I was used to extract faces for populating my solid faces. Do I still need to proceed this way?
No, you can directly select solid faces and HyperMesh will populate the relevant ELSET. However, if you still have some faces, you can use this preference to move SURACE to 3D faces when deleting your 2D elements.
I imported a model from 2017 or 2019 and some of my surfaces are missing. How to proceed?
As a starter, make sure to check the Sets category (or SetSegments if dealing with legacy interface).
Also, in 2017 and 2019, some entities were written with double quotes, which lead to some errors. Then you may need to remove these double quotes before loading the model.
