Professional solvers and applications for serious engineering work.

Pro
Application
CAM Studio
Import geometry, generate 2.5D and 3D toolpaths, simulate cuts, and post G-code — without leaving the browser. Tool libraries and machine profiles sync to your account.
Open CAM Studio
Pro
Pro solver
Bridge designer
Design any bridge type — girder, truss (Pratt/Warren/Howe/K/bowstring), arch, cantilever, cable-stayed or suspension — and find how much it can carry. A unified 2D frame finite element solver computes axial forces and bending moments, then checks combined stress yield, Euler buckling and cable slack to report the maximum load factor and critical member.
