We regularly work with PLT files from various CAD systems, and reaConverter has proven to be the most efficient solution for batch converting them into accessible formats like PDF and TIFF. Its ability to handle PLT files accurately, without losing line weights or scaling, is essential for maintaining the integrity of our technical drawings. Combined with command-line support and Watch Folder automation, it fits perfectly into our production workflow, saving hours of manual processing each week.
