We can show camera positions, one at a time, and store them as Named Views and recall them from that list.
I am marking each one on the plan as I set it up, snapping to the Viewpoint the point of a small cone in a block also containing text to match the camera number so someone can point at that Camera position and ask “What does it look like from there?”
Is there a more efficient way to store some portion of the Camera View icon itself? Something that automatically displayed the lens length would be good. I bet a Grassshopper could do it.
