The following NX error is displayed when either the 'Slot' or 'Groove' design feature commands are selected;
NX License Error: License server system does not support this feature [-18]
The cause of this error is that these commands require a "usr_defined_features" license, in NX 10.0, which may not be available in the license file.
Solution
This issue is resolved in the NX 10.0.1 maintenance release.
The 'Groove' and 'Slot' commands can be accessed using a "features_modeling" license, as in previous versions of NX.
