Hello Shane,
Global Mapper also added support for E57 import last year at user request, but doesn't seem to be used much.

Hello,
You want a converter from LAS to E57? The LAS format is also a data exchange format and a much simpler one than E57. So I would suggest you ask the ArchiCAD 19 tech support to add an importer for the LAS/LAZ data exchange format. This can be easily realized usong either the LASzip DLL, Howard's older libLAS library, the LASlib library that powers LAStools or Howard's new PDAL library. In the meantime I suggest to try CouldCompare to convert LAS to E57 ... ?
