OpenSCAD: Free 3D Modeling Software
OpenSCAD is an open source, free 3D modeling software used for creating solid 3D CAD models. It is script-based and uses a programming language to define the geometry of models rather than an interactive graphical interface.
What is OpenSCAD?
OpenSCAD is a free and open source 3D computer-aided design application that allows users to create 3D models for 3D printing and other applications. It has a unique approach that is based on programming a model's shape using code rather than interactively manipulating a graphical representation.
Some key features and characteristics of OpenSCAD include:
- Open source software licensed under the GNU General Public License
- Text-based scripting language to define 3D models using code
- Supports parameterized 3D modeling, allowing designs to be customized easily
- Ability to create and import 3D primitives like cubes, spheres, cylinders etc and combine them using union, difference and intersection operations
- Supports modules and recursion, allowing reuse and hierarchical design
- Has basic CAD tools like extrude, rotate, scale to manipulate shapes
- Focuses more on constructive solid geometry rather than freeform surface modeling
- Exports STL files for 3D printing or OFF, DXF, CSG for other applications
- Available for Linux, Windows and macOS
- Steep learning curve compared to GUI-based CAD software
- Popular for programmatic and parametric modeling for purposes like 3D printing
Overall, OpenSCAD is a versatile open source option suitable for programmers to create parametric 3D models for fabrication, architecture, engineering and related applications.
