Backlog for Beta

• More work on Help page
• More tests for 3D solid logic
• Move 3D code to own crate
• Export to STEP
• Arc dragging
• Broken constraint tools / solver stability (need help!):
• • Lines parallel

Building locally

Desktop

Make sure you are using the latest version of stable rust by running rustup update.

cargo run --release

On Linux you need to first run:

sudo apt-get install libxcb-render0-dev libxcb-shape0-dev libxcb-xfixes0-dev libxkbcommon-dev libssl-dev

On Fedora Rawhide you need to run:

dnf install clang clang-devel clang-tools-extra libxkbcommon-devel pkg-config openssl-devel libxcb-devel gtk3-devel atk fontconfig-devel

On NixOS:

nix-shell to get into a working environment.

Web

On NixOS: cd liquid-cad && nix-shell then trunk serve or trunk build --release

Legacy OS'es:

1. Install the required target with rustup target add wasm32-unknown-unknown.
2. Install Trunk with cargo install --locked trunk.

Locally: Within the liquid-cad directory, run trunk serve to build and serve on http://127.0.0.1:8080. Trunk will rebuild automatically if you edit the project.
