MTCAD

Modular CAD architecture with:

• kernel: C geometric kernel, built as a shared library (mtcad_kernel.dll on Windows) using libuv as core library
• gui: C++ desktop frontend (mtcad_gui.exe) using ImGui + Vulkan + SDL3 + STB

Why this split

Keeping the kernel in C behind a stable C API makes it reusable for:

• desktop GUI apps
• web backends (native service process)
• Server seperation
• language bindings later (Python, Rust, etc.)

Build (Windows, CMake)

1. Clone repository:

git clone --recursive https://github.com/Engineer162/MTCAD.git

2. Install vulkan:

https://vulkan.lunarg.com/sdk/home

3. Configure:

cmake -S . -B build

4. Build:

cmake --build build --config Release

Build from VS Code (Ctrl+Shift+P)

Use Command Palette and run one of:

• Tasks: Run Build Task to run the default task (cmake: build all)
• Tasks: Run Task and pick cmake: build kernel or cmake: build gui

The tasks are defined in .vscode/tasks.json and will configure CMake automatically before building.

Notes

• By default, the GUI links against the kernel import library. At runtime, mtcad_kernel.dll must be next to mtcad_gui.exe (or on PATH).
