If you want to use your LEGION Model File in the FDS (Fire Dynamics Simulator) fire-modelling software, you must export your model as an FDS file. The FDS software can produce slice files or Plot 3D files for use with Environment Maps.

The Export FDS process is handled by a four-page wizard, each page of which is covered in sequence in the following three procedures (pages three and four are contained in the third procedure). The whole process creates a file which can be opened by FDS software.
