OBJ-Loader | mtl Files into Indices , Vertices , Materials , and Mesh | Service Mesh library

my problem is that i have buttons : "view" button that enable OrbitControls , "move" button that disable OrbitControls so i can use DragControls, "cube" button that add a cube (or many cubes) to the scene and everything works fine, but when i added a "remove" button so i can remove the cube, it didnt work it says that the cube is not defined. So what should i do ? `

I have a problem that when I use DragControls on an object like cubes or cylinders or spheres it works: I can drag these objects but when I use it on loaded objects with OBJLoader it doesn't work I cant drag them PS : I’m using OrbitContols also and it works fine with Geometry objects but not with loaded objects.

while i try to run OBJLoader it give the error. Attempted import error: 'OBJLoader' is not exported from 'three' (imported as 'THREE').

I loaded the material and texture information from the Obj file based on this code (https://github.com/Bly7/OBJ-Loader). Now I want to load Sponza and render it. However, there are 10 or more textures, and even if all are passed to the shader, it is necessary to correspond to the appropriate vertices. Looking at the result of loading from the Obj file, textures are assigned to each part.

Example.

I am trying to render a 3D model using Three.js on the browser and also trying to add annotations similar to https://sketchfab.com/3d-models/interactive-test-778258c754a74d37a72d3274b80c6ce1 . I am using https://manu.ninja/webgl-three-js-annotations/ as a reference. I tried following the first half of the article which just adds the screen projections but i dont see any annotations in my model.Would really appreciate any help in understanding what i am missing.
