I want to render many buildings on the map with Cesiumjs, and Does cesiumjs support blender and OBJ model?
Cesium supports glTF, which is an open standard from Khronos designed for 3D assets on the web. The Cesium website has a drag-and-drop converter to convert COLLADA files to glTF:
http://cesiumjs.org/convertmodel.html
You can export COLLADA files from Blender.

I think there are two way visualize your 3d model
Using Cesium Ion (Ion can convert to 3Dtiles or GLTF)
Convert to GLTF
You have to convert 3D OBJ file to GLTF
Blender can export 3D model as GLTF or GLB
After Conversion, for load GLTF model at CesiumJS sandcastle sample

I have a Revit file with two different 3D views which I can see them in Autodesk viewer ;however, when I extract model manifest, there is only one OBJ file and I can extract only one.
How can I extract the OBJ of all the 3D views that are created in the model?
Thank you
You need to translate your file into OBJ first using the ModelDerivative API.
According to Supported Translations, Revit files doesn't support OBJ derivatives, so can't translate the whole file into OBJ.
But you can extract the geometry, take a look at this tutorial : Extract Geometry in the official Autodesk Forge documentation.
In the translate payload you need to pass the model guid of the 3D view you want to translate, so you should be able to translate all your 3D views.
I would like to convert assemblies from a .RVT model to three.JS to .USDZ for AR. I have a list of assemblies and want to process each individual file into the final format of USDZ for AR. Does anyone have any good recommendations? I’m thinking Model Derivative IFC to three.JS to .USDZ but would love know the best method for this! Thank you!
The ModelDerivative API allows you to convert your RVT file (and many others) into SVF (or SVF2) to be used by the viewer for example. Then you can use Forge Convert Utils package to extract the geometry and create a glTF of your model.
glTF is widely used for AR but if you need to use USDZ, you can easily convert your model with this kind of tool : USD_From_glTF
I an trying to use .dwg file in web app. I have recently find this (https://github.com/aalavandhaann/blueprint-js) works base on three.js file. while dwg is not compatible with three.js is there anyway to convert dwg file to json nad use it in threejs?
I guess not much people need to import three.js json file to Blender, but I lost my original Blender file and want to recreate it from json that I exported earlier.
Latest three.js git only has exporter and no importer.
I tried using old json importer (from this link https://github.com/Bangybug/three.js/tree/master/utils/exporters/blender/2.71/scripts/addons/io_mesh_threejs) but it does not load back UV maps, only model and textures, so I wonder if there is some importer that could do this?
Unfortunately, there currently is no working importer to get three.js models into blender. You could try to load the object in three.js and then export it using the THREE.OBJExporter(). You might have a good chance to import that resulting obj-file into blender.
So I am working on a 3D model for days in Fusion 360 and now I need to get it into Unreal Engine. The problem is that Fusion 360 supports CAD formats and Unreal Engine only supports .FBX file formats.
Use Blender to Import the Fusion 360 STL file format and then export from Blender as an .FBX. (GO Blender TEAM !!!)
You can also export directly to FBX from A360.
Go to your file in A360
Click the toolbox icon
Export and select FBX
Give the server some time to do the file conversion
You can then download the file.
