All these movements, together with some specific printer commands like the ones to control the extruder temperature or bed temperature, are ultimately compiled in the G-code file. This file can then be transferred to the printer for execution. Different densities of infill (in yellow), as generated by Cura slicer, from solid to hollow.
SolveSpace v3.0 is able to export 2D sketches and surfaces into DXF/DWG (AutoCAD version 2007), PDF, SVG, EPS, and HPGL file formats. Wireframes can be exported as DXF and STEP files. Polygon meshes can be exported as STL and Wavefront OBJ; NURBS as STEP. SolveSpace is able to export models in STEP, STL, and G-code for reuse in third-party CAM ...
G-code (abbreviation for geometric code; also called RS-274 [citation needed]) is the most widely used computer numerical control (CNC) and 3D printing programming language. It is used mainly in computer-aided manufacturing to control automated machine tools , as well as for 3D-printer slicer applications .
The STL (stereolithographic) file format is the oldest and most widely used file format in 3D printing. Developed in 1987 by 3D Systems , STL was initially designed for stereolithography , but it has since become the standard format for FDM printers.
Once finished, the g-code can be sent to the printer for the manufacture of the physical object. [8] The open source software, compatible with most desktop 3D printers, can work with files in the most common 3D formats such as STL, OBJ, X3D, 3MF as well as image file formats such as BMP, GIF, JPG, and PNG.

.gcode is a plaintext format that contains the g-codes listed one after another, it is not a 3D file of an object but rather the toolpath. Some programs can use the toolpath and operation commands to generate a reconstruction of the object based on some assumptions about what the g-code file is written for. -- 2003:D6:170C:5A82:BCC3:6C66:317 ...
2.5D objects are often greatly preferred for machining, as it is easy to generate G-code for them in an efficient, often close to optimal fashion, while optimal cutting tool paths for true 3-dimensional objects can be NP-complete (nondeterministic polynomial time complete), although many algorithms exist.
An IGES file is composed of 80-character ASCII records, a record length derived from the punched card era. Text strings are represented in "Hollerith" format, the number of characters in the string, followed by the letter "H", followed by the text string, e.g., "4HSLOT" (this is the text string format used in early versions of the Fortran language).
