Native engine

The native engine runs on your server, on Windows (x64) or Linux (x64, arm64). Clients connect to the ClassCAD server, which starts an engine for each session. It comes with the Business plan.

Download

Under Downloads on your account: choose the platform and the version, download the archive and unpack it. The page shows an install script for each platform as well.

Key

The engine reads its key from .classcad.appkey in its folder. Make one under Downloads → Key and save it there. It is valid until your plan's period ends, at most a year; then make a new one.

Start

The ClassCAD server needs Node.js 20 or newer.

./classcad-socketio.sh

On Windows, classcad-socketio.cmd. The server listens on port 9091.

Connect

npm install @buerli.io/classcad

import { init, SocketIOClient, BuerliCadFacade } from '@buerli.io/classcad'

init(id => new SocketIOClient('ws://localhost:9091', id))

const facade = new BuerliCadFacade()
await facade.connect()
const api = facade.api

const part = await api.v1.part.create({ name: 'Flange' })

This is the program from WebAssembly; only the init line differs.

Python and .NET

The API also comes as packages for Python and .NET. Under Downloads, API wrappers, are the packages for the engine version you run, with their install commands: an API package and a connector for each language. The .NET packages are installed from a local NuGet source; the connector's dependencies come from nuget.org, so both sources need to be configured.

from classcadconnector import SocketIOClient

client = SocketIOClient(url="ws://localhost:9091")
await client.connect()
api = client.getApiU()
part = await api.v1.part.create({"name": "Flange"})

var client = new ClassCAD.SocketIOClient("ws://localhost:9091");
await client.Connect();
var api = client.GetApiU();
var part = await api.v1.part.Create(new() { name = "Flange" });
