1.   A major review of existing modules in the fabrication and welding area is now under way.

2.   Eight existing modules are being revised and two new ones are being developed in video production and role play.

3.   You start either from scratch or by modifying an existing module, changing colors, shapes and movement.

4.   This indicates which of the revised modules replace existing modules.
