GENIO roads
GENIO files that define a road can be exported from a number of third party road design software packages, including Bentley MXROAD and 12d Model.
The file extension for the GENIO file must be *.crd, *.inp, or *.mos.
You can also use the Trimble Access Roads software to create a GENIO .inp file that contains models extracted from a .12da file. This is particularly useful if you are not able to export GENIO files from the 12d Model software.
