The preferred method for sending us you models is to create a package.
This process will generate a single file which includes all the
files necessary for your model to run. To create a package, follow
these instructions:
Open your model
Click File | Create Package ...
Click the Save As button and enter a name
for the package file. (Be sure to remember the location to which
you are saving the package file.)
If you are not sending a package file, please be sure to the
.IGX, .PMD, and any .SFT files used in you model.
