A SCAD file, short for "Script-based Computer-Aided Design," is a type of plain text file used primarily in the field of 3D modeling and design. It is commonly associated with OpenSCAD, an open-source software tool used to create 3D models using constructive solid geometry (CSG). Unlike traditional CAD software that employs a graphical user interface for modeling, SCAD files are written in a scripting language. These files typically have a .scad extension and contain a series of commands and parameters that define the shapes, dimensions, and operations required to construct the 3D model.

Within a SCAD file, users can define basic geometric shapes such as cubes, spheres, cylinders, and more complex shapes by applying operations like union, difference, and intersection to combine or modify them. The use of a scripting language in SCAD files enables users to create parametric models, allowing them to easily modify dimensions and characteristics of the model by changing variables in the script. This flexibility makes SCAD files particularly useful for designing customizable objects and prototypes, where various iterations may be required to meet specific design requirements.

Once a SCAD file is created and the script is defined, it can be rendered by the OpenSCAD software, which interprets the script and generates a visual representation of the 3D model. Users can then preview the model, make further adjustments if needed, and export it to standard 3D file formats like STL (stereolithography) for 3D printing or rendering in other CAD software. SCAD files have gained popularity among the maker community and designers due to their simplicity, modifiability, and compatibility with 3D printing technologies, facilitating the rapid prototyping of complex objects.

The OBJ file format is a 3D graphics file format used to define complex 3D models, including geometry, materials, and textures. OBJ files are text files, making them human-readable and easy to modify by hand. The downside to this ease of readability is that the files can become rather large when dealing with large or complex 3D models.

As mentioned, the OBJ format stores not only 3D model geometry but also materials and textures. These materials are usually defined in a separate file with the MTL file extension and specify geometry rendering details such as diffuse and specular color, transparency, and much more.

The OBJ material file can also reference external texture files. These are usually JPEG or PNG files; however, these can be older formats, such as TGA. Where materials are used, the OBJ file will also contain material names preceding the geometry faces they should be applied to. If textures are referenced, the geometry will also contain texture coordinates (UV) for each vertex.
