More about Solidtype

SolidType is a modern, history-capable parametric CAD environment designed for collaborative 3D modeling and precision 2D sketching. Built on ElectricSQL, TanStack DB, Durable Streams, and OpenCascade.js, it combines robust geometric kernels with real-time data synchronization to support complex mechanical design workflows.

Engineers and developers can explore constraint-based modeling while leveraging live Postgres replication, CRDT-powered Yjs documents, and client-side embedded databases. SolidType demonstrates how to architect production-grade collaborative design systems with:

Parametric 3D modeling driven by OpenCascade.js (OCCT)
Constraint-solved 2D sketching for accurate feature creation
Real-time multi-user collaboration via ElectricSQL and Durable Streams
Branching workspaces and projects for experimental iterations
AI-assisted modeling through chat-based tool calling with TanStack AI

The repository includes a complete local development setup using Docker, PostgreSQL with logical replication, and Drizzle-based migrations. SolidType is ideal for developers building next-generation CAD experiences, real-time engineering collaboration environments, or experimenting with advanced sync patterns across structured metadata and CRDT-backed design documents.
