SimplerCAD
What it is
SimplerCAD is a browser-based 3D design workspace for creating, inspecting, and preparing models. It supports parametric modeling and sculpting, with tools for primitives, connectors, and printer hardware fittings. Mesh-editing options include extrusion, cuts, reduction, smoothing, remeshing, hollowing, repair, and splitting disconnected parts. Users can import STL, OBJ, GLB, and OBJ plus MTL ZIP files, and export STL, GLB, or OBJ. Design checks cover relative strength, overhangs, mesh printability, bed fit, solid volume, and estimated PLA weight; the strength scan indicates relative risk and critical-section location, not an exact breaking-load prediction. WebXR supports true-scale model inspection on a VR headset. Work stays locally in the browser, while signed-in users can save projects to My Designs. The free plan includes core modeling tools, saved projects, and STL export. Maker adds unlimited projects and advanced mesh tools; Classroom provides student management and education support.
For and against
For
- Free plan includes core modeling tools and STL export
- Supports parametric modeling and sculpting
- Includes mesh and printability checks
- WebXR allows true-scale model inspection
Against
- Strength scans do not predict exact breaking loads
- First iOS version does not offer accounts or cloud saving
The verdict
SimplerCAD combines modeling, mesh editing, design checks, and several import and export formats. The free plan covers core modeling and STL export; users needing advanced mesh tools or classroom functions can review the other listed plans.
Who it suits
SimplerCAD may suit people preparing designs for 3D printing, prototyping, fabrication review, or learning 3D design. Its Classroom plan lists student management, collaboration, curriculum projects, and education support.
