I can't get the 3D tab to appear in the Panel - how do I do this?
Does the 3D panel appear if menu item 'Window > 3D' is ticked?
I don't get that option on the Window menu - is this an add-in I have to download first, perhaps?
The Cloud Ps has recently increased its system requirements for 3D. Maybe this link will explain why you don't have 3D:
Aha. Thank you. That looks like the job!
