Open freecad 3D autocad

You can create and edit general purpose parametric 3D models with our app FreeCAD Online. Click in the following button to create or edit 3D CAD models: 



This is FreeCAD, a parametric 3D modeler open source made to design objects of any size.


FreeCAD features:


- Complete CASCADE Technology providing 3D operations on complex shape types, and supporting techniques like brep, nurbs curves and surfaces, a wide range of geometric entities, boolean operations and fillets, and built-in support of STEP and IGES formats

- Parametric model so that object are based on properties or even depend on other objects.

- Modifications are recalculated on demand.

- Modular architecture with multiple plugins.

- Import/export using the formats IFC , OBJ, IGES, STL, DXF, SVG, STEP, STL, DAE OFF, NASTRAN, VRML in addition to FreeCAD's native Fcstd file format.

- A Sketcher with constraint-solver to draw 2D shapes.

- Robot simulation module that provides ways to analyse robot movements.

- Drawing sheets module that permit to put 2D views of your 3D models on a sheet.

- A Rendering module to export 3D objects for rendering with external applications.

- BIM-like workflow, with IFC compatibility. 

- Graphical creation of planar geometry like wires, lines, rectangles, circles  or arcs in any plane of the 3D space.

- Modeling with straight or revolution extrusions, fillets and sections.

- Topological components like edges, vertices, wires and planes.
