The STL, or Standard Triangle Language, file format has been around since the '80s and is supported by most modern 3D modeling applications. In particular, the STL format has become something of a standard format within the area of 3D printing, despite the rise of more modern formats such as 3MF.
STL files come in two flavors: binary or text format. The text format is human-readable, making it easy to perform manual edits, but can lead to very large file sizes. As you can imagine, the binary format is much more compact and represents the majority of the STL files you are likely to encounter.
The format itself is very simple; the 3D model is represented by a sequential list of triangles, with each triangle defined with 3 points consisting of their X, Y, and Z positions, along with an additional vector that contains the face normal (the direction the face is pointing). There is an additional attribute block for each triangle; however, this is largely unused and thus unsupported.

When converting 3D model or mesh files using our STL converter, we will attempt to convert color materials into a suitable format for use in the converted file.

A SKP file is the native file format for the popular SketchUp 3D modeling application. SketchUp is a growing platform, popular with industrial architechs and 3D design enthusiasts alike who like the ease with which complex 3D models can be produced.
The SKP format is capable of storing complex 3D models and their associated geometric data, such as vertices, edges, faces, materials, and much more. The format is well supported, and it receives updates containing new features on a regular basis.
Due to its popularity, the SKP format is supported by many 3D modeling applications via an import option, and where an import option may be missing, our own SKP conversion tools can convert to and from the most popular 3D formats.
