3D CAD tools

Model in 3D, open STL, OBJ and STEP, export as STL, 3MF, OBJ or glTF, and simulate strength, air and water.

3D modelling and simulation CAD + simulation Build a model from primitives or from a sketch (extrude, revolve), open STL, OBJ and STEP, export as STL, 3MF, OBJ or glTF, and simulate: stress and deformation with finite elements, air in the wind tunnel, or turn a body into water and watch what happens when it falls. Everything happens in your own browser — the model is never uploaded. Open → 2D CAD (DXF/DWG) 2D CAD Draw and edit DXF/DWG, like AutoCAD: lines, polylines, rectangles, circles, arcs, text and dimensions, with commands and typed coordinates, snapping, ortho mode and layers. Open a DXF, edit it and save it again as DXF, or as PDF or SVG. Everything happens in your own browser. Open →

The strength analysis is meant to show quickly where a part is loaded most. For a check that goes with a permit application, a structural engineer should look at it.
