Wuweido is free and always will be.

Wuweido is a professional 3d modeling CAD on mobile (smartphone and tablet). More than just a 3d model viewer dozens of 3d modeling tools are provided to create and modify 3d models to enable you do real CAD work on mobile.
Wuweido is optimized for cad touch experiences. User friendly UI and intuitive workflow make it easy to build complex 3d geometry models with fingers touch and move.
Wuweido can be used in various domains related to 3d modeling such as 3D Art Design 3D Concept Design 3D Printing Mechanical Manufacturing Engineering BIM 3D Geometry & Modeling Education etc.
Wuweido is running on your local devices offline with no need registration. 3d modeling files are persisted on your local storage and your data is yours.
Wuweido allows you to import and export 3d models in standard CAD formats.

Modeling Features:
Wuweido provides a rich set of draft modeling tools to create 3d curves such as Line Segment Poly Line Arc Spline Circle Ellipse Rectangle and Regular Polygon.
Wuweido allows you to create 3d primitive solids such as Box Cone Truncated Cone Cylinder Sphere Torus Wedge Truncated Wedge Pyramid and Truncated Pyramid.
Wuweido allows you to create surfaces or solids from 3d draft curves via advanced sweep modeling tools extrude revolve loft pipe and pipe shell.
Wuweido allows you to build complex geometry shapes from simplex via Boolean operation tools Intersect Subtract Union XOR and General Fuse.
Wuweido allows you to duplicate delete move rotate mirror and scale geometry shapes in the most natural way.
Wuweido allows you to edit geometry shape’s visualization properties such as Color Material Transparency Line Width and Display Mode.
Wuweido provides layers to group geometry shapes as traditional CAD system.
Wuweido is built on a stable application framework and you can undo and redo any data changes in history you can create a new model save it and then close.
Wuweido provides tools to import and export 3d parts and assemblies in STEP IGES and BREP CAD formats. It allows you to interchange data with other CAD modeling software such as Autodesk™ Inventor™ Solid Edge™ SolidWorks™ PROE™ UG™ CATIA™ Rhino 3D™ and OPEN CASCADE™ etc.
Wuweido allows you to export STL and VRML polygonal data formats. STL is de-facto standard in 3D printing.

Precise Modeling Tools:
Wuweido provides smart object snapping tool to capture the geometry shape critical points such as vertex edge center edge quadrant and face center.
Wuweido provides grid snapping feature which support dynamic and static grid density.
Wuweido allows you to input absolute or relative coordinates in Cartesian Cylindrical or Spherical Coordinate Systems.

View Tools:
Wuweido is optimized for devices with multi-touch screen and provides intuitive manipulation of the 3D view by finger gestures.
Tools are provided to navigate to top bottom left right front back and ISO view.
Wuweido allows you to create working coordinate system (WCS) to assist modeling process.

Wuweido design philosophy is similar to Rhino 3D™. It's easy to learn and you can master it in days. If you have experience with Rhino 3D™ you'll find that Wuweido looks like Rhino 3D™ on mobile.
