💅 BREP INTERSECT (nged) 💅

ok so bestie, this is a page from the BRL-CAD MGED User Commands manual — the nged fam — and it's all about the brep intersect command. buckle up, it's niche but it's lowkey iconic 🎀

✨ NAME ✨

brep intersect — intersect the components of whatever BRep solids you point it at, no cap 🫶

🌸 SYNOPSIS 🌸

brep {obj} intersect {obj2} {i} {j} [PP|PC|PS|CC|CS|SS]

🦋 DESCRIPTION 🦋

These are the low-level routines that do the actual intersecting of elements of BRep solids, plus the visualization of what comes out the other side. it's giving backstage pass energy 💅

So basically you're visualizing the intersection of two BREP objects. The last argument is the vibe check: it says which portions of each object you want to intersect. and if you just... don't pass it? it defaults to SS. that's it, that's the whole thing ✨

Here's the whole menu, one by one:

  • PP — intersect a point from the first object with a point from the second 🌸
  • PC — intersect a point from the first object with a curve from the second 🎀
  • PS — intersect a point from the first object with a surface from the second ⭐
  • CC — intersect a curve from the first object with a curve from of the second 💜 (yes, "from of" — that's the original's wording and we're keeping it, don't come for me)
  • CS — intersect a curve from the first object with a surface from the second 🦋
  • SS — intersect a surface from the first object with a surface from the second 🔥
default is SS if you skip the argument. iykyk 🙈

🌈 EXAMPLES 🌈

Example 1. visualizing a surface/surface intersection, the main character of this page 👑

mged> brep hull.brep intersect cutter.brep 0 0 SS

that intersects surface 0 from hull.brep with surface 0 from cutter.brep, and then draws the resulting intersection curves. slay 🔥
