2D structural analysis in the browser
ForceSketch
ForceSketch began with a TT principal sketching a structure on a napkin in a meeting and wishing he could get analysis straight from the sketch. It’s now a free, web-based tool that’s nearly as quick as sketching: draw a structure on desktop or mobile, add loads and supports, and get full results (reactions, deflections, moment, shear, and axial forces, plus utilization) in real time. It solves indeterminate structures, runs and compares several models at once, and supports metric and imperial with standard and custom sections, image underlays, dimensioning, and shareable sketches.
Behind it, a Grasshopper definition runs the analysis with Karamba through the ShapeDiver API. TT engineers use it for fast early-stage checks and quick verification; it’s also used to teach students, including in the ACE Mentor Program, and a “mini-game” leaderboard for the lightest structure pushed it to around 1,000 users.
