Adjust Camera position should be according to 'help' :
Click render tab / camera panel / adjust
It is not on the camera panel. please advise. used frequently in 2008 version, now frustrated.
The 2014 version of ACA.cuix had a flyout on the Camera panel that held the Adjust tool, which ran the AECCAMERAADJUST command. The command still works in ACA 2015, but for some reason the tool is missing from the panel.
You can type AECCAMERAADJUST at the Command: prompt, or edit the CUI to add the tool back to the Camera panel. Since the other two tools were changed from side-by-side Large to stacked Small tools with a blank third row below, you could even add the command to that third row, and not have to use the flyout to get to it.
Here is a Screencast showing how to add the Adjust tool to the Camera panel in ACA 2015:

I have posted a blog article that has the aforementioned Screencast embedded in it. The blog article provides a more detailed outline of the steps shown in the recording (which does not have audio narration).
