Blender is a great program for editing meshes and in-fact can be used to do basic editing of PCD files. PCD files are the native file format for the Point Cloud Library, a library often used in robotics or machine vision applications. By converting PCD files into PLY files (using a separate tool), it is possible to import PCD files into Blender. However, this can be a hassle if you're primarily working with PCD files. This project is an add-on that enables importing and exporting PCD files directly from Blender version 2.8+ without having to convert to intermediate files.
