rendering, no graduations in ortho views, no way to measure things on the object, no way to examine the BREP, etc ... Generally speaking, the UI is only a visualizer, and does not let you query / inspect the model in any detailed way.
