hello,Is there a way to load two .bim files into one view in iTwin.js

[jh9636]

I want to load multiple .bim models into a single view，I would greatly appreciate it if you have any good suggestions.

You can try out the following code, it work for me.

const vp = IModelApp.viewManager.selectedView;

// open a different imodel
const otherIModel = await BriefcaseConnection.openFile({fileName, readonly});

// load the target model to display
const modelProps = await otherIModel.models.queryProps({from: "BisCore.GeometricModel3d"});
const modelId = modelProps[0].id;
await otherIModel.models.load(modelId);

// create a ViewState
const viewCreator = new ViewCreator3d(otherIModel);
const defaultView = await viewCreator.createDefaultView({}, [modelId]);

// can setup the transformation of the model
defaultView.modelDisplayTransformProvider = {
  getModelDisplayTransform(modelId) {
    return { transform };
  }
};

// add it to viewport
const treeRef = createPrimaryTileTreeReference(defaultView, otherIModel.models.getLoaded(modelId) as GeometricModelState);
vp.addTiledGraphicsProvider({
  forEachTileTreeRef: (_vp, func) => func(treeRef)
});

// find the right time to close the other imodel
vp.iModel.onClose.addListener(() => otherIModel.close());
