💅 NAME 💅

okay so bestie, this is bot_flip from the nged manual, part of BRL-CAD User Commands — it reverses (i.e. flips) all the facet normals within a BOT primitive. slay. ✨

✨ SYNOPSIS ✨

bot_flip {bot} [bot2 bot3]...

🦋 DESCRIPTION 🦋

Reverse (i.e. flip) all the facet normals within a BOT primitive. that's the mission, no cap.

When you're viewing a BOT with the MGED e -m1 or draw -m1 command, if all the exterior facets are black and all the interior facets are shaded (red by default), then this command will flip the normals resulting in all exterior facets to become shaded and all interior facets to become black. literally the glow-up 😭💅

bestie, it is recommended to run the commands bot_vertex_fuse then bot_face_fuse before running bot_flip. do the prep, okay? 🫶

Note: using bot_flip will toggle the orientation of right and left-handed BOT primitives. The orientation of unoriented BOT primitives will not change. no cap.

🎀 EXAMPLES 🎀

Example 1. Flip a BoT whose outward-facing normals are reversed.

mged>bot_flip imported_shell.bot

Reverses every facet normal in imported_shell.bot, which is a common follow-up after finding that the model's outside faces render as backfaces in shaded mode. iconic tbh. 👑
