Can two different vessel models be joined as in the situation
where an offshore rig is being transported on a barge ?
Yes, you can combine the contents of two Geometry Files into one,
making them into one composite model. Shifting of origins and reversing
the sense of the longitudinal axes (switching bow and stern, port
& starboard) is also quite easy.
There is one compatibility issue to keep in mind when building the
models: duplicate part names are not allowed. For example, you cannot
have a part named "HULL" in both of the Geometry Files
to be combined. Therefore, it would be a good idea to use something
like "RIGHULL" in a model which you expect to be combining
with another model which uses "HULL". Likewise, naming
of tanks should be done in such a way as to assure there will be
Here is an example of the commands needed to combine two models:
