FreeCAD の主な特徴
現実世界に合わせて作成
FreeCADは主に現実世界の物体をデザインするために作られています。FreeCAD 上で行うすべての作業はミクロン、キロメートル、 インチ、フィートなど現実世界の単位を使用しており、あらゆる単位を組み合わせられます。高精度で信頼性が高いモデルを作成、 編集し、それを3DプリントやCNC加工のためにエクスポートすることができます。また、モデルの2D図面やビューの作成、有限要素 解析などの解析の実行、数量や部品表のエクスポートなどの機能をもった便利なツールもあります。


強力なソリッドベースジオメトリカーネル
FreeCAD features an advanced geometry engine based on Open CASCADE Technology. It supports solids, Boundary Representation (BRep) objects, and Non-uniform rational basis spline (NURBS) curves and surfaces, and offers a wide range of tools to create and modify these objects, including complex Boolean operations, fillets, shape cleaning and much more.
Wi(l)dly パラメトリック環境
All FreeCAD objects are natively parametric, meaning their shape can be based on properties such as numeric values, texts, on/off buttons, or even other objects. All shape changes are recalculated on demand, recorded by an undo/redo stack, and allow to maintain a precise modelling history. Properties of one object can drive the value of properties of other objects, allowing complex, custom parametric chains that could only exist in your wildest dreams. New parametric objects are easy to code.


Python everywhere
While the FreeCAD core functionality is coded in C++ for robustness and performance, large parts of the external layers, workbenches and and almost all the communication between the core and the user interface is coded in Python, a flexible, user-friendly, easy to learn programming language. From Python code, you are able to do just anything in FreeCAD, from simple one-line commands in the integrated Python console to recording macros, coding your own tools up to full custom workbenches.
File formats frenzy
FreeCAD allows you to import and export models and many other kinds of data from your models such as analyses results or quantities data to dozens of different file formats such as STEP, IGES, OBJ, STL, DWG, DXF, SVG, SHP, STL, DAE, IFC or OFF, NASTRAN, VRML, OpenSCAD CSG and many more, in addition to FreeCAD's native FCStd file format. Add-on workbenches can also add more file formats.


A parametric constraints-based 2D sketcher
FreeCAD features a state-of-the-art Sketcher with integrated constraint-solver, allowing you to sketch geometry-constrained 2D shapes. Sketches are the main building block of FreeCAD, and the constrained 2D shapes built with it may then be used as a base to build other objects throughout FreeCAD, be it either with the dedicated Part Design workbench or any other workbench.
A large (and growing) multi-specialty ecosystem
FreeCAD offers dedicated workbenches for a variety of purposes such as CSG modeling, simple 2D CAD drafting, NURBS surfaces, architectural or BIM modeling, 3D printing, CAM and CNC, point clouds, working with OpenSCAD files, designing industrial robot trajectories, doing Finite Element Analyses, and much more. FreeCAD also provides easy tools to install and manage add-on workbenches and macros developed by the users community.
