Technical Drawing Models

👉 Interactive viewer: https://numberformat.github.io/SCADTechnicalDrawingModels/

This is a collection of exercises that are commonly used when learning technical drawing.

This collection was put together more for Nostalgia. Many of us learned to draw using these objects.

What this repo contains

  • src/models/ — OpenSCAD source files (top-level only)
  • src/assets/ — Pre-built assets (top-level only)
  • src/images/ — Optional user images (any format, converted to PNG)
  • site/ — Generated viewer output (build artifact)

Build

macOS / Linux (bash):

./pipeline.sh build

Windows (PowerShell 7+):

.\pipeline.ps1 build

Viewer

Run the local viewer:

./pipeline.sh run

.\pipeline.ps1 run

Upload to Github and enable Pages

Enable GitHub Pages to publish the viewer:

Optional (guided, console-only auth supported):

./pipeline.sh create-github

.\pipeline.ps1 create-github

The setup will initialize a git repo if needed, commit your current files, and ask how to handle any existing origin remote.

If GitHub Actions is disabled in the new repo, enable it here:

https://github.com/<owner>/<repo>/settings/actions

After GitHub Actions publishes the gh-pages branch, enable Pages here:

https://github.com/<owner>/<repo>/settings/pages

Token scope guidance (classic PAT): - public repos only: public_repo - private repos: repo - org repos: admin:org Avoid delete_repo and project unless you explicitly need them.

Optional (guided):

./pipeline.sh create-github

.\pipeline.ps1 create-github
  1. Go to Settings → Pages
  2. Source: Deploy from a Branch
  3. Select gh-pages and / (root)
  4. Save and wait for the site to publish

The viewer includes: - Image browser with thumbnails and 3D toggle (for STL previews) - README and LICENSE tabs (rendered into the page during build) - Build date shown under the page title

Releases

Each build on main publishes STL assets as a GitHub Release.

Pipeline

This project uses the SCADPipeline build system. See the pipeline README for details and updates: SCADPipeline README.
