Use a DXF/DWG/SVG/STEP/STL file

Files with extensions like .dxf, .dwg, and .svg are used to represent 2D shapes, while files with extensions such as .step or .stl are used to describe 3D shapes. These files serve as a means of exchanging design data.

However, these shape-description files alone are not sufficient for immediate machining. While they define the appearance of a shape, they lack the specific instructions needed to transform raw material into the desired form using particular tools and processes.

This involves employing various strategies to approximate the envisioned design as closely as possible. Each type of manufacturing equipment requires an unique approach to achieve optimal results.

Fortunately, this complexity finds resolution through the utilization of "CAM software" or Computer-Aided Manufacturing software. This sophisticated software manages the intricacies of the manufacturing process and produces a job file — often referred to "G-Code" or .cnc / .nc file. This file can be then loaded into the CNC software.

In essence, the process of transforming a design into reality necessitates the intermediary role of CAM software to bridge the gap between the design and manufacturing execution.
