You should never "translate" your models into .geo format: to load a 
.step or an .iges file just open it... that's it.

The same way as for other models: all the mesh size functions are 
available for all model types. To use the geo-type scripting commands on 
a .step file, you can e.g. write a .geo file that contains

   Merge "file.step";
   // geo scripting command here...
