Hi Coyo
Thanks a lot for your reply. There’s a lot of useful information to help improve my selection skills.
Selection Tips Noted:
1. Check vertex groups (Unfortunately, this model does not come with vertex groups, but I will keep this tip in mind for future use).
2. Edit mode > “P” Separate by loose parts.
3. Select all > “M” Merge by Distance.
4. Convert triangle mesh to quads to reduce the number of faces to select.
5. “Shift+G” Select Similar.
6. “Ctrl+i” Invert selection.
7. After selecting, SAVE and NAME the vertex group in the Data Tab.
8. Ctrl Numpad +/- to grow selection
Thank you very much for sharing.
