Peter Porta: You need a ThingWorx extension ( ThingWorx VuforiaExperienceService Extension Package) which contains VuMarkEnabledShape(old)/ThingmarkEnabledShape Thing. This extension is not currently available on marketplace and has limited to PTC internal use.
Please refer to similar post for detail: https://community.thingworx.com/message/60905#60905
From the subject of the post it is not clear if you are not able to connect Studio to ThingWorx or need to see ThingmarkEnabledShape Thing.
Hi Durgesh - thanks for replying so swiftly!
I am able to connect Studio to to ThingWorx - but the ThingmarkEnabledShape does not show up when searching for it in ThingWorx.
As a licenced partner to PTC I was hoping to get access to that extension - any idea how to get it?
I am currently running the Trial version of Studio and the Composer
