Show HN: LuaCAD – Parametric CAD Scripted in Lua
TL;DR
LuaCAD is a new scriptable CAD tool that allows users to create parametric 2D and 3D models using Lua. It supports multiple export formats and offers a syntax similar to OpenSCAD, enhancing usability for CAD developers.
✦ Why It Matters
Start using LuaCAD today to enhance your CAD modeling with scripting capabilities.
Key Takeaways
- Install LuaCAD via cargo for quick setup.
- Use Lua scripting for flexible parametric modeling.
- Export models in multiple formats for various applications.
- Leverage real-time rendering for immediate visual feedback.
How It Works
LuaCAD allows users to define 2D and 3D shapes using Lua scripts, which are then processed by a Rust engine. This engine can either perform Constructive Solid Geometry (CSG) operations directly or generate OpenSCAD code for rendering.
The use of Lua's operator overloading simplifies the syntax for combining shapes, making it intuitive for users familiar with CAD modeling.
