Import 3D Modeling Objects

Unity is further a integrated creation platform. While creating objects or scenes in the game or in reality design, it supports to import them from others desgin tools like sketchup, autocad, maya, etc. It mainly supports the following file format: .FBX, .dae, .3DS, .dxf and .obj files. If tools you used support to export the above format, it would be imported into unity. In the document, we demostrate how to import a 3D modeling object into unity.

The procedure to import a object into unity is the same, we take sketchup as the example.

Import Steps

• You have already done a 3D modeling in Sketchup / AutoCAD / Maya, etc.

• Export a 3D object in recepted formats :
  • In sketchup, click file, export, 3D modeling, and save as a .dae file.
  • In AutoCAD, export the model in .FBX format by clicking A (on the most top-left), Export, FBX and select all types and materials.
  • In Maya, you can choose exporting file formats (.DAE, .FBX) by clicking File, Export All, and select the format in Files of type.
• In unity, click Assets, Import New Asset, and choose the .dae (or .fbx, etc.) file exported from sketchup. And you will see the object in the Project View and its sub view Assets.
• In unity, click the imported object and set the following attributes in Inspector. Click Generate Colliders, click Import Materials, choose Model Name + Model's Material on the Material Naming and click Apply.

• Drag the object in Assets view to the scene.
