Compare GFs


Compare GFs is not a regular command that you can read about in the manual, but in this COW we wanted to point out that you can visually compare two Geometry Files by using the /SPAWN parameter with the DISPLAY command. For example,
display "Arctic Sea.GF" /spawn
display "Antarctic Sea.GF" /spawn
This provides a visual display of all aspects of the two geometries in adjacent windows. The purpose of the /SPAWN parameter is to leave the display window open.

Do you like macros? A simple macro command would do the same thing:
macro Compare_GFs
display "%1" /spawn
display "%2" /spawn
/
.Compare_GFs "Arctic Sea.GF", "Antarctic Sea.GF"
If you find that two slightly different versions of the same vessel geometry are giving surprisingly different results in the calculations, showing them together on the screen may reveal the reason for the difference.
