If any kind of 3ds to las conversion is possible, it would be probably related to export of GIS/navigation data done using ArcGIS. Unfortunately, we have not found any specific information about such export, just that it should be generally possible.
Since 3DD format comes from ESRI software, if you struggle with this export or need something specific, it might be best to reach out to their support or online community.
