As part of our migration from our old ThingWorx Community to the PTC Community, we updated and moved some content. For ThingWorx Tutorials and other PTC generated technical enablement content - these can now be found in our IoT/AR Tech Tips Board. For this particular Tutorial, you can find that here.
