Hi,
If looks like the doxygen documentation in C/C++ code used to generated CubitInteface Documentation is broken, which results to the error in the detail description of the function get_ML_operation_features(). This bug also “ate” the documentation for a number of subsequent functions.
The same error exists in the offline SDK: C:\Program Files\Coreform Cubit 2021.11\docs\Cubit-SDK\namespace_cubit_interface.html
P.S. I tried to parse these files to create Python stubs for the cubit module to simplify its usage in PyCharm, but had to postpone this activity…
