Can't place Target accurately

Trying to place camera and target positions in one model to match another, to get like-for-like views. Can place camera ok but target decides to be slightly off.


Command line entry:

Set values are off:

Rhino 7.1.20329.13011, 24/11/2020


Hello - I wonder if maybe it is auto-adjusting from this setting:
I’ll experiment.

@jeremy5 - just to make sure - put a W in front of the coordinates to force world coordinates. Just ot eliminate the possibility of a slightly off CPlane. I’ll continue to experiment but I can’t see this problem yet here in a simple case.
