Always save a master vector file (DXF, DWG, or SVG) alongside any print job (.rld, .prn, .plt). The print format is a dead end for CAD.
Here’s a helpful, practical post about converting files (typically from RasterLink or specific point-cloud/scan data) to DXF (Drawing Exchange Format for CAD). Note: “RLD” isn’t a universal CAD format like DWG or DXF. It’s most often a proprietary format from Mimaki RasterLink (used for printing/plotting), or occasionally a LiDAR/point-cloud format. The conversion approach depends entirely on which RLD you have. 1. Identify Your RLD File Type First | Likely Source | Typical Use | Can convert directly? | |---|---|---| | Mimaki RasterLink | Print contour cuts, registration marks | ❌ No — it’s a print job file, not geometry | | RLD (rare LIDAR) | 3D point clouds | ✅ Yes, but requires conversion to ASCII → DXF | | Renamed .rld (custom) | Unknown legacy | 🔍 Open in a hex/text editor to check header |
If you share the of your RLD file (open in Notepad++ → HEX-Editor plugin), I can tell you exactly which type it is.
