BIM Viewer is a WebGL based front-end project that I created in my spare time. It is aimed to display BIM (Building Information Modeling) models, it supports gltf, obj, fbx, ifc, dae, etc. Since it is build on top of three.js, you can easily extend it to support any format that three.js support.

This project is not mature yet, it's more like a demostration. There are many TODOs as you can see below. It is unfortunate that I could not continue work on it, that's why I make it open source, and I hope it could benifit others who is in BIM/AEC field.

npm install

npm run serve

npm run build

npm run lint

• Orthographic camera

• Distance measurement

• Area measurement

• Angle measurement

• Section plane

• Section box

• Component selection

• Display outline

• Transparent mode

You can add your own projects or models by editing projects.json. Add following to projects.json, and put your models under public/projects/my_project folder.

{
    "id": "my_project",
    "name": "my project",
    "thumbnail": "projects/my_project/thumbnail.png",
    "camera": {
      "eye": [20, 10, 20],
      "look": [0, 1, 0]
    },
    "models": [{
      "name": "my_project",
      "src": "projects/my_project/my_model.gltf",
      "position": [0, 0, 0],
      "rotation": [-90, 0, 0],
      "scale": [1, 1, 1],
      "instantiate": false,
      "merge": false,
      "edges": true
    }]
  }
