New 3D view * Simple 3D models can be imported and review(It is recommended to choose 'Google' as your browser and turn on the hardware acceleration). * How to import: "Top menu - File - New - 3D Model", after importing, you can find it at "Library" - "3D Model", when importing, you need to set the unit for the model. * Download the 3D model/library:    The documents of 3D models only support OBJ and WRL(VRML) yet. * OBJ: Make both the OBJ and the MTL are in a shared zip package, and then import the package to EasyEDA.Download OBJ here(The MTL would be downloaded at the same time): * WRL: It should be imported directly. * [https://library.io/explore/3dmodels](https://library.io/explore/3dmodels) * [https://github.com/KiCad/kicad-packages3D](https://github.com/KiCad/kicad-packages3D) * [https://grabcad.com/](https://grabcad.com/) * [http://www.3dcontentcentral.com/](http://www.3dcontentcentral.com/) * [https://github.com/FreeCAD/FreeCAD-library/tree/master/Electrical%20Parts/](https://github.com/FreeCAD/FreeCAD-library/tree/master/Electrical%20Parts) * Assign 3D model for PCBlib:  There is a 3D models manager used to adjust the 3D models being pointed. The same packages will point to one 3D model. via: "Topbar menu - Tool - 3D Model Manager，similar with Footprint manager. Others: A new layer named '3D models layer' was added to PCB layers. PCB 3D preview is generated in editor, and the large documents review won't fail again. but that will take some time.
