STL_BOOLEAN(1)

💖 STL_BOOLEAN 💖

okay bestie, gather round, because this one is literally the mesh math girlie of your dreams ✨

🌸 NAME 🌸

stl_boolean — she does CSG operations on two STL files, no cap 🎀

---

🦋 DESCRIPTION 🦋

stl_boolean performs CSG operations on two STL files. that's the whole vibe, that's the assignment, she ate 💅

usage, and yes you need both A and B, this is a two-hander:

stl_boolean -a <stl file A> -b <stl file B> [ -i ] [ -u ] [ -d ] <output file>

so like. you hand her file A with -a, file B with -b, tell her which flavour of boolean you want with one of the little flags, and then the output file sits at the end being the main character it is 👑

under the hood she's doing a mesh CSG boolean operation on STL files A and B using BSP trees. BSP trees!! binary space partitioning!! she's not just pretty, she's smart 🧠✨

now the flags, bestie, there's only three, you got this:

• -i — performs the intersection of A and B 🌈 like, only the part where they overlap? that lil shared slice? iconic
• -u — performs the union of A and B ✨ and this is the default, so if you're lazy (same) you don't even have to type it
• -d — performs 'A minus B', which produces the volume present in A but not present in B 🍓 think of it like carving B's shape out of A, subtraction core

lowkey important: -u is the default, so if you pass nothing, you're getting a union whether you asked for it or not. she's decisive like that 💜

and that's it!! that's the whole page!! short and sweet and she does exactly what she says she does 🫶

kisses, bestie — this was stl_boolean v1.2, from June 2025, sitting pretty in the User Commands section of your manual. go boolean something cute 💖✨🎀
