[GF] Fault Boundary Loading from SMT Fault Polygon files

[Youens, Simon]

Dear All,

I've been busy loading (or trying to load) fault boundary polygons and
have some feedback for everyone.

1. Only use Applications, Data Manager, Interp-Import. Do not try to use
Data Management, Loaders and Unloaders, ASCII load. I could never get it
to work. Life's too short.

2. Use the Interp-Export selection to view and/or modify an appropriate
file format and then export some existing fault polygons to create an
example file to help you create your own file.

3. I started with the 'fbm_gf.ifdf' format file and modified it. The
default format truncates long horizon and fault names, so this needs to
be fixed.

4. Use Excel or a script to create the input polygon file. In the case
of the SMT fault polygon files, you will need to repeat the first point
in a polygon at the end of the polygon, in order to close it. Contact me
offline if you want advice on how to do this in Excel.

5. WARNING. Do as I say and not as I did. If you have a horizon name in
your input file, which I like to do, so that I don't have to remember to
'override' anything, MAKE SURE this horizon exists before you try to
load the file.

6. If you try to load a file associated with a non-existent horizon, not
only will the load fail, but IESX will 'hang' and you have to exit
Geoframe and restart. A serious bug, which I have reported.

7. However, there is no problem with non-existent fault names. An
appropriate fault will be created.



Regards,
Simon
