Thanks for your post stowbury.

You can customize the default project file that opens every time creating
new project on JUDE.

1. Open the default project file "JudeDefaultModel.jude".
You can find it in JUDE install folder.
e.g）C:\Program Files\JUDE-Community\JudeDefaultModel.jude

2. Delete models/packages from the default model that you don't need and
create business analysis types that you would like to use.

3. Overwrite it.

Now every time you create a new project file, your customized project file opens.

*Note*
8 data types for an attribute, (boolean, byte, char, double, float, int,
long and short) will still show up in the drop-down list by default with customized project file.
