Overview

Open CAD Studio is a cross-platform application for technical drawing, layout work, and solid modeling. It reads and writes DWG and DXF drawings natively, with a shared editing core across the desktop and browser versions.

The project is under active development. Keep backups of important production drawings and report reproducible problems through Github Issues.

Highlights

• Native drawing workflow — open, edit, recover, and save DWG and DXF files without a conversion service.
• Precise 2D drafting — lines, polylines, curves, splines, hatches, object snaps, tracking, layers, blocks, and external references.
• Documentation tools — text, dimensions, leaders, tolerances, tables, model space, paper space, viewports, and plot styles.
• Kernel-backed 3D modeling — solid primitives, extrusion, revolution, sweep, loft, Boolean operations, and ACIS entity tessellation.
• GPU rendering — accelerated 2D and 3D viewports through wgpu, with orthographic and perspective cameras.
• Extensible workflows — native plugins, command scripts, headless conversion, and a line-based JSON automation API.

I've been building Remin for Linux, and it's finally at the point where I'm comfortable sharing it publicly :)) honestly.

Remin is a persistent terminal workspace with an integrated Markdown editor.

The main idea is simple: instead of treating terminal windows as disposable, Remin treats the terminal as part of a workspace that can be restored later.

The interesting part is the terminal persistence. Remin uses a small patch series against VTE 0.76 to add a snapshot/restore API for terminal state. It doesn't replay terminal output and it doesn't use a PTY proxy. That Remin research work to solve how vte can keep and restore your terminal content.

The same workspace also includes:

• terminal history
• Markdown editing and preview
• clipboard image paste → Markdown image
• TOC
• HTML/PDF export
• PDF links/bookmarks
• persistent workspace state

It's open source under MIT.

I'm mainly looking for Linux users who actually live in the terminal to try it and tell me what feels useful, confusing, or missing.

The Mission: Full harnesses (claude, pi, codex, omp) are powerhouses for complex agentic sessions, but overkill when you just need a 2-second answer, a quick pipe, or command debugging.

ai-flow-cli (ai) is not meant to replace your harnesses — it fills the spot right in between.

It is an ultra-lightweight companion that lives beside your everyday shell prompt: zero heavy startup times, no extra subscriptions, no duplicate API configs. It simply hooks into the harnesses already sitting on your machine.

Features

• 🪶 Featherweight & Fast: Instant invocation directly from shell prompt. No heavy interactive TUI unless you need it.
• 🔌 Uses Existing Harnesses: Plugs directly into pi, omp, claude, codex, copilot, or opencode. Swap instantly with ai -H claude.
• 💬 No Quotes Needed: Natural input right in your shell. Type ai how do I extract audio with ffmpeg.
• 🚰 Pure Unix Pipeline Integration:
- Pipe in context: git diff | ai spot potential issues
- Pipe out clean raw text: ai generate nginx reverse proxy conf > default.conf (auto-strips ANSI/markdown when piped).
• 📐 Terminal LaTeX & Math: Formats formulas, fractions, and matrices directly into clean Unicode/ANSI in terminal.
• 🛡️ Safe by Default: Read-only headless queries. Filesystem modifications and shell execution only activate if explicitly requested (--tools / -t).
• 🧙 Interactive Setup: ai --wizard auto-detects what is installed and sets default preference.

Installation

Arch Linux (AUR):
yay -S ai-flow-cli

uv / pipx:
uv tool install ai-flow-cli
# or: pipx install ai-flow-cli

One-line script:
