stepcode
STEPcode (formerly NIST's STEP Class Library) is used with IFC, STEP, and other standards that utilize the technologies of ISO10303 (STEP). It generates C++ and Python from EXPRESS (10303-11) schemas. The code is capable of reading and writing STEP Part 21 exchange files. It also utilizes Parts 22 and 23 (SDAI and its C++ binding).

Fornjot: A next-generation Code-CAD application
There is also STEPcode [1], which can read and write STEP using C++, it has been kept up to date by the BRL-CAD people and is used by them.
I think modifying Open CASCADE Technology would be a lot easier than starting again.

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.
What are some alternatives?
When comparing stepcode and opencascade.js you can also consider the following projects:
CascadeStudio - A Full Live-Scripted CAD Kernel in the Browser
rust - Empowering everyone to build reliable and efficient software.
