✨ NMG_FIX_NORMALS (nged) ✨

okay so bestie, this is the nmg_fix_normals page from the BRL-CAD User Commands manual, and honestly? it's a little hero of a command and nobody talks about it enough 💅

---

🌸 NAME 🌸

nmg_fix_normals — it fixes the surface normals of an NMG solid. that's it, that's the whole vibe check 🎀

---

🦋 SYNOPSIS 🦋

nmg_fix_normals nmg_prim

---

💖 DESCRIPTION 💖

so the nmg_fix_normals command attempts to repair inconsistent or inverted surface normals in the NMG solid nmg_prim. bestie, it literally makes sure all the face normals point consistently outward from the solid — and that is required for correct rendering, raytrace hits, and Boolean operations. like, no cap, you actually need this. 🔥

and when is this the move? it's useful after manual NMG editing operations — think adding faces with nmg_cmface or nmg cmface — where the winding order or normal direction may not be consistent across the mesh. yep, that happens, and that's exactly the moment this command swoops in. 😭

note the word "attempts" — the page says it attempts to repair them, so don't come for her if it's not a magic wand ✨
