What SimplerCAD is
SimplerCAD is a browser-based 3D design workspace for creating, inspecting, and preparing models. It supports both parametric modeling and sculpting, with primitives, connectors, and printer hardware fittings. Mesh tools provide face extrusion, plane cuts, reduction, smoothing, remeshing, hollowing, repair, and splitting of disconnected parts. Users can import STL, OBJ, GLB, and supported OBJ plus MTL ZIP files, then export STL, GLB, or OBJ. Built-in analysis covers relative strength, overhangs, mesh print checks, bed fit, solid volume, and estimated PLA weight; the strength scan indicates relative risk and critical locations, not an exact breaking-load prediction. WebXR enables true-scale inspection in a VR headset. Work is kept locally in the browser, while signed-in users can save projects to My Designs. The Free plan costs nothing and includes core modeling tools, saved projects, and STL export. Maker and Classroom pricing is on request. SimplerCAD is available on web, Android, and iOS.
Who it suits
SimplerCAD suits people designing for 3D printing, prototyping, fabrication review, or learning 3D design. Classroom features target educational use, while Maker adds broader project and mesh capabilities.
What it does well
