You don't need to use afcads. In featurepanel, you can autmatically install the afcad files that come with NL2000 v2.9x Featurepanel can be found in the featurepanel directory in the folder of nl2000. See also the user manual how to use featurepanel. Thanks, I found that section in the feature pane...

Are there any FS2004 AFCADs for NL2000 available?

The only ones I have found on this site are for FS2002.

Thanks.
