Excellent! Thank you. I did engineer a solution last night using an antique copy of the Carrara 1.0 Bible. In that, they tell you to start building the path with the fourth tool in the line-up, the Extend Path tool, instead of the Add Point tool. That worked, but the points, while they looked good in the first view, were found to be all over the ballpark in the other two views, so a lot of adjusting was necessary.

I will re-build the test animation using your suggestion. Thanks again.
