OBJ File
OBJ (Alias Wavefront Object) is a text-based file format for 3D geometry objects which is very popular and widely supported by many 3D software programs. The OBJ file format is capable of storing named group objects, surface materials with transparent colors and texture images, and quads or triangles as geometry primitives. However, our Autoconverter software will simplify every OBJ quad primitive with two triangles as only triangular facets are supported during the OBJ file conversion. It's important to mention that due to a textual format OBJ files will always be much bigger than the binary files, e.g. 3DS (3D Studio) or SKP (SketchUp).
STEP File
STEP (STandardized Exchange of Product) is a very popular file format for the data 3D exchange between different computer systems e.g. CAD, CAM or CAE. As the STEP geometry data are stored in a text form you can expect bigger file sizes when exporting triangular meshes with thousands of faces using the Autoconverter software. However, if your geometry defines manifold solid it will try to create optimized faceted STEP brep representation which should reduce STEP file size by one-third. The STEP file format supports colors per assembly, but without the alpha component, therefore any transparency setting will be lost in the final STEP file.
