Create a triangle from elemented selects

NGUYEN_NGOC_DUE · March 29, 2025, 7:48am

I don’t understand why when I hover over an object with the intention of creating a triangle on the surface of that object, but when I draw the object, it appears at the wrong coordinates, even though I have used **localToWorld** in my code but it doesn’t work.
Can you take a look at the code and help me solve this issue?

TriangleLines.ts

const components = componentRef.current;
const world = worldRef.current;
const container = ifcContainerRef.current;
const model = modelRef.current;

if (!components || !world || !container || !model) {
  console.error("Invalid references");
  return;
}
