A reminder about changing emissivity....

There has been some discussion about editing zone construction
files. This is not a good idea in terms of QA (because the changes can
be easily lost and some subtle errors can creep in when people
manually edit files).

The best way of doing it is to use the materials database and get a
copy of the standard materials database into your model (there is
an option in the project manager to do this) and then find a material
that is similar to what you want an make a copy of it and change the
surface properties as necessary as well as changing the documentation
of the material to reflect what you changed and what the original
was.

Then in your construction database use the new material and the
altered surface properties will be imported into your model files.

Again - it is not a good idea to manually edit the zone files!
