Principia offers a cloud‑native multibody simulation add‑on for Onshape that enables mechanical engineers to run rigid‑body dynamics, joint constraints, and load analyses directly on assembly geometry. Its high‑performance cloud solvers deliver results in minutes, provide real‑time visualizations, and export load data to downstream FEA tools, accelerating design validation and reducing prototyping needs.

Problem
Mechanical design teams often rely on separate CAD, analysis, and manual calculation tools to evaluate motion, loads, and scaling, leading to lengthy iteration cycles, high prototyping costs, and limited insight into system dynamics before physical testing.
Solution
Principia delivers a cloud‑native multibody simulation add‑on that runs directly inside the Onshape CAD environment. The engine models rigid‑body dynamics, joint constraints, forces, and sensors without requiring file export or third‑party software. Cloud‑based numerical solvers provide virtually unlimited compute power, delivering results in minutes. Engineers can verify functional motion, explore scaling effects, and generate realistic load cases—all within the same workspace where the geometry is created. Results are stored securely and can be shared instantly with collaborators or linked to downstream finite‑element analyses, accelerating design validation and reducing the need for physical prototypes.
Target Audience
The primary users are mechanical engineers and product development teams in OEMs, robotics firms, agricultural‑machine manufacturers, and metal‑3D‑printer companies that design complex assemblies within Onshape.
