VR with Solidworks
The best way to view to view any 3D content in VR is with the Unity game engine. “Best” is subjective here. Unity is a complex and powerful game design package that offers well-supported and high performance VR viewing modes with the HTC Vive. Unity is also available for free use. The downside is that you’re introducing an unfamiliar and near redundant software package to your workflow.
Unity will act as our VR viewer but we need to find a way to import our Solidworks files. There is no direct data exchange between Solidworks and Unity. Solidworks can export a variety of neutral geometry formats but not the .OBJ type that Unity accepts. The good news is that there is a free macro to export Solidworks geometry as .OBJ files.
These are the broad strokes for the work flow. We now know enough to put together the process.
Set Up
Install Unity
Visit https://unity3d.com and download the installer. You will need to create an account. The Personal edition will work fine for our purposes.
Installation should be straightforward, nothing special is required.
Set up .OBJ export macro
Neil Larsen has written an excellent macro to export Solidworks geometry as an .OBJ file.
It is available with installation instructions on this page: https://forum.solidworks.com/thread/54270
We only need the Free SolidWorks OBJ Exporter v2.zip file.
Follow the instructions inside to install the Solidworks macro. The included Blender scripts are not required.
Set up Unity template
CAD-VR has created a Unity template to streamline the process of using VR with Solidworks.
The template has support for the Vive headset, controllers, and teleportation built in. Thanks goes to thestonefox and his Unity VR Toolkit for making this possible.
The template is available here.
Extract the “Solidworks Template” folder to a safe working location.
Workflow
Export .OBJ data from Solidworks
For this guide we will be using a model of a Gudel Cartesian gantry system available as a .STEP file from their site. Sample files for this project are available here.
Import the .STEP file and save the new assembly.
Click the .OBJ export macro button to bring up the export dialog box.
Most of the default export settings are fine but I needed to select “Output mesh with Y axis up” due to my coordinate system.
Click “RUN EXPORTER” and wait patiently until you get a “Complete” dialog box.
You should now have a new folder in the location of the saved assembly with a .OBJ file.
Import into Unity
Launch Unity and open the Solidworks Template project folder that was saved above.
In Unity go to Assets > Import New Asset
Select your .OBJ file and click Import
Unity will process the geometry and the asset will appear in your project file at the bottom of the screen.
The asset will have a property dialog associated with it that appears on the right hand portion of the screen.
In the asset dialog box check the “Generate Colliders” box and click Apply. This will make teleportation easier later in the process.
Import into Scene
Your geometry is now in your project file but not yet in the scene.
The scene is empty except for a large base slab that will serve as the scene floor.
Import your geometry by dragging the asset file from the project file at the bottom of the screen to the scene file tree on the left hand side of the screen.
Your geometry should appear in the view space.
There’s a good chance your geometry is not correctly oriented and is intersecting with the base plane.
Click on the geometry asset in the left hand file tree and a transform dialog should appear in the right hand side of the screen.
Adjust the position and rotation values to correctly orient the geometry. You may need to adjust the scale values if your dimensional units did not import properly.
For the example files included use the following values:
Position X:10 Y:3 Z:0
Rotation X:90 Y:0 Z:0
View in VR
Launch SteamVR and make sure the service is running
To view the scene click the Play icon in the top center of the screen. This will launch Unity into a rendering mode and output the display to your Vive headset.
The Vive controllers can teleport you around the geometry by using the touch pad button.
Conclusion
Unity offers great VR viewing capabilities. The geometry exchange could be streamlined between the packages but it’s a minor hiccup for now. The provided template is a nice sandbox for importing geometry. I hope this guide is helpful in realizing VR as a powerful design tool.

CAD + Augmented & Virtual Reality
By: Justin Hoey | Posted 9 months ago
Augmented Reality (AR) and Virtual Reality (VR) are already here!
Most of us have already been exposed to AR apps such as Pokémon GO or enjoyed a roller-coaster simulation in VR. But have you ever wondered what your 3D design could look like in augmented & virtual reality? WakingApp, an Autodesk partner, was established almost 4 years ago with the vision of enabling designers to create and view AR and VR experiences easily without writing a single line of code.
The ENTiTi platform is designed for non-programmers, allowing the creation of dynamic behaviors through a patent-pending technology with a smooth, easy-to-use interface. The platform is cloud-based and the content is interchangeable. Whenever content is generated or updated, it is immediately available for viewing on multiple platforms including mobile devices, GearVR, and desktop devices such as the Oculus Rift & HTC Vive.
ENTiTi has recently launched a Fusion 360 add-in that allows seamless content-generation. With just a few mouse clicks, you can turn your CAD into AR or VR, and share it with your friends, clients, and colleagues. Content generated using the add-in will be password-protected by default, so that only you and your authorized viewers will be able to view it. You get the password directly to your Autodesk account’s registered email address within minutes after the process has begun.
But it doesn’t end here! If you want to add interactivity to your design, such as controlling colors, animating the object and much more – you can do so easily, by downloading ‘ENTiTi Creator’ and editing your existing projects created by the Fusion 360 add-in. It’s easy to use and requires no prior AR or VR experience.

Designing from scratch in VR
Mindesk is the first interface in the world bridging Rhino 5.0 and Virtual Reality!
It is part of a wider project that will allow soon to create from scratch 3D CAD models in VR. Mindesk works with HTC Vive™, Oculus Rift™, and Oculus Touch™. It is recommended that your PC is VR-ready.
