Currently .las file format is not supported by default and a third party extension needs to be purchased from Exchange.ai in order to support this.
To avoid this scenario can you please support .las file extension in the future releases.
LAS file is an industry-standard binary format for storing airborne lidar data. The LAS dataset allows you to examine LAS files, in their native format, quickly and easily, providing detailed statistics and area coverage of the lidar data contained in the LAS files.
