RLD files are typically "Read" files associated with specific CNC machinery or older proprietary CAD/CAM suites. They often contain 2D geometry data used for cutting paths (routing). Because they are proprietary, they lack the open documentation that formats like DXF or DWG possess.

In your target CAD software, use the SCALE command with Reference . Pick two known points on the drawing and enter the correct real-world distance.

Proprietary "project" files that store not just geometry, but also laser-specific data like speed, power, and layer priority for Ruida controllers. DXF Files:
