xeokit .BIM Importer

---

Import building models from the open, free and simple .BIM file format

---

The xeokit SDK allows us to import 3D models from .BIM, a JSON-based file format specifically designed for lightweight, user-friendly, and human-readable storage and sharing of 3D BIM models.

.BIM is an open-source and minimalist file format for BIM that's built to be easy to read and write. Essentially, .BIM is a transfer format that contains triangulated meshes with a dictionary of information attached to them.

To import a .BIM model into xeokit, simply use the loadDotBIM function, which will load the file into both a SceneModel and a DataModel.

Installation

npm install @xeokit/dotbim

Usage

In the example below, we'll import a .BIM file into a SceneModel and a DataModel. The @xeokit/core!SDKError class is used to handle errors that may occur during the process:

import { Scene } from "@xeokit/scene";
import { Data } from "@xeokit/data";
import { loadDotBIM } from "@xeokit/dotbim";

const scene = new Scene();
const data = new Data();
const dataModel = data.createModel({ id: "myModel" });
const sceneModel = scene.createModel({ id: "myModel" });

if (dataModel instanceof SDKError) {
     console.error(dataModel.message);
} else if (sceneModel instanceof SDKError) {
     console.error(dataModel.message);
} else {
     fetch("myModel.bim")
         .then(response => response.json())
         .then(data => {

             const fileData = JSON.parse(data);

             return loadDotBIM({
                 data: fileData,
                 sceneModel,
                 dataModel
             });

         }).then(() => {
             sceneModel.build();
             dataModel.build();
         });
}
