Treat Single Region Parameters As
When a region described in a .poly or .smesh file has only a single attached parameter, TetGen leaves the interpretation of that parameter up to the user.
This option allows you to specify whether to interpret single parameters as:
Move to World Coordinate System
If the value is Yes, the companion dataset files (having the same name as the primary file) are read in order to acquire the coordinate system and the data necessary to convert points to the world coordinate system.
In the absence of companion files with the same name as the primary file, FME looks in the same directory for files named global.*.
