For a CNC (Computer Numerical Control) project, you’ll need precise digital files to guide the machining process. Typically, the choice between an SVG or a 3D STL file depends on the type of work you’re planning:

STL (Stereolithography): Best for 3D projects like carving or sculpting. This format contains detailed 3D geometry, allowing the CNC machine to create complex shapes and depths.

SVG (Scalable Vector Graphics): Ideal for 2D designs such as engraving, cutting, or laser work. It contains vector paths that can be easily scaled without losing quality, making it perfect for flat designs or outlines.
