 * Changed referenced to `beam` in `Drilling` to `element`. 
 * Changed `Drill Hole` and `Trim Feature` GH components to generate the relevant `BTLxProcessing` type rather than the deprecated `FeatureDefinition` type.
 
+* Changed `Show_beam_faces` gh component to `Show_ref_sides`, which now takes an `int` index and shows the corresponding face
+  including origin corner.
