Assuming the project definition files are in C:\My Projects\project1, the following example generates a batch script in C:\Batch that will run on the host platform using the data that was exported with the project definition.
“<BDT_install_path>\bin\bdt>” -project "C:\My Projects\project1\project.prj"
–target_dir C:\Batch -with_data
where <BDT_install_path> is your installation path.
